Installing Heated Mirrors on a car that came without them?

[d1giPhux]

I'm gonna be installing heated mirrors on my 99 LGT soon. The car came with POWER mirrors, but not HEATED. Anyone know what I will need to do in order to install them? I'm guessing:

- Run Wires from the Pos / Negative wire harness on the mirrors to back of heated mirror switch?

If anyone can point me in the right direction.. that would be great. I have the mirrors, and the heated switch.. just wondering about the wiring before i go out and do it. Thanks!

edit:

Here are pictures of the backs of the switches. Stock is on the Left. Heated on the right.

Here are the back sides of the switches.. they appear to be identical. The wiring on the harness of the car also seems to be identical?

The switches are not going to be different. Theres just two extra wires on the mirrors. There might only be one extra wire. Run one over to your rear defroster button and ground the other anywhere. Easy.
EDIT: Disregard this, I see you got a switch specifically for the heated mirrors, Subaru installed heated mirrors without a separate button on some years and thats what I thought you had.

[d1giPhux]

Okay.. so then I will ask you this.

Because I have the heated button that came with the mirrors.. which button should I use? The stock button, or the heated mirror button?

I guess that leave me some options correct? If I wanted to use the defrost button on the 'heated button' switch.. how could I do that?

Thanks.. trying to bend my mind around wires.

[Huffer]

I considered doing this with the mirrors and switches from an Outback, but discovered I need to run new door looms. I couldn't be bothered with that. But if you figure out a different way of doing it, DIY writeup! :thumbsup:

[d1giPhux]

Door looms? What do you mean? yes.. I'm assuming they will have to go through the doors? or.. what are you getting at?

Here is a picture of the front of the switches as well. Stock on left. Heated on right.

https://sl-i.net/FORUM/images/imported/2009/12/front3JPG-1.jpg

Also.. i would like to say this. The wiring coming FROM the car is the same for both the heated switch and the stock.

So my guess is one of the wires on the car harness should be tapped and ran to each mirror. This would be the same as doing it to the rear defrost button correct?

[d1giPhux]

I plugged the heated button in.. and the switch for the defrost (heated mirrors) seems to work. Couldn't I just run the wires from the mirror to the back of this switch? Hmm.. lots of questions, and the more i read the more ideas I'm getting.

This is a useful page:

[impreza_GC8]

I apologize, disregard my first post. I see you got a switch specifically for the heated mirrors. Subaru installed heated mirrors without a separate button on some years and thats what I thought you had.

[d1giPhux]

Well.. technically I could wire them that way couldnt I?

Basically I just need to figure out how to connect the mirrors up.

I could probably wire the two mirrors (+) wire to the back of the rear defrost button.. and ground wires grounded to doors.

I'm just wondering HOW the switch I got may be used. Or if its even necessary?

If i wanted to use the switch. this is what I have observed:

USDM Power Mirror Switch = 7 pins on switch.
Stock subaru wiring on car = 8 wires to connector

USDM Power HEATED mirror switch = 10 pins on switch. However.. it looks like on the front of the switch it has a panel that could be popped out.. so i'm guessing the heated switch only actually uses 8 of the pins.

Either way.. would I connect them like this if i wanted to use the defrost button on the mirror switch?:


Mirror Pos (+) Wire > Connect to defrost switch (non heated switch) or connect to defrost button on new switch (heated switch).
Mirror Neg (-) Wire > Ground to Car

so looks like i need to figure out which wire on the back of the heated switch provides the switching on / off power for the mirrors.. then wire the Pos (+) wire from the mirrors to that?

Seems logical to me?

[jospgut]

i had the same question, so the heated mirrors connect to the rear? if the rear is not working they are not going to work!

[d1giPhux]

Rear meaning.. the rear defrost? I'm assuming you could hook them up that way.. then they would only come on when you put the rear defrost on. However.. i'm trying to figure out how you could use the switch with the defrost button on it.. if possible.

Hoping someone can chime in who's done this before..

[jospgut]

yea, and the right mirror doesnt have the connector for the drfroser, so i thing we have to figure it out to pull some cable

[d1giPhux]

My right mirror has the additional plug with 2 wires. As of right now.. the only way i see to install it is to run both pos (+) from the Left and Right mirrors to the defrost button. Then ground both sides out on the doors..

What do you mean by your right side doesnt have the defrost wiring?

[Reason]

Interesting post, I have the JDM power folding heated mirrors (thats what the extra push out on the right of the switch is for, mirror select) I have the switch installed but haven't done the mirrors. It seems that the heated switch button has power when I switch it on. I just need to make sure that I can hook up the extra set of wires (that may be for the power folding part) I'm waiting to hear back from peugoby to see how his are hooked up.

[d1giPhux]

Thank link i posted has how to hook up the power folding mirrors..

The heated switch lights up on mine as well when you press the defrost button on and off as well. So I'm assuming that the button is at least getting power.. so now i need to figure out how I would hook up the mirrors to the correct wire on the harness.. or something?

Anyone with more info would be GREATLY appreciated. I'm gonna try to make a DIY once i figure all this out.

[impreza_GC8]

I have done this before but it was with Impreza heated/powerfold mirrors and they didn't have a separate button for the heaters, just the button to fold. As I recall I had to run a couple extra wires to the mirrors from the switch, I think one to each mirror for the heater and then i grounded the mirror heaters at the door.

[phi11]

yeah, I ran four wires, to each mirror,
(JDM heated/folding mirrors, but only one of mine are heated, it was a white one, painted green ftl)
anyways, I only got the folding part to work.
I broke two JDM switches trying to do the heated part.
(took them apart, been meaning to post some photos of them)

the FSM ('99) has two wires for the heated part: (edit my page was numbered wrong)

looks like it's fuse no. 3, the other is ground.

[jospgut]

My right mirror has the additional plug with 2 wires. As of right now.. the only way i see to install it is to run both pos (+) from the Left and Right mirrors to the defrost button. Then ground both sides out on the doors..

What do you mean by your right side doesnt have the defrost wiring?


yeah the mirror has two cables, but were the door is it doesnt have a connector

[d1giPhux]

Phi: Do you have that FSM page? For some reason I seem to be missing it or its a diff page.. because mine says lighting on that page? Hmm. Plus.. i have NO clue how to read those confusing things anyways! Id love to understand what the pin out from the back of the heated power mirror switch is!

So why weren't you ever able to get the heated part to work right? I'm trying to figure out what I needa do in order to get it to work..

Do I just need to run the Pos (+) wire from each of the mirrors to the switch? Or what? How did you break your JDM switches?


Damn.. so back at square one! Someones gotta know how to do this!!

Any insight would be helpful!

[Reason]

I have the FSM for a JDM Legacy on my computer somewhere.

[d1giPhux]

Hmm.. thing is.. my mirrors arent JDM. They came from an 97 USDM outback sport.. same with the switch. Not sure how that would help. These arent power folding.. they are just heated USDM mirrors.

[phi11]

the usdm and jdm switches are both made by nissan.
(and both look the same, just one doesn't have the folding part.)

my circuit boards both where fried, by me.
I took the two bad ones apart and made a semi working one.

https://sl-i.net/FORUM/images/imported/2009/12/Picture2png-1.jpg
(sorry so small, I could only take a screen shot)
B and WG are the heated part.
GR and WG make the light go on.

[Huffer]

This is what I meant by getting the looms. It's not enough just to have the switches and mirrors. This is why I abandoned the project. You don't want to have it wired up incorrectly otherwise you could end up with a short, or overheat the heater element by running it constantly (the rear defrost has an automatic timeout).

If you can track down an outback with the heater package you could grab the loom that goes from the switch into the mirror... That's what I was missing.

[d1giPhux]

well.. theres gotta be some way to do it. If people can hook up heated and powered mirrors.. there should certainly be a way to hook up the heated mirrors.

so its looking like the only option is hooking both mirrors to the rear defrost? correct? That way they have the time out and wont overheat.. etc?



B and WG are the heated part.
GR and WG make the light go on.



PHI: When you say 'light'.. you mean the light on the switch correct?

So what do you think my best option is? I can abandon the idea of using the HEATED switch if thats the case.. i just needa know my options here as to whats going to be easiest / work. I KNOW someones done this before.. and it shouldn't be impossible and or dangerous. I mean in all reality.. arent you just switching power on and off to the mirrors? Not sure why that should be so hard to wire up?

Also.. where did you get that wiring diagram.. i cant find it ANYWHERE in my FSM for the BD series cars. I found that page '92' you were talking about.. however it does not mention anything about mirrors anywhere?

Thanks!

then once you find that, it's PDF# 99

(the page number on the bottom of the document is 112)

the page number I gave you before was wrong, sorry.
(I think that I was looking at a '97 fsm then)

yeah, if you look at the " *mirror heater switch ", in the "on" part, (far left hand side)
you see two things ,the B to WG, and next to that is GB w/the bulb icon to WG

I'll take some photos later to night.

you also see that the heated switch shares different wires from the "remote control switch"

[d1giPhux]

What is 'remote control switch' actually?

So what do you think the best way to wire this up would be? Should i forget about using the heated switch and just wire them to the rear defrost?

I'm gonna do this.. either way.. I just wanna figure it out without blowing / burning out any switches and hopefully without popping any fuses.. and causing problem. You seem to be pretty good at this electrical crap.. so thats awesome.

Did you ever get your heaters to work? or no?

EDIT: This is the CORRECT wiring diagram we are talking about. Its size is huge.. so follow the URL:

http://www.designlabx.com/subaru/electr ... agram2.png (http://www.designlabx.com/subaru/electrical/mirrors/wiring_diagram2.png)

Also.. any clue where i can find the PIN OUT diagram for the switches?

Powered but non-heated switch has 7 pins
Powered w/defrost heated switch has 10 pins.

[phi11]

the pin out is on the bottom of the page,


i6 then you match the colors to the numbers.

I never did get my one heated mirror to work,
but I never tried that hard, after circuit board went bad,
plus, I keep my mirrors closed almost all of the time anyways.

the 'remote control switch' moves the mirrors up, down, left, right,
(a,b,select start, lol)
the 'change over switch' is the "left or right mirror"

[phi11]

everything with a * is the outback wiring that you need.

[d1giPhux]

If i did get the outback wiring harness for both doors.. how hard would it be to connect it up? Wouldnt it just be as easy for me to run my own wiring.. i mean.. it can only be a few wires per mirror (2 max i would guess). Hope i can figure this wiring diagram out as to what I'm gonna need to do.. cause i really want these hooked up!

Under the 'mirror heater switch' ON part.. why are there 2 connections being made.. and none in the 'OFF'? What does the short line with the squiggly in it mean? (Under the ON section)

-----------------------------------
EDIT:

So here are what the 2 different switches look like on the back:

USDM NON-HEATED switch (does not have defrost button) uses the following pins (shown in red):

https://sl-i.net/FORUM/images/imported/2009/12/usdm_nonheated-1.jpg

USDM HEATED switch (has defrost button) uses the following pins (shown in red):

https://sl-i.net/FORUM/images/imported/2009/12/usdm_heated-1.jpg

It looks like the difference between the two switches would be pins '3', '1', and '6'.

These 3 pins correspond to the following:

Pin # 3 = WG (White / Green?)
Pin #1 = R (Red?)
Pin #6 = BrR (Brown w/red stripe?)

The STOCK wiring harness that comes FROM the car has all of the wires for all of the pins EXCEPT wiring for pins # '1' & '6'.

That's basically all I have figured out so far. Basically.. i needa figure out what this means.. or what I'm looking at.. and what I need to do. Too much technical shit.. and for some reason I'm confusing myself as to WHAT all these wires do.


double edit:

do you think the 'folding' mirror wires are shown on this diagram? otherwise I cant figure out why there would be 3 unused pins / wires that need to be ran?

[d1giPhux]

For an easy to read version of how the mirrors look to be hooked up.. i edited the wiring diagram. Check out my version by clicking on the link below. I'm assuming its correct.. however, I'm not sure.

[phi11]

Do you have a muti meter?
The extra two pins are for the foldind part.
I'll post my photos when I get home.
I've seen dead pins before, like on my edm headlight washer.

[d1giPhux]

I do have a multi-meter..however.. I'm not super good with electronics and testing shit.. tho I'm sure I could learn pretty quickly as I've been told how to do it before. I keep looking at this diagram.. and I'm trying to figure out some stuff.. ]

The 2 wires coming out of the mirrors are 'WG' and 'GR' .. does that stand for White w/green stripe & Grey wires?



This is how I see the connections coming from the mirrors.. all the way to the back of the heated switch:

Mirror > GR Wire > #20 pin on b30 connector from both sides > 2 wires merge 2 one wire (pin #17) on i2/i3 connector> FB 13 > PIN #4 on car harness > mirror switch in car

Mirror > WG Wire > #13 pin on b30 connector from both sides > 2 wires (#13) merge 2 one wire (pin #4?) on i2/i3 connectro > PIN #3 on car harness > mirror switch in car


Couple of questions about things.

On the WG wire.. where it merges from both sides @ i3 connector.. does it merges to PIN #4? Does this mean it share PIN #4.. or what? Or am i just reading the diagram wrong?

Pin #4 is the BR wire.

Why does it do this?

This is what I'm talking about:

https://sl-i.net/FORUM/images/imported/2009/12/i38-1.jpg

after that.. it seems to continue to pin #3 on the harness going to the switch.

dammit.. i think i'm making this too complex.

[Reason]

I can read and draw building blue prints, but wiring diagrams look like chicken scratch to me :smt017

You guys figure this out so I can hook mine up lol :smt023

[d1giPhux]

Yeah.. it looked like chicken scratch to me at first.. but now I'm understanding it more and more. Thats why I made this wiring diagram.

http://www.designlabx.com/subaru/electr ... _cheat.png (http://www.designlabx.com/subaru/electrical/mirrors/wiring_diagram_cheat.png)

Its aimed at the way you would look at the car from the back.. mirror on both sides, then it goes all the way back to the wiring harness in the car. Basically I just need my questions cleared up and I should be good to rock and roll.

However.. i still havent figured out if this is THE BEST way to hook it up. Or whether i should just forget the heated switch and install it using the defrost button.

[New GT]

I will take a look at this on Monday at work. We have Alldata and I can print off the pages to compare them side by side. My 04 Outback Legacy has the heated mirror option, so I will compare those diagrams to the one for my 99GT and see what is what. I will let you know what I come up with.

[d1giPhux]

If you can.. don't compare them to the 04 outback.. try to compare them to something closer in years. I think the 99 Outbacks also had the 'all weather package' which included heated mirrors. That would be awesome!! Can you scan anything or get the diagrams from the alldata stuff?

edit: Also.. can you get the wiring diagram print out from the 99 LGT rear defrost button? I wanna see how that hooks up as well just in case I gotta wire the mirrors to that.


Thanks a bunch!

[New GT]

I was just looking at the 2 diagrams for a 99 Legacy Outback Sport. The 2 don't look that much different from each other. It gets confusing when you switch back from page to page. I will have to print them out to compare them side by side. This really does not look too difficult to do as long as you have a switch for the heated mirrors. As far as I can tell the timer should be in the switch to turn the heated mirrors off. I'm not understanding the part about wiring in the rear defrost switch.

[d1giPhux]

I would just wire the mirrors to the rear defrost switch.. we'll.. because its a switch, and also because I've heard that's how they wired it for some models. Not sure about the 99 Legacy GT Limited w/all weather package..if they even exist. But thats one way it seems possible to do it..as according to this DIY:

http://www.jdmspace.com/DIY/powerfolding.htm

He wires them to the back of the defrost switch. I'm guessing really that IS a very good possibility.. since we'll.. you would want them to defrost at the same time, it can provide the power, and also has a timer.

However... you say the switch has a timer? Do you know this for sure? I would think this is likely.. because in the FSM.. looks like they are on different fuses (them meaning rear defrost, and mirror switch).

let me know what you find. Also, if you can screen grab / copy / or do anything like that and send it to me.. would be GREATLY appreciated. My mind is like a mess of cables right now looking at all this and trying to figure out IF there is anything the wires connect to inbetween the mirrors and the harness going into the switch.

Thanks a ton!

[phi11]

you can see where the board fried.
(I should post these photos in the right area)





the point of post these pics is, I do not believe that the switch for the heated mirrors
has a timer, it's just a push switch.

[New GT]

d1giPhux could you post a better pic of the rear of the 2 mirror switches? It looks to me like the switch for the heated mirrors has 2 extra wire pins. The 2 wire harness connectors you posted also look like they are identical. Are they for the mirror switch or for the mirror connections in the door?

[d1giPhux]

PHI: So you think because there IS no timer.. that the best option is to hook it to the defrost then huh? Why exactly do you need a timer anyways? How did yours burn out btw.. just hooked up wrong.. or what?




The 2 harness pics i posted are the wiring harness coming FROM the car.. and going into the back of the mirror adjustment switch.

The mirror switch.. the heated one, has 3 extra pins.

Power mirror switch = 7 pins
Power HEATED mirror switch = 10 pins

https://sl-i.net/FORUM/images/imported/2009/12/switch11-1.jpg

[New GT]

Ok, so I checked the heated mirrors on my 04 and they are just on off. They reset when you cycle the key.

[d1giPhux]

I'm not understanding what your saying about the switch.. or what your saying in general? :?:

edit:

okay.. so looks like what we have figured out here is.. it would be best to hook to rear defrost button? Is that correct?

anyone know where to find the pin out for that switch? I'm no good at finding shit in the manual sometimes..

[New GT]

The switch itself is an on off switch meaning that is all that it does. The power being cycled by the ignition key also resets the switch meaning that when you cut the car off the power to the heated mirrors is also cut off, then they will have to be turned back on when you restart the vehicle.

[d1giPhux]

roger that.

Alright.. so it looks like I'm gonna be installing these using the rear-defrost button @ some point soon.

Weird that these cars would have a seperate switch for the mirrors.. when it seems like the mirrors have no timer, and the switch has no timer.. etc. There must be SOMETHING missing from these wiring diagrams.. or something. Otherwise it doesn't make much sense to me.. or I'm just stupid. LOL :smt023

[New GT]

OK, looking at the wire diagrams side by side, there are only 2 wires that need to be installed. The GR wire that is also the fused power supply is one of the wires. It needs to be run to each mirror. The other wire that needs to be run is from the mirror switch itself. The wire needs to be run from spot #3 at the mirror switch and it needs to go to both mirrors from there. Re-reading your first post on this page, it seems like you were reading the diagram correctly.

[d1giPhux]

Any chance you can scan those wiring diagrams you are looking at and post them up?

Can you further explain what you mean about how you see the wiring? Do you think its really necessary to worry about running it on its own fuse?

Not sure how Id go about wiring it up.. so basically both of the mirrors will merge into one wire for the POS (+) and then run to a fuse, then run to ?

also.. which of the wires to do you suspect as being Pos (+) and Neg (-)? Think WG is pos?

[New GT]

I do not have a working scanner, but they are just like the ones you have. The GR is the battery positive as it comes directly from a fuse. The other wire runs from the switch itself, the switch completes the circuit. The GR wire comes directly from a fuse, so no, you will not need another fuse. You will need to run another wire from the GR wire to each mirror. Then you will need to run another wire from the #3 position in the connector on the mirror switch to each mirror. Basically that is all you need to do.

[d1giPhux]

basically what I need to do is find out WHAT wires are already wired up in the car.. and which ones are missing now.. that way I can add them into the wiring-mess-equation.

Because the Positive wire is coming directly out of the fuse box.. where the hell do I find it to connect the POS (+) wire for each mirror to it? Would i splice the wire coming out of the back of the mirror switch? Or what?

The NEG (-) wire I'm assuming will have to be completely wired from the mirrors down as well.. tho I'm not really sure. Hmm.

edit:

EDIT: Fixed wiring diagram colors / pin out wire colors

Also.. here is a picture of the wire colors.. looking at the back side of the switch.

These are the wire colors going into the switch and corresponding with the pin numbers shown on the switch:

https://sl-i.net/FORUM/images/imported/2009/12/wire_colors-1.jpg

Pin #1 = Red
Pin #2 = Black
Pin #3 = White w/ Green Stripe
Pin #4 = Green w/ Red Stripe
Pin #5 = No Wire
Pin #6 = Brown w/ Red Stripe
Pin #7 = Light Green w/ Red Stripe
Pin #8 = Red w/ Blue Stripe
Pin #9 = Black w/ Red Stripe
Pin #10 = No Wire

As if you were looking at the back of the switch like so:

https://sl-i.net/FORUM/images/imported/2009/12/switch_backJPG-1.jpg

[New GT]

Your connector and pin-out you have posted is backwards. pin 1 is the red wire and pin 6 is brown with red stripe. the pin positions and colors are read and looked at from the front of the connector not the back. It looks like you already have the wires for heated mirrors in that connector, so now you need to check at the mirrors themselves. There may even be another connector attached to the door that would go to the heated mirror. The wire colors would be white/green and green/red, they will be 2 pin wire connectors. I would go check, but it is cold and dark outside right now. If you do not get to it tonight, I may have time to check tomorrow. If you need to PM me you phone # and I will give you a call.

[d1giPhux]

Okay.. i fixed the wiring color picture, as well as the pin out color chart i made.

The mirror switch harness in the car is already wired for the heated mirrors.. however, the wiring harness in the door that goes to the mirror is non-existant. The only wiring that goes from the mirror is the regular 3 pin plug..and the door 'harness' is not wired for the 2 pin extra heated plug on the mirrors.

[Dodge Aries K]

As I have a 1996 Outback with the cold weather package (heated seats, mirrors, and block heater) I can assure you the heated mirrors do not automatically power off and neither does the rear defroster. You have to physically turn them off if you activate them. If you leave them on when you turn the car off they turn back on when you start it again.

[d1giPhux]

Wow.. thats weird. So its like the fog lights where you have to turn it off and on by itself? Strange... doesn't that wear them out / break them easier then having a timer? Hmm.. don't know if I really like that.. thats strange.

Thanks for the info.. definitely clears a few options up! Now I just need to figure out HOW I want to wire it. The newer legacies are controlled by the rear-defrost button / self timed button correct? Hmm.. wonder if that means they got rid of the separate defrost button on the mirror switch for a reason or not..

[Huffer]

As I have a 1996 Outback with the cold weather package (heated seats, mirrors, and block heater) I can assure you the heated mirrors do not automatically power off and neither does the rear defroster. You have to physically turn them off if you activate them. If you leave them on when you turn the car off they turn back on when you start it again.

So basically the same style as cruise control. Off by default when the car is on, and switches off when ignition power is turned off.

Odd that your rear defroster doesn't power off automatically - every Subaru I've been in (95-06) has that feature built in. Haven't been in a 96 Outback though, only 98-99 Outbacks). The Subaru block heater is activated by just plugging it into a power source though.

[d1giPhux]

You should confirm that its not on a timer / does not shut off when you turn the car off. That seems VERY strange.

If I wired these using the heated switch.. how exactly WOULD it time out.. or would it not? seems like I'm missing something here?

[Dodge Aries K]

THey turn off when you shut the car off... but if you leave em on they are on if the key is on and off when the key is off.

[d1giPhux]

Here is another useful link to check out. In this DIY the guy uses a subaru relay and wires to the fuse box?

My defrost switches off by itself. I can see the harness connectors for the heated mirrors in the diagrams above. The connector for the left door is D6, the connector for the right door is D16. Now weather or not they are in the vehicle remains to be seen. I need to take my door card off to check for my self. I also checked the mirror heater switch on my 04 and it is always on after you turn it until you switch it off, even if you turn the car off and then back on again.

[lorensson]

Kind of resurrecting this thread...

Has anyone successfully upgraded from heated mirrors to heated + electronic folding mirrors?

[d1giPhux]

^ I think so.. If not.. you could just combine the folding mirror DIY + this DIY and you would be golden!

[Mr Evolution]

Were you able to get those heaters working with the stock switch???

[d1giPhux]

Stock switch.. meaning? I have them wired up the rear defrost switch. In my opinion this is the best way to do it!

Hi there, nice work!

I've got a UK model 95 GX which came with heated mirrors. I've just got a pair of heated Power Folding mirrors and the mirror switch that goes with it. I think Reason had the same thing going, but not sure whether he sorted it.

Can anyone enlighten me about how to go about wiring this up?

Cheers guys

I'm pretty sure you just wire the heated element to one relay (in my case the rear defrost) and then the folding part to another relay / switch. It shouldn't be too much harder then what I did.. just need to wire the folding part to another relay I'm pretty sure. I've seen other DIY's for different subaru's on the subject, but never one EXACTLY for our cars. However you can take the knowledge in those and try to apply them to your model year.

Cheers dude, I have some mirrors coming this week so I'll have a look at it. I'm not an electronics whiz, but will report back if I get it sorted and try to take pics along the way.

Good luck! Once you get stuff going you will see its not as hard as it seems. Just takes a lot of patience to complete the job, and some friends. Check out the threads I posted in the beginning of this DIY and you will find some stuff that will help your mind out a little bit. Also try google searching for 'subaru folding power mirrors install' or something along those lines and you will find people who have done them before on their subaru as well. Basically you will need some type of relay for the power folding part I'm pretty sure, and also need to wire the defrost leads from the mirror to the rear defrost on your car.. or you could get yet another relay and wire it to that as well. You could grab the relays off a junk car, online, or somewhere else. Good luck man, let me know how it goes!

Bumping Old Thread

I tried to do this to my Legacy L the other day and this is what I found out. All the wiring diagrams posted in this thread are helpful but until you dig into the actual car harnesses you can't determine what is actually required.

From the mirror switch connector I6 to connectors I3 + I4 the wire necessary is in the loom. From the bulkhead connector B38 (the other side of I3) to the door connector, the wire is not in the loom. It is not in the door looms either.

So to wire the mirror heaters correctly, the wire needs to travel next to the door harness to to harness behind the mirror switch pin 3 and 4, if you have the heated mirror switch. Pin 3 is ground, pin 4 is power. You can cut pin 3 since it only is the ground return for the mirror circuit. You must splice pin 4 since it provides power to the entire remote controlled mirror circuit. So the wiring would look like this: 2 wires from each heated mirror connector (black wires on my mirrors) spliced into pin 3 and 4 at the back of the mirror switch.

If you don't have the heated mirror switch, you could put a second defrost switch in, or any other switch you have lying around and still pull the power from pin 4 and find ground at pin 2.

I have not finished this install as I ran out of time and failed to pull the connectors off the donor car so I need to assemble some parts yet.

I can't tell you anything about the power folding part as I haven't studied the diagrams yet.

Later,

Regardie

This thread was about wiring the mirrors to the rear defrost of the car. You don't need to mess with any of it if you do it this way. You can just wire it like i did. However, if you DO want to wire it to a different relay and then to the switch, you might need to figure it out a bit more. Good luck!

You guys are thinking way to hard. Just wire two wires from each mirror to the side mirror switch. One wire from each side is ground the other wire is power, it doesn't matter witch one is power or ground it will work either way since it's only a heater element like your rear defroster or front defroster. I believe I wired mine to the switch it worked since the switch distributes powers and ground when you press the switch. Hope that help. Kind of late but might help others. My folding side mirrors and heater side mirrors work awesome. One more thing if anyone going to try to figure out about the passenger mirror if they can change something inside to make it so that you can see better it wont work. The problem with the folding mirrors is the electric motor is so big inside that the mirror actually bottoms out and no way it will go any more. I have a set of folding mirrors that I played with no luck.

Yes I can confirm this- it wasn't difficult at all to upgrade on my car. Not plug and play, but not hard, just the extra power and ground. Here's a videos of my power folding working http://www.flickr.com/photos/m4th/4783191686/

No I never got around to doing this. I installed them that's about it. I won't even try to wire it up in this weather. I'll touch base on this again when Im ready to do the wiring.

Pictures are worth a thousand words with this thread!!

I was able to get a heater switch that was part of the BH driver side window switch.

Now, looking for used side mirrors with the heater elements just to finish it up.
