JDM Subaru Legacy BG5 Digital Climate Control System

[MountainBayer]

I have a 1998 subaru legacy L sedan 2.2 L and recently bought a JDM digital climate control system, i have been researching on my own trying to find out how to swap out the stock (manual) one with the auto climate control but i havent had much luck. The package that i bought had the;
Head Unit
Complete dash Harness ( but its for a Right hand drive car so its not an exact swap, conectors are diff. ect.)
Out Side Air Temp Sensor
Sun load Sensor w/ vent cover
High speed fan relay
Inside air temp sensor with tube
Air Mix Motors with linkage
Blower Motor Resistor

i was wondering if anyone has done this conversion before or if they have any info that could help? Like wiring diagrams or pin layouts for the JDM automatic digital climate control?

i think there's issues with the manual heater manifold control that causes it to be incompatible with US cars

[MountainBayer]

i figured i might have a few problem that ill run into and have to create my own modification, but right now all i really need is a wiring diagram and pin layout of the JDM head unit itself so i can find out what wire should be power, AC ect...any info helps though

Climate control sensors and motors

[MountainBayer]

as you can see i should have everything i need, all i need to know is a wiring diagram or pinout for the control unit. because i cant just plug and play with the wiring harness supplied, (its for a JDM right hand drive vehicleso the connectors and wires are different)

[httrdd]

Doesn't the compressor run at different speeds according to demand?

[MountainBayer]

any info on the wiring diagram/pin layout would help?
if you have any info on the JDM BD5/BG5 auto digital climate control please post it or let me know where i can find it, thanks

I have the wiring diagram and pin layout at home. If you would PM me when I return in a couple weeks, I'd be more than happy to scan and upload it for you.

[MountainBayer]

Awsome, ill make sure to do that cause that would be extremely helpfull
thanks

Finally someone is doing this swap, I've wanted to see this get pulled off. Would it be a big bother for you to document this swap well and do a write up when you finish.

[MountainBayer]

not a problem at all, i already plan on doing a well documented write up and posting it. and ill keep you guys up to date on my progress
so far iv already installed the outside air temp sensor and the in dash sun light sensor, and im just waiting on the wiring diagrams and then ill let you know how the rest goes from there.

[MountainBayer]

thanks to YamazakiSubaru i was able to get the JDM wiring diagrams for my car, that has the auto climate controll, so now that i have a better idea of how it should work this project of mine should finally start going somewhere

good luck with it!

lucky for me these are standard in Australian delivered cars as well, not just the JDM variants

Thats good, that means the documents are in english. Anyway you can get an aussie FSM?

i knew they were also standard like that in Canadian cars. However i havent found anyone from Canada or from Australia yet who has a Factory Service Manual. So if anyone knows someone who does have one, or knows where to get one please PM me
its for a 98 Legacy sedan (95-99 years should be the same) I need one for the Automatic digital climate controll

[elislider]

any update on this? just curious :D

[eekay]

Looking to do the exact same thing! I already have the climate control unit but I don't have the sensors or motors yet. Not sure where I'm going to acquire those, actually. Anyhow, I was super curious as to how this stuff would be wired up as the connectors are WAY different. Thanks for posting the wiring diagram though! That'll help for sure.

BTW this is what I was really curious about. English FSMs

Bump for this as I would like to to see the outcome!

Bumping an ancient thread. I occasionally see the automatic climate "head units" on Ebay and they always intrigue me. All the picture links in this thread are dead. Has anyone successfully done the swap in a USDM BD/BG/BK?

This certainly isn't high on my list of things I need to do, I just think it would be cool.

Don't buy this unless you can at least get all the parts for it just like the OP. I bought the headunit not thinking about what else it needed. Luckily only payed $40 with center vent. Check out how the 240 guys do it (google) and it pretty much shows you everything needed to do it on a 240

[Patrick Olsen]

Yeah, most of the time the ebay listings are just the head unit. Only once or twice (in the years that I've had a "Legacy parts" saved search) have I seen all of the bits and pieces.

95 legacy BG non turbo 2.2l

[rkrenicki]

A LHD BG with a 3rd gen BFM (which we have seen before) and digital HVAC.. Is this your car azazawra? Any more information on it?

[azazawra]

not mine(
this car from Kazakhstan.
but I am also trying to do the same

[rkrenicki]

Do you have any additional information on it? a link to some forum or more pictures?

[azazawra]

3rd gen BFM on BG it's not a problem .... but digital HVAC (((((

[TyrWagon]

So... can you swap your HVAC?? I want to do the same... Here in Chile, we have BG5 Twin Turbo with LHD conversion, with HVAC and TWO functionally Turbos...But only EJ20H version engine... These car is only on one region (a region without custom taxes)... but these local people have many junkyards and the rest of the country can buy engine and car parts..

[twistedsymphony]

I'd be interested in any information on where one can acquire the sensors and or the wiring diagrams for this.

if these were indeed available on Canadian cars then there shouldn't be any problems sourcing the sensors new from Subaru here in North America.

[TyrWagon]

Seek to Jankuyado, from New Zeland... On EBay https://sl-i.net/FORUM/images/imported/2015/04/85b8197a3cdf4770d5b2e485e240da28-1.jpg

How much did he charge for the system? I've got a few parts from him over the years. Cool seller.

[rkrenicki]

Staring at $350 including shipping.

Yeah... It's very expensive... But unique... I have a few parts too :( but this is much money for me...

Thats a little high, but doable.

[dynonacht]

Is that everything needed to make the unit work in usdm vehicles?

I'm promising myself I wont buy this, just like I said I wouldn't but soba's morrettes... wait

Who can send me diagram in best resolution for Automatic Climate Control (need pinouts for jdm bg5)
