Need ecu pinout help with my swap.

[httrdd]

I am stuck on pining out the svx ecu. The problem I am having is how can I tie in 6 injector pins into a 4 pin harness?

1)Injector for Sxv.
2)Injectors for Legacy.

#1 Injector
#2 Injector
#3 Injector
#4 Injector
#5 Injector
#6 Injector

TO

#1 Injector
#2 Injector
#3 Injector
#4 Injector

[subie/legacy]

I'm not to sure if impreza and legacy are similar but found this
hope it's some help to ya

Thank you, but I have the pinout already. The question I am asking is how to tie in 6 injectors that the Eg33 requires into 4 wires that used to come out of the LGT ecu? Going from a 4 cyl to a 6 cyl. If that makes any sense.

[subie/legacy]

ok my bad.
yeah makes sense.

[Grafton]

well are they any cylinders that sync'd up with another ? ie intake, compress, combust, and exhaust at the same time? you could tie those injectors together

[httrdd]

Yea that is a possibility, but there has to be a different way. I will have to look at the firing order of a 92 svx.

[StatGSR]

im confused, you should be tying in the chassis wiring to the svx ecu, not the svx engine wiring to the the legacy ecu.....

granted i didnt do my wiring but, Im very confused right now

Sorry I suck at explaining things. I have the Svx harness stripped and ready to tie into the Legacy harness. The problem is that I need to tie in the 6 wires that come out of the ECU plug into the 4 wires that come out of the Legacy harness where the ecu used to be. I may be looking at this all wrong.

[StatGSR]

yea, i would think you should just be running the 6 wires from the svx ecu plug right where they need to go (engine). i essentially have 2 full harness entering my engine bay, one is the stripped svx harness, the other is my stock legacy harness.

we put a new hole in my firewall and everything.

[httrdd]

Ok just talked with matt@numbchuxconversitons and I am going about it all wrong. The Svx is a stand alone system which means that the svx harness basically goes right to the motor. A lot easier than I thought! :oops:

[StatGSR]

yea thats kinda what i was getting at. glad matt could clear it up for you.

[ouch1011]

I cannot think of a single Otto cycle engine that would do this.

where did you find this??? i've been looking for a 2.2 pinout for a very long time.

awesome! thank you.

Wait...so what I'm getting from this is you ditch the wiring for the Boxer4 motor sensors altogether and just run those pertaining to the H6? Then run the wires for the lights, clock, et cetera as another harness?
