I have an S4 swap done into my FB now I need to wire the stock ECU to work. I have the complete engine harness installed and hooked to the ECU. I have one missing connector that I have to build a custom harness for. Its the largest connector to the ECU. The harness itself in a 2nd gen would run under the dash. My question is, what do I need to hook up and where?

I've already wired in the crankcase angle sensor, and the 2nd Gen Ignitors. What else do I need to wire up? Anyone have a detailed write up on this task?

 

This should get you close--the info is for an S4 Turbo.

If you have a SPECIFIC question I could probably help you out--don't just ask how to wire the whole thing up.

i think i remember him having a n/a from another post so...

hey man, you need to check out the 2nd generation parts for sale section, just get one of those guys to chop off the end of that plug for you and splice it together, this will save you a huge huge headache....so bite the bullet and do it right

theres lots of s4's being parted out right now...

Dude do a search on Rex4Lifes posts, he's gotta thread that is amazeingly detailed. If it can't answer 99% of your questions, just give up and ship me all of your mazda parts for my 1st gen project

 

Thanks guys. I'll check those posts and threads.

 

Holy Christ. I thought it was alot more simplier. My brain grows every second I read!

I'd like to note that this is using a GSL-SE. I have an SA22. Its got some 84 parts on it, but most of the wiring is 79. Advantage: I can build my own wiring. Disadvantage: I have to build me own wiring.

Anymore input from anyone? Trying to collect all the information possible.
