WRX wiring question (broad and basic)

pilfflip · 03-03-2005, 05:20 AM

Alright, so I have a couple of questions. So i've been doing research on the subject but can't find a concrete answer really, or else I am just being paranoid about the whole severity of the job ahead of me. The basic wiring idea of the WRX harness is too isolate everything coming FROM the ECU or are there some other sensors i need to make the car run. I know that you need the fuel pump relay and boost solenoid too. I read the article in SCC hybrid how to, a few times and that is a pretty broad guide should i just follow that or is there something more specific that I can get to follow? I'm really intimidated by this swap, I'm not sure why, I just got done helping my brother with an ej22 swap into an '86 DL wagon...but still nervous

you wont use any sensors from your old setup the the stuff you have to solder to the ecu is the power and grounds,rad. fans and some misc stuff around 20 wires or so if you can read and solder you can do it just make sure to have diagrams from both cars and label every wire
