wrx swap wire harness thinning?

Featured Replies

I have a 03 wrx swap, with the body harness too, in swapping into my 87 rx.

anyways I was looking at the ecu pinout and swa that there's a bunch of things like fuel sensors and such that my car doesn't have. Is there anything I would need to do to bypass any of that and is there any security interlocking the ecu that I would have to "fool"?

My car is a 87 also, so no obd port, It would be nice to have one, I can't find one on the wrx harness, I'm not sure if I could still wire One in and have it work for the engine alone?

You'll have to pin it out from the ECU to the plug. Would be a great idea if you ever plan to tune. I'm not using the one from my WRX harness since I spliced into the OBS one, I could send it to you for $10.

That's what I was thinking, ill probably check my local yard here for a plug since I don't have PayPal
