August 6, 201312 yr 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"?
August 6, 201312 yr I'm in the midst of doing the merge on my 97 OBS. I believe there's 6 wires related to the fuel system that are unused, along with a number of others like small light, drain valve, rear defogger, and etc.http://www.rs25.com/forums/f128/t141937-brydon-teaches-you-merge-harness.html
August 8, 201312 yr Author 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.
