i'm doing obd 1. The car was setup for it and i dont' want to change a billion things. Ideally i want to do an h22 engine, h22 auto, and the h22 ecu. I'm sure it has a different harness as well but i figure with those parts that were intended to go with that engine i should be fine. I dont 'know what the ecu connector looks like but then thats just for the ecu and not everything else..........i dont' think. anybody else done anything like this without performance in mind.
