First of all, I'm new to the forum. Just joined yesterday because I am taking on my first swap! I have had a hand in helping with some other swap related projects but this is the first time I have dove in and attempted to complete one on my own. So here is what I've got: OBD1 P28 chipped ECU Jumper Harness OBD2 civic engine harness already wired for vtec OBD1 H22A OBD2 B16 EM1 trans (I'm doing an H2B swap) OBD2 Injectors OBD2 dizzy I have went through and labeled most of the sensors, still have a couple that I am uncertain of. I need to know what to do about the O2 sensors and can I run the obd2 injectors and dizzy even though it is an obd1 ecu? Also If there is anything else that I have to do to go from an obd2 harness to obd1 engine please let me know, this is pretty new to me. And the EVAP sensor that goes on the manifold won't plug in, are they different on obd1 and obd2? Any input is appreciated, need all the knowledge I can get! Thanks Guys!
