I have a '97 Civic DX that I'm putting a built B16A in. I took out the wiring harness from before because it was just a mess and there were bare wires everywhere and some didn't work. My question is, what wiring harnesses can I use that will plug right up to my B16A? I have a P2T OBDII ECU. Can I use a wiring harness from a 96-00 EX?

 

96-98 EX harness with some modifications

 

shoulda just kept the stock harness in and just add necessary wires...but since you took it out, just get a 96-98 civic ex harness and use that...get an obd2a to obd1 conversion harness and get a p28 chipped to run the b16...or just get an obd2a to obd2b harness and just use that ecu you have there...should've kept it simple and just reuse your old harness and add on what was needed...but good luck to you

 

well i still have it, i guess i'll just fix it up and put it back in the way it was.
