Please Help!!! I've got a 99-00 SI B16A OBD 2 going into a 97 Civ EK... Could somebody help me with which wiring harness I should be using? Could I use my 97 EK harness with the P2T ECU (99-00 SI)? Or do I have to get the 99-00 SI harness? I've also got a spare P2P ECU from a 96-00 Civ EX...could i use that instead of the P2T ECU if i use my 97 EK harness?
