Ok ive got a obd2 GSR engine and harness just pulled from my Teg to go into my obd1 Del Sol. I have an obd1 harness that i was gonna swap on since the del sol but I was checking out the plugs on both harness and notice that they are the same on drivers and passenger side except for one plug on the passenger side was a little different, i think it goes to the charcoal canister vaccum thingy. Anyhow the del sol only has 3 plugs on the passenger side, but if i plug the obd2 harness up to the del sol will it run the car? Im running a tuned p28 with most sensors disabled and this is going into a dirt track car so it doesnt have to be pretty or perfect. Any help or suggestions would be great, save me from swapping harness's if i dont have to.

think i found my answer after searching heavily, someone correct me if im wrong.

You can actually use a US OBD1 engine wire harness in a 96-01 integra. You heard me right. 96-01 Integra's all retain a 2-piece wire harness design. Honda thankfully made the break off plugs backwards compatible with OBD1 EWH's.

So, if you can get your hands on any one of these OBD1 VTEC EWH:
94-95 integra GSR
92-95 civic Si/EX
93-95 DOHC Delsol

well got the motor in the car today and used the obd2 harness, car started up but was poping and eventually stalled?? Gonna check the timing t/m but from the way it looks i should be able to use the harness since im running an obd1 ecu

Im not sure about this Im going through the same issue sort of I swapped a b16a3 with obd1 engine harness and obd1 ecu(with an obd1 to obd2a jumper) into a 97 del sol si shell. Even though it plugs in at the shock towers its not working for me
