I need to know if an OBD1 Integra engine harness will plug into a 97 OBD2 main harness by the shock tower?

Or would it be easier to use the stock OBD2 harness?

The car is a 97 civic coupe with an OBD1 B18 non vtec.

The wiring harness is a mess and all hacked up. I need to replace it, but just need to know which will be easier.

I will be running an OBD1 P75 ECU via jumper harness. I do not have emissions to worry about so that is not an issue.

Need help quick. Thanks.

 

You have to use a '96 - '98 Civic engine harness. The Integra harness is a 2 piece design like the '92 - '95 civics and '93 - '97 Del Sols. '96 - '00 civics are a one piece design that goes all the way back to the ECU. Remember to use a '96 - '98 harness as they are different than the '99 - '00 harnesses.

 

Yeah I talked to my buddy last night and found that out. That sucks. But oh well. Not my car. It for a friend. He bought the car with a OBD1 B18 motor swap and it is a wiring NIGHTMARE!!! Everything is cut, spliced, electic tape, and butt connected together. The car does not idle very well, but that could be because of the ECU because its a P06 chipped with a d16 supercharged program on it.

It needs to be re-wired with a good harness.
