ok haveing a bit of a dumb problem i drive a 1997 civic si coupe and i swaped a jdm b16 sec gen in and i went to plug the ecu harness into the computer and they dident fit so i need a conversion harness which one do i need iv searched the past 2 days cant find the one iam lookin for motor is obd1 and car is obd2

 

You need an OBD2A to OBD1 conversion harness. The first "OBD" listed is always the car it's going in; the plugs. The second "OBD" is always the ECU that you're trying to use. '96-'98 is OBD2A, so that's where you get the "A" from, instead of it being OBD2B.

 

ok thanks alot
