hello, I am pulling a 95 obd1 gsr swap out of a 95 civic ex, and swaping it into a 98 civic ex. My question is are thier any parts i can reuse off the 95 civic like engine harness the one that goes from the shock tower to the ecu, or anything that comes to mind. thanks a head of time.

 

you gotta use your stock D series harness..if your keeping it OBD1 then you need a jumper harness for the ecu to OBD2a-Obd1...then you would need a obd1 ecu...if you keep it obd2 then you need to add a couple sensors or else you will throw a code

 

to keep the wiring at a minimum you are going to have to reuse the OBD2 injectors. You will also need to just wire up the IAB's, either repin your distributor or get an adaptor harness, and get an OBD1-2 ECU harness if you plan on using the P72 or P28.
