I was wondering if someone can help me out. I have a B18C (OBD2) and swapping into a 98 Civic EX. Do I use a civic or integra wiring harness?

 

you can use your stock harness i have 98 dx with b18b swap wit gsr tranny axels etc all i had to do was buy motor mounts and change around a couple of plugs on my harness u wont need to u just might need to find the ecu pinout diagrams for ur car and the gsr to verify the pins on the plugs are the same then ur all set

theres the ECU pinout and some other information your going to need for the swap. You have to use your stock wiring harness

 

Thanks for your help.
