ok man one more question....Since im running the jdm obd2a ecu with the swap and using a obd2b to obd2a jumper harness, do i still have to pinout things in the ecu wiring?
You will have to run wires for the IAB solenoid, as the civic harness won't have that built in. Also, you may or may not have to run a knock sensor wire. On my 93 civic I did.
What and where is the IAB....i know once you tell me im feel stupid
Your stock harness wont be wired for the iab, so the jumper harness won't solve that problem. Just run wires from the plugs strait to the pins on the ecu.
