I just purchased a 96 integra with a b16a2 motor from a 99-00 civic si motor. My issue is that they left the stock ls ecu. I've purchased a p2t ecu but will need a obd2a to obd2b harness to have it installed in the car and i am worried about the immobilizer and that the ecu will not work on the car. So does anyone have suggestions or solutions for my issue? Btw, the ecu is straight from the dealership.
