I bought this 99-00 SI shell, and the guy gave it to me with a b16a obd1 engine. I have a obd1 ECU, a obd2b to obd1 jumper harness and a obd2b engine harness (came from manual VTEC si 00) What plugs do I need to change so the harness will fit on the obd1 engine? Should I buy a new obd1 harness (impossible to find one here)? I really suck at wiring..
