I have a obd2 car which im going 2 install a obd1(gsr) motor but I dont want to use a jumper harness. I that the inject plugs are different,the dizzy would have to be repinned, alt plug , and others should i use the obd 1 harnes or the oe

 

you would prob need to do more work then just repin the components..you would need to switch around the wires at the ecu also if you dont want to use a jumper harness...the injector plugs i dont think you would need to switch those to obd1...the dizzy you would need to switch to obd1...the alt. you can still use her obd2 alt. as long as you get a belt that fits..

 

thank for the insight more info is welcome
