ok i am currently doing a gsr swap into a EG hatch, so far no probs.

BUT

i am concerned about the wiring becuase its a 98 motor

and it just came to my mind that the dizzy is obd2, so, if i use the obd2 engine harness, will i have problems wiring it up?? an obd1 ecu will be used, for obvious reasons, but i know ALOT of plugs wont be used, does anyone see a potential problemw ith this???
