my motor is a year 94, its an LS b18b. Since its a 94-95 the motor is an OBD1 if i am correct, but i am running on an OBD2a p75? well my cousin says even tho i am running an OBD1 motor, the harness for the motor is OBD1, but the ECU harness or whatnot is to an OBD2. I got this car back in the summer, and havent really done much with the ECU since i havent done anything major to my car. But is this possible or could happen??? thanks for any input.

EDIT:
O yea this is coming up because i am soon to boost my car, and my cousin was telln me i needed a jumper harness because he has chipped a p75 for me, but then i told him about the motor being 94, and he told me what i said up^TOP.

 

someone most likely used a obd1 to ob2 jumper harness. i would put it back to obd1 for the sake of easier tuning.

 

yea thats what i plan on doing.
