can i use that harness on a obd2a gsr motor with out any problems? btw shell is a obd1, just use p28 or obd1 p72?

 

The B16A2 harness is one piece while the OBD1 harness is two piece. For plug and play you want to get an OBD2 GSR engine harness to make it plug and play. You'll still need to run VTEC wiring, knock and IAB to the ECU from their respective sensors. Either P28 with P72 basemap or OBD1 P72.

 

k thanks im just gonna use my obd1 ls harness.
