I have a front clip and have all of the wiring harness for the integra Xsi with the b16. I swapped the motor into a 91 ls that was wired for a GSR motor. Most of the plugs are the same except for one in between the other two plugs on the passengers side on the chassis harness. The plug on the body is rectangular with 6 wires and the motor plug is round with 8 wires. let me know what to do. thanks guys

 

you can use the factory harness and just add the wires for vtec: knock sensor, vtec pressure that would be the easy way i think

 

the exisiting wiring in the body is the obd1 wirng for the GSR so they don't match but what is the easiest way to get it right

 

im not sure about that i would say try to find a factory non obd harness for your car

 

man thanks but there has got to be a way

 

Haha, I am in the same situation as you. 92-93 OBD1 b16a motors into OBD0 91 Integras. I believe you can either use an obd0 distributor and ECU, or use your existing parts but get the obd0 to obd1 conversion harness.
