ok im a little confussed on which engine wire harness i can use for my car. Its a 1998 LS that has a B20 in the car right now. I have a Built LS-Vtec that im swapping in this month. I know i can use the harness that is in the car. But i also have civic ex harness laying around could i use that and not have to wire in Vtec or just us the harness on the B20 and wire in Vtec. I have a chipped P28 ecu.


(im trying to avoid wireing in Vtec)


this might be a dumb question but integras are new to me. Also i can use a diff. harness so i dont have to wire in Vtec that would be helpful as well.

 

Are you keeping your motor obd1 or obd2?

 

To wire Vtec is only 3 wires, its not that hard and are you obd1 or obd2, thats what we need to know first.

 

What year EX harness? If its 96-00 you can't use it. If its 92-95 you'll still have to wire VTEC because the cabin side of your harness doesn't have VTEC wired. Its really easy to wire.
