can someone tell me wich harness to use to put a obd1 ls into my 91 civic si. ive heard you can use the si harness, but ive also been told you can use the ls harness except for the 2 dizzy plugs. i cant see how the ls harness would work because the plugs that wouls plug into the car are different. can someone help me out and explain what i should do. i really would like for my car to be up and runing again.
