  • ls/vtec wire harness question

    i just bought a y8 wire harness thinking it would work on my ls/v setup (type r head) the vtec plugs are different and dont hook up to the vtec solenoid...what can i do, replace the vtec plugs? or should i buy another harness?

        also the motor is going into a 92 vx bubble, i have an obd2 ls in the car right now, with obd2 dizzy alt and injectors so i wanna stay obd2....should i just use the ls harness in the car and then run the vtec wires???i bought the harness cuz i know my car is already wired for vtec and i wanted to just use a vtec harness instead of wiring vtec....

          just get a obd1 vtec harness it will be a lot easier and won't have extra clips for stuff that's only obd2

            the only extra plug obd2 has is the cps....like i said the ls in my car is already obd2 and i have an obd2 gsr dizzy and injectors and alternator already so i dont wanna go out buy a harness dizzy injectors, and alternator when i dont have to

                what a mess.
                if you are doing a 1992 it sould not be obd2 at all.
                as far as vtec a you need a power wire from the ecu to the solnoid. then there will be a ground from the ecu to the presser sensor that you can just ground out.

                they you have a a power wire from the ecu to the presser sensor.

                  not a mess at all, i already have an obd2 ls in the car with an obd2, its plug and play to the tower plugs thats why im leaving it obd2 cuz i already have the alt, injectors, and an obd2 gsr dizzy, and rather then spend money that doesnt need to be spent im gonna stay obd2

                      lol such a easy "problem" op, use your CURRENT harness(obd2) and wire the vtec directly to your ecu. not hard at all...no need in purchasing this harness and that harness and spending unecessary money.
