        OPR fuel injector wiring

        Brilliant, as advertised. This might be your answer to the pure torture of misbehaving sensors.

        Much needed

        My '88 injector harness had several broken plastic clips and was getting very brittle. This is exactly what I needed!

        Looks OEM

        All of the connectors seem to be OEM or equal in quality, and the wiring is wrapped just like the original. I haven't installed it on the car yet but it looks identical to the original harness so I don't foresee any problems.

      why wont it fit 86? looks the same

      • The wiring harnesses may have changed slightly between the 86 and 87. Something in the electronics may have changed slightly which makes this harness not compatible with a 1986.
