    NNBS wiring harness

    Looking for a Gen4 harness. Not sure if mine is bad or not, looking for one to swap out to test and see if the harness is what is causing my engine electrical issues.

    Loses power or signal to the pcm intermittently which causes a jerking in the engine and the tune to jump in and out of closed loop performance while cruising.
