    the Gauge indicator is powered through the neutral safety switch.
    It tells you if your in P R N D 3 2 1
    Make sure thats plugged in, for some reason on mine N D 2 1 don't light up.
    Good luck..

    here is a pic of the switch, it bolts to the tranny.

    I didn't hook the 5.3 oil pressure up because I was under the impression it wasn't a must. I just hooked the factory oil pressure up into its place.

    Which wire did you hook the neutral/park wire to on the neutral safety switch?

    Not only is it plugged into the nelson harness, he tried plugging it to the old harness, then he took the old part off the original transmission and plugged it into the nelson harness, then into the stock harness....nada.


    So it would seem there is a problem elsewhere.


    Something else I noticed, the solenoid wire either from the stock harness or the nelson harness, neither get 12v with the key all the way forward (or to engage the starter)......its gonna end up being something simple thats gonna pis me off.

    Like maybe the power lead that runs to the starter relay has been taken off or the fuse popped?
