Ok so I just put in a new rest lamp harness and my rear license plate lamp doesn't work. Where do I go from here? Tried two bulbs and both looked brand new and filaments were intact. My running lights on the rear work though just fine.
so much of the time your ground isn't going good.
Always check the ground connections however, wherever first.
Then re try. Still not going? Get Volt meter out. Check power at outlet next.
sounds like you have power back there already.
