Hello, Brian!

I realize this is a very old post and you may not be active on this forum anymore, but..
My left license plate light is not working (tried different bulbs) and I suspect there might also be an issue with the wires inside the wiring grommet.

Before taking it all apart, do you have any information, which wires are in the left wiring grommet and which ones in the right? Which license plate light wasn't working correctly when you found the broken wires in the right grommet?
