'Nother light issue.

My tail lights and turn signals in back work just fine. However, I have discovered that my trailer connector plugs don't have tail lights when I plug a trailer in. Both the 4 and 7 prong connections don't work. I know the four prong is damaged and needs to be replaced. Is there a common failure point that would cause this that anybody has dealt with in the past?

The ground? If it mirrors the F150, the screw is drilled into the frame rail right about where the harness plugs meet.

I have seen lost lights reappear when the built up grime is cleaned out.

I dropped the spare tire to access the wiring and noticed the ground seemed a bit iffy. I'm hoping to get time to work on it tomorrow.
