I had this same problem with mine. New repop lights and the 7-wire signal from classic parts. I had to add a ground wire from the back post of the tailight housing, to the taillight bracket.

I ended up soldering it on and it looks much cleaner now. Some people run that ground wire from the housing to the bed/frame.
