Hello guys, I have an issue with the tail lights on my bike. When I bought the bike the rear fender and facia piece had been replaced. The tail light assembly was plugged into the output side of the facia light assembly, but no wire going into the input side. And my bike doesn't seem to have a wire that has a matching plug for the facia input connector. Do I need an adapter wire? And if so, what part number is it. The local HD shop was no help.
