7 pin Trailer Charge and Reverse
I have to wire up my Expedition from 4 to 7 and I'm wondering about the charge line and the reverse line. Does anyone use these? It's a long run from the relay up front to the trailer battery. Not sure 10 awg will get any charge to the battery. Also my TT does not have clear reverse lights. Guess I could buy a set of cheap driving lights.
