I am going to use your advice, Tom and Jim; I don't know the wire size going to the battery from the tow v. I think it goes first, into the control unit, under the seating area, and then back out to the battery, up front. can ( or should ) I run a wire directly from the trailer 7 pin, to the battery? I have changed, all interior and exterior lights
to led. I have installed a 12v outlet next to the electric control. I would rather use the refer, on 12v, than gas, while driving!
