sorry, I am not getting 12v to the 7-way trailer plug at the rear of the truck.
My dad is pulling a fifth wheel camper and would like to the ability to re-charge the trailer batterys when hooked to the tow rig. The manual states that the wire harness for the electric brake controler is supposed to have a "mega-fuse" along with it for this purpose. His didn't have the Mega-fuse and we need to know what size to go buy.
