I'm Bruce, I have a 2017 Expedition with an Eco-Boost. I would like to know if anybody has any information on if the trailer wiring harness has the 12 volt battery accessory wire for a camping trailer already in the harness. I already installed a 7 pin trailer connector, and factory brake controller, ( that works perfectly, thanks to this forum ). I understand that it is a matter of a relay, and a fuse, ( also from this forum ).
