New 2017 F350 wiring to Lance plug??
We picked up our new 2017 F350 yesterday. I pulled the lance plug from the bed of the old truck.. Now I need to know which wires do what on the new 2017 F350 wire harness so I can tie this plug into...

I was told by the guy who installed my Lance plug that all they do is get the truck side plug and plug it into the trailer wiring harness, all except for the 10 ga wire that they run directly from the battery to power the frige.
So, all the other wires just wire into the 7 pin standard towing harness.
Me thinks I have heard that before. They use the factory plug wires for everything except the two 8 gage wires they run directly to the battery. I assume they fuse the hot side at the battery.
We plan on getting an 2018 F350, so I will have to figure it out sooner or later. I want to wire this new truck with adequately sized wire for the frig to operate correctly on 12v going down the road.
