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...

^ this. Truck side, all modern 7 pin connectors are the same, so just look for one of those wiring diagrams, or break out the test light and do it the old fashioned way.
On a similar note, if you are buying a pre wired 7 pin plug to adapt to the camper plug so you don't have to modify the truck, be aware that some of these parts store plugs are NOT wired correctly. Had a guy grind off the 7 pin on a new trailer at work and one of my supts bought a pre wired plug to splice back on and only 1 or 2 of the standard wire colors matched properly. Had to test light it to get it wired up right.
