Your slide-in truck camper does not have electric brakes so the blue brake circuit wire from its 7-way connector is not used. All other lighting functions as well as 12V auxiliary power will be maintained on the other circuits. Please refer to the linked photo for the standard wiring/function configuration for RV-style 7-way connectors.

I have a 2012 Ford F250 and a 2002 Lance Slide In, I have the wire supplied by the Lance Company to wire the camper to the pickup, but have no idea where to run the wires and how to figure out the running lights from the turn signals. Is there a place to get a detailed plan for such an installation?

To splice in the pigtail wiring from your Lance harness, your best option is to actually test the factory wiring on your F-250 with a circuit tester. You'll use the tester to determine which wires behind the tail lights carry power with each light function activated on the truck (running lights, turn signals, etc). Unfortunately I don't have a diagram available of the truck's factory wiring configuration.

The wire for connecting the camper hot and ground wires are 8ga, could I use 10ga safely? Thanks

Lance does recommend sticking with 8 gauge wiring all the way through for their harness, but honestly using slightly smaller 10 gauge # 10-1-1 shouldn't cause any issues. This is still pretty thick wiring that I can't imagine would prevent getting all the power you need to the camper.
