This should be fairly easy. You are missing one circuit. There is a single brown wire going to the rear that feeds each taillight and also the license plate lights.
This same brown wire also feeds the front lights. That means the fuse is good, the switch is good. It runs all over the truck. Find the brown wire at the rear, there is a wiring plug back there on the driver's side rear. Get a testlight and poke the wire and see if you have voltage there with the running lights on. If you do not have it, work your way up front to see where the problem is. If you have it, then it's probably a problem at the plug itself or some spliced trailer wiring.
