You can use the Pacer 3rd Brake Light Logic Module # PP20-702 if you're tapping into the tail light wiring to get the signal on your camper shell. If you wanted to tap directly into the 3rd brake light circuit on the truck cab's 3rd brake light, you can also do that and you wouldn't need to use the Pacer module.

In order to get power to the dome light, you can do one of two things. If the dome light has a switch, you will want to run a wire straight from the vehicle battery so that you can turn the dome light on regardless of if your truck is on. If the dome light does not have a switch, you'll want to run power from one of the interior light circuits so that it is only on when doors are opened or the interior lights are turned on. Currently we do not have any specific information on where an interior light wire would be located, but you could attempt to trace the wires from the interior lights or use a fuse tap to tap into the fuse that controls the interior lights.

If you don't have a circuit tester like the # PTW2993, you will need one in order to correctly identify some of the wires that you'll need to tap into.
