2019 Bighorn Bed Light Power Solution: The Curt 55384 USCAR Connector is designed to supply a 4 Prong outlet, it also acts a as pass thru for all towing wires, including 12v Aux. This 12 Volt aux is used for Battery Charging, etc. This Aux port is hot all the time Via Fuse Box. A simple method is to tap into the Aux wire on the Curt Connector and running power to which ever lights/switch you choose. Saves running a wire from the battery or modifying existing wiring. I mounted LED Light strips and installed switch in plastic plug that would house OEM Lights in Bed.
It would appear that some trucks may not have the Aux power pin energized, mine did, not sure why. This can be easily checked with a meter, my trucks Aux pin was at the 1 o'clock position.
