    Does anyone know where I can tap into a constant, non ignition switched, 12VDC power in the rear bumper area section? I have checked the hitch connector and the only time power is present is when ignition is on.

    Otherwise, I would have to either tap somewhere in the engine bay, or inside cabin and also, I am trying to avoid running a long wire all the way to the rear bumper.

    Truck is 2016 Tundra CM--thanks

    What about the bed lights up near the center brake light? Any way to tap into them?

    I thought about that already however, that would still require a wiring run from the cab somewhere and the 12vdc will only activate when you step on the brakes...other than the park lights as a possible source, but requires turning on park lights switch...

    I don’t think there is a solution as I have checked every wire/circuit back there with my fluke DVM to no avail & found 0 volts DC...

    Unfortunately there is no constant 12v source at the rear of our trucks. Running a wire forward is fairly easy though, I do it all the time at work for truck caps. I use 14 gauge for wiring dome lights, wrapped in 1/4" split loom and run up the inside of the driver side frame rail and fused at the battery.

    sounds like you guys know what u r taking about. However I thought there is +12v available in the 7 pin trailer connector.
    It is auxiliary +12v on pin 4???
    Not sure where I read that but something to check if you have the tow package. I will check it one of these days.

    You're correct, there is 12v power at the 7 pin but it's only powered when the ignition is on. OP was looking for 12v that's constant to view a back up camera without the truck being turned on.
