    So here's something that annoys me... having to walk all the way back to the cab to switch on my cargo lighting when I'm loading or unloading something at night. Other manufacturers put a switch right at the back for you to use. Why they don't put a sensor on the tailgate is beyond me.

    Has anyone ever wired in a bed switch that works with the factory system?

    hmmmm if you could find a wiring schematic and figure out if its switched by the ground side it wouldn't be hard to re wire at all. but it might not be switched that way and you would have to run a new set of wires and wire it the same way a house switch for a stairwell operates so both switchs can operate the same lights. ya I think it would be convenient if there was a switch right there as well.

    Just leave your door open a little.

    Al, the Body Controller switches that light, not as easy as it use to be.

    Lousy new vehicles... the BCM does everything. I miss the days when I could add a relay or a switch here and there to change things that bother me. I have a background in computer programming and electronics... one day I will get my hands on a spare BCM and figure out how to "tune" it. ;)

    Ok, so you add a switch.

    The knobs we turn are just user interfaces; you turn a knob, the BCM receives an input signal.

    Just parallel the dome/cargo light switch. As long as the BCM receive a "light on" signal, it will turn on the light(s).

    I'm looking at these LED bed lights from Amazon. Haven't pulled the trigger yet but I want to. Just need to watch more YouTube videos on how to install.

    On my 2011 I added led bedlights on my tonneau cover bows and wired them from the battery to a water proof switch mounted under the bedrail next to the tailgate.
    The only thing I'd change is at the time the vendor I bought from only had red lights, should've waited until white lights were available.

    Having the lights back there is great... especially with a tonneau cover.

    Yup which is exactly why I'd be nice to have. Otherwise, I'll just use a flashlight when I need to.
