Bed lights wiring question

[Marcross1009]

So in researching adding bed lights to my 2021 3500 tradesman, I was looking for the wiring to see if I could find wires from the cargo lights to tie into. I found a plug by the end of the bed on the driver's side that has the black wire and white with tan tracer wire, my question is does anyone know if these wires are switched with the cargo lights, or are these wires that need to be activated with alpha dog?

Here is the plug unplugged, the top right wire is the white with tan tracer, 4 pins to the left is the black wire, I tried checking for power at the pins but did not succeed in getting any reading on my multi meter.

If I can't get confirmation on these wires, I may just tie into power through the 5th wheel plugs in the bed, I found a light strip kit with a pin switch that should do but I'm not wanting to drill holes if I can keep from it.

That looks like the Aux camera prep plug. Do you have a 7way with 12 pin plug in the bumper/bed? The bed light wires travels back to the front of the truck to the BCM plug. That way the light are powered up by the exit lighting, as well as have switch capability from BCM.
