white/black = ground
There is a gap between the bedcaps and the bed (rear metal upright) large enough for 3 wires to fit. You can fish them out from inside the tailght.
For quick disconnect capabilities you will always have a connector there (so it will as clean as your imagination its just wires) . If you don't have a "quick disconnect just get a 4flat trailor harness loop and use it (they come in 48'' lengths).
I hope this helped.
I bought a flat trailer wire set so I could disconnect it when I wanted to remove my topper.
I am sure that your black wire is ground. I am pretty sure that your red wire is brake. I am guessing that you have a dome light and that is the striped wire. You can run the dome lights off the green wire, but your dome will only work if you have your lights on.
