Asking anyone out there that knows, is there a way to get the bed lighting to light up with the dome light?

 

Just splice the bed lights to the domelight wires. I assume you are talking about the light on the cab?

 

When I turn my bed lighting on the upper exterior dome light also comes on.
Unless you're referring to something different?

 

No I was referring to the lights built in the back corners of the bed by the tailgate. There's a button on the left side to turn them on (it also turns on the cargo lights on the cab). I was just wondering if there was a setting that ties them to the cargo lights so when I unlock the truck they would come on with the cargo lights.

 

On my truck, the cargo lights always light up when opening or closing the truck at night (along with the parking lights), even with interior/exterior lights turned off. But the lights in the bed do not turn on. Those only turn on with the bed switch. I imagine you could rig it to the cargo light, but it wouldn't be worth the trouble, to be honest. You'd need a wiring diagram to see which wire(s) to tap. Good luck.
