Wiring for truck bed lights

[Tony H]

I am planning on putting truck bed lights under my Tonnele cover, I was wanting to hook them up to the cargo light that has a switch in the front of the truck. My questions are where is the wire, On the driver or passenger side of the vehicle and what color is it. Also these Paul around 10 A will that be too much for that specific circuit?

Just found out they the lights use 72 watts so at 12V I think that is 6 amps.

I can help with this one. See this thread I created. I installed back-up lights using the same cargo light circuit.

See page 11 for my finished photos. You want the red wire in the far right plug in the junction box which sits just above your spare tire. If you don't have the plug there, you may be able to tap into it from the back side, or just buy the GM bed lighting kit which should give you all the wiring and lights you need.

 

I have some more photos of the junction box and wiring in my gallery:

I found what you were talking about and saw the photos, one more question how did you add the wires to the plug?

My plug has no wires in it

I split the loom open and tapped into the wires going to that plug. I'm not sure what you could do if you don't have a plug in there. I'd try to find the wiring kit that is an option on these trucks (came with mine)

Can you test to see if the terminals are getting power? I think those should be plug and play, but maybe need the truck to be programmed if it didn't come with bed lights?

I did test and had power (tough place to test) I found the one harness and think I’ll just buy that for only $26.00. Thanks for the help
