    I know i have one in my truck and the connector is somewhere in the headliner. Has anyone got acess to this? Where is it? I have a 2005 2500hd extended cab by the way.
    Thanks for any help.

    There isn't any connector. You have two blunt cut wires, one green and one black. They usually are taped to the relay harness which is above the front map lights.

    It's somewhere up there. The wires are taped up as the trucks roll along the assembly line, and seems to be no exact location from truck to truck. It's above the headliner tho for sure, look for a brown and a black wire

    My apologies, I forgot they changed them in 2007. Here is the excerpt from GM:

    A couple of threads (or more) here have a link to the GM Upfitters site. They have a big list of stuff by year and model. I found two pages, with drawings, under "2003 & Beyond Light Duty C/K Full-Size Truck Electrical."
    Does yours have the push-button switch on the dash, just to the right of the heater/defroster controls?

    Yes it has the button on the dash . I just wanted some insight on where the wires are before i start taking apart the headliner.

    Okay, that Left-Hand B-Pillar thing should get you to where you need to go. The relay is down toward the bottom of the pillar.

    Depending on what you are doing, you don't have to drop the headliner. Just remove the dome light and you should be able to get the wires.

    has anyone else had a problem with the switch NOT working when you hook something up to it. I ahve 2 identical 2500hds, ext cab, and when I wired up the first one to my whelen bar everything worked fine. Today, I'm wiring up the second truck the exact same way, and not getting any power at the light.

    What type of light bar are you using?

    I'd go for the "easy" stuff first:
    1. 30-Amp SEO 2 fuse, in the Underhood Electrical Center
    2. Something disconnected from the relay, which is located in the left B-Pillar.

    Also, what years are the trucks?

    Ok, as Maine Train said, check the SEO2 fuse underhood.
