Recently bought a 2004 Trailblazer LS. I am looking to get the fog lamps installed. I found the fog lamps but can't seem to find the wiring, switch and relays. Any ideas where I might locate them?

Check the fuse box underneath the hood for the switch for the fog lights.

Are you saying that the TB is prewired even as an LS? The dealer suggested that to me and all I would need is to buy a new light/fog lamp switch for the interior for 82.00

I'm not necessarily saying the LS is prewired for non-existent foglamps. In fact, I don't even know about that for the LS. I own an LT. But I do know that all electric work goes through the fuse box.

I own a 2004 LS and mine does have fog lamps on it. I do believe that it pre-wired for fog lamps but you will need to buy the switch that is located next to the head lights controls. I do believe that you will need to cut out the holes in the valance as they are covered by plastic but I could be wrong about that.
