Figured it out!

Wow this is an old post, but I'm looking to do this same mod for my 2002 yukon denali xl. Is the mod the same? Help plz

It is possible. Look in the NBS section for the 4 High mod.
I did this mod all those years ago and it is still running strong with no issues whatsoever.

I wired my fog lights like the photo below and they work perfectly. They come on with the headlights and stay on with the high beams. I've not had a problem and this is the second vehicle I've done this with. I just used a single piece of wire with no diode. The photo is the fuse box from my D-Max but it works exactly the same way with my 2014 Suburban.

Yeah Sophomore its pretty easy, but I would wait like you said until you get HIDs, or LED fogs (like me) so it matches.

Did you just buy the bulb? I don't really wanna buy a whole hid kit

Would it work on a 2004? Or just the newer style?

Good question and that is one I can't answer because I don't know. My D-Max was an 08 and my Suburban is a 14

Would it work on a 2004? Or just the newer style?

There is a write up in the 00-06 for your body style

The light they put out is pretty much useless but they do look good!

Actually my fog LEDs made a huge difference. Right side is the LED, left is stock.
