I'll crawl under there and give that a shot. I think something is wrong with the fog light wiring running into my cab, that's why I'm trying to figure out a way to do it out under the hood and just run an after market switch. I'll give the diode under the dash one more shot though. Thanks again.

Well, I finally took 5 minutes and did it. I used about 12" of 14 gauge wire and grounded the yellow wire on the low beams, right behind the headlight. I tapped into it and grounded it right inside the hood on the bracket/brace that goes across just above the battery. Worked like a champ...

Thanks for the heads up. I didn't realize the t-taps were such a problem. I'll just go ahead and take them back then. :) Along with the relay. Man, this mod is getting cheaper and cheaper. Hopefully that tip you gave me will turn my fog lights too. I'll let you guys know. Thanks again.

"Well, it took a while but I finally found the info I needed. As I suspected, the yellow wire at the back of the low-beam bulb is connected to the popular yellow wire under the electrical center. The yellow on the low beam and the purple on the high beam are alternately switched to ground by the...

That's good information. I was talking to the parts guy at our local GMC dealer and he suggested getting the oil changed every 3000 miles anyways. I was guessing that was because I USED to get my oil changed there. I didn't think it made much sense that the manufacturer would install an oil...

JK, I have a dumb question for ya. When I'm hooking up the relay to the wires behind the headlights, do I cut the wires or just put in one of those plastic pieces that lets me tap into them? Sorry for the dumb question, I just want to be sure before I go hacking into wires. Thanks for all...

Thanks. I just PMed you back before I checked out this post. Thanks for all the help. I'll try to get it figured out. Is there a way to do this out under the hood. Something is wrong with the wiring going from my fuse box to the switch. I can jump power to my fog lights inside the fuse...

Thanks FergHoe. Any ideas on how to tie in the fog lights to this set up?

Is there a way to have Highs Lows and Fog lights on? I have an 03 duramax as well that I did this mod to up under the dash with 2 diodes. Now I want to do it to my 02 tahoe. Any ideas?
