does anyone know the correct way to enable the fogs and the highs to be on at the same time? i tried this http://www.bonnevilleclub.com/forum/...ht=fog+disable where you wrap the wire around the relay pin, and then ground it, but that didnt work, maybe because 00+ are different that 92-99 when i comes to fog lamp wiring. anyway ive looked around and cant find how to do this on my 2000, maybe im blind..

Wiring on the 2k'* is totally different than the 92-99'*.


You shouldn't have even attempted that. There are TWO ways to do it on the 92-99, and neither apply to the 2k'*.

You'll need someone with a 2k to chime in.

yea i know when i did it it was one of those things that i said to myself what the **** was i thinking, but it turned out fine luckily..ill just have to wait until someone chimes in, theres got to be somewith a 2000+ thats done this.

Oddly enough..I don't remember anyone that has. I could look at the schemaitc..it would be later in the week though.

Archon....where are you?

Hey, I did this just a few days ago..The fuse box by the motor has relay number (29)fog lamp, took it out and rapped the wire around pin number (85) to ground..it worked with the highs on. The only thing is the fogs stay on, you can't shut them off with the dash button. They do shut down with the ignition off. I only left the wire on for about 10 minutes with fogs and highs on to observe, since I was not going for a drive i removed the ground..
I'm just thinking about Willwren'* comment.
Willwren, If something was to go wrong with what I attempted , would it have happened wright away?

Been a busy week...daughter got married Saturday.

I've been briefly looking over the schematics as I have time for an "all in one" solution, where the fog lights are still switchable, without having to do too much rewiring. What Rodbonneville posted sounds as if it should work ok if you don't mind them always being on. I haven't checked thoroughly on it, but any problem should have shown up right away. Viper...are you good at reading schematics?

thats the same relay i used, i just put it on the wrong pin, although i would like to be able to shut them off..

I dont have a lot of experience reading them, but im pretty good at looking at things and figuring out how it works/what it means.

Yeah I feel the same way..I like the option of shutting them off at dash.

alright i just had this idea.

i just helped my brother install a headlamp relay on his 05 silverado, that enabled the highs and lows to be on. it consisted of a relay and fuse that tapped into the 2 hot wires on the drivers side high and low beam, and then there were two wires that needed to be connected to a power source.


what would be stopping this from working the same on the fog lights?? from my understanding the way that relay works is when the highs come on, the current form the high beams close the relay and send power to the lows. maybe there something im missing, but why wouldnt that work on the fogs in the same manner?

one thing i dont understand about it is how the works on the passenger side as well since it only hooks into the driver side light..

The headlights are probably wired in parallel. That would allow power to one headlight to feed both. Ours is a bit more complex, with the daytime running lights putting the lights into series. Also, the DRL relay provides the ground for one of the high beams. I'll try to look over the schematics over the next few days (hopefully) and see what I can find out.

In the meantime - here'* a link to lighting schematics.

Edit - However, if you are not adverse to cutting and splicing some wires, it would likely be a lot easier to add an external relay to accomplish the task. Before we do that, I want to make sure it won't cause any voltage feedback issues and put you back to the beginning of your other thread.
