4 headlight mod

[rabt]

the high beams in a 1999 - 2002 are one ofthe few things that switch on the positive wire with out a relay ..... i would put a relay in so the fog lights would come on with your high beams

Silveradoking...the 100.00 is to tell the computer that fog lights are installed. All plugged in with all factory wiring and switch nothing happens when you turn them on.

Wow, thanks a lot for that. Seems very easy and makes a lot more sense now. Also, by using a wire tap it seems very un-doable should the need arise.

[BlenderWizard]

Chuck, Firehawk, Walbern, or anyone else who has tapped the ground, what gauge is the "yellow wire?" I'm about to do the mod, but I want to make sure I get the right gauge tap.

its a 16 guage i beleive, but lemme tell you right now dont waste the time with the relay, just tap into that yellow wire and ground it good, by far the best mod yet, ive done...took all of 5 minutes

Yep, it was 16 gauge, and I just did the mod. Looks and works good.

Does anyone know how to do this on a 99 Tahoe?
The circuit panel looks different and the relay described is for the horn, and there are no yellow wires.

Did you check the Tahoe section? Someone in there is bound to know.

I want to do this mod this weekend. Before I start tapping wires, I want to verify the correct yellow wire.



I am assuming it is the yellow wire in the upper right corner on the grey-white block. Someone please confirm.

Yes, simple and cheap. That is the correct yellow.

[BlenderWizard]

Yeah I tapped mine with yellow wire and tucked it into some conduit on the way to the grounding nut/stud... barely noticeable untill I get behind you and blind your ass!

[chuck16]

I wonder if the 2005/6 models will offer this feature. It seems silly to me to not have this as a standard feature. For something so easy it should be standard. Such a great mod....

[BlenderWizard]

Hey, Chuck, what did you have to do to keep your fogs on with your high beams?

[jethro_3]

My '05 does not stay in the 4 light mode. If you pull it for passing it will go to all on but pops off when you let go. I beleive the '04 and up is the reverse polarity switched and thus takes different wiring to make it happen.

Threw away the stock Fog Light switch. Well Actually I kept it but, I wired the Fogs on my own wiring. I used all the factory wiring from my relay to the lights so that it looks pretty stock. Then I wired a switch in just below the blank spot where the Cargo Switch is. My Truck didn't come with the fog lights so I bought them after wards and wired them my own way. I also wired them so there was never any chance of leaving them on by accident.

I was sadly disappointed that they don't throw a lot of light. I had Bosch Pilot Driving lights on my last vehicle and I miss them. I can't wait for these to burn out or somebody who wants them cause I'm ready to chuck'em.

Think I'll go with some Piaa's or something like that...
Hope that helps.
