That's my underglow controller, change pattern, speed, brightness, color, etc.

 

i just bought some aftermarket fog lights for mine off ebay. they were very affordableat $63 and have a complete wiring system with installation instructions.they're being shipped to me as we speak so iwill have them installed in a week or so. i'll try to get some pics up when i have them in.if they look/perform well, i'll get you the link for them on ebay.

 

The only problem with the aftermarket Fog Lights will be the mounting. The Factory Fogs are held in place by a 3-legged, tripod-like, mount for which there are slots and guides on the inside of the Bumper. There's not much around the Bumper cut-out for the Light to mount too. There is only the pre-drilled hole GM provided for a fastener on the Bumper of the '04 LS Monte.

But, with the Factory Mounting Brackets, installation is a breeze.
I needed to buy, from GMPartsDirect, two OEM Pigtails that fit the Bulb Socket.

Thinking that I was going to be able to use Factory wiring. I bought an OEM Fog Lights Switch and Fog Light Relay which I do not need.
The New Switch and Relay are For Sale - Both: $25.00 - Includes delivery in a small, padded envelope.

 

That's a whole different Switch from what I have in my 04 LS. That looks nice.


With the redesign in 2006 of the Monte, it and the Impala got a different headlight switch versus the '00-05 Montes.

You can turn the fog/driving lights of the '06/07 Monte on while just the daytime running lights areon. The '00-05 Montes you can't. (as far as I know)

I tried doing this with our '03 Pace car. The fog/driving lights wouldn't come on without the headlights being on.
