I've searched a little bit but came up shy. Looking to put OEM fogs on my NBS 00 1500. My question is do I already have the harness like the nnbs and just have to install the switch and relay or does it require the entire shoot and shabang? I'm not electrically or automotive ignorant either. Looked to the plug to be zip tied and didnt find it. Didn't try to tear apart looms or anything though.

 

You will need to buy the kit.

If the truck was wired for them, you find them right near the frame rail behind the bumper.

It was sold as a kit but a since been discontinued for the 99-02 style

99-02 style truck

If you have a 2000-2002 model tahoe or surburban with rear window wipers you will need part number 15735839 fog lamp switch in addition to this kit, as the fog lamp switch included in this kit will not work. (BCM must be programmed by your dealer to recognize the lamps so they will function)

1FastBrick got it right on. I was lucky enough to find the 12495928 kit on ebay new from a guy who had sold the truck he originally purchased it for. It was really not that bad to install. Plug and play for the most part. Although there is a catch - if you want to use the factory kit on a 99-02 (this does not apply to the 03-07 nbs trucks) truck that did not originally have fogs as an option from the factory, you will have to have the trucks Computer reflashed to recognize the lights and provide power to them.
The kit included lamp housings, hardware, bulbs, harness, relay, switch and instructions. Overall it took me about three hours to install. If you cannot find the kit on eBay or online, the individual parts are available on eBay and elsewhere online.
