alright well i got a 2001 ls blazer 2 door.i feel like its fully loaded it dont got bose or anything no leather but its got the factory tape/cd and sunroof ,but i removed my dash and on my light switch it has a pig tail where the stock fog switch would be.but im buying a envoy bumper and im wondering if i got fog pigtails in my bumper somewhere since i got the harness and fuses for it....HELP ME

 

I don't think the pigtail will be there for the fog lights in the bumper...also keep in mind that if you get a switch with a fog light button, that button will not work unless you get the bcm re-programed by a dealer.

 

oh damn thanks man ill just do my own set up then.

 

My jimmy has the plug behind the headlights, and all the fuses and relays in the fuse block. I was thinking about getting headlights with fog lights built in.
Are you sure the computer needs reprogrammed? I'm too ADD to follow the wiring diagram without getting distracted., but I don't remember it being anything but strait through wiring.

 

The wiring for the fogs goes through the computer, and you would need it to be re-flashed to a vin # that came with fogs from the factory.
