I talked to another member on TYF (the one I bought the fog switch from). He has a 95 tahoe and said that the pigtail for that switch was already there, just tucked away in the dash wrapped in green foam stuff. I'm going to look in mine when I get it back and see if I have the same thing. That would be nice.
If I'm right, SUV's were the only ones with fogs in the bumper from the factory, right? The Tahoe Limiteds and Z71 Tahoes had them, right? Didn't all the sport trucks had them in the valence?
If your Tahoe is optioned, you most likely have the pigtail for the vertical fog light switch!
And yes, the Z71 tahoes and limiteds where the only GMT400'S to have fog lights in a diesel bumper from the factory. They had a factory push bar as well as a colormatched grille and bumper.
The trucks with the sport package had factory fogs in below the bumper in the valance.
And the 99-00 Escalades and Yukon Denalis had them factory fog lights in the bumper cover. All the Denali's and Escalade's had the vertical style fog light switch.
The 454SS trucks also had factory fog lights mounted below the bumper in the valance as well, with the switch mounted to right of the steering wheel, mounted below the HVAC Controls in the far left knock out plate.
