I have a 2000 GMC Sierra and would like to add fog lights?
Is the wiring already there to do this?

If there is a switch in the dash, I would look at the grill or bumper for a harness, if no switch, you have to wire it.

Probably.
But, to make the factory fogs work, you have to have their function turned on in the BCM. The computer will not recognize them if you ised the factory switch.
