Sometimes they did partially or fully pre-wire trucks for fogs, either omitting some wiring, relays, fuses, etc.
I've had tons of guys with the same situation: "i have the plug behind the bezel but no switch" or "i have the plugs behind the bumper but no plug behind the bezel".

You can try to determine if you have all the necessary wiring & if you're lucky, you'll only need a couple parts & a bezel with the fog switch opening & bracket... or if that's too much work (it can be a PITA) you could grab one of my oem fog wiring kits.

My kits bypass all the factory wiring & will allow you to control pretty much any 12v light or accessory with a oem switch on the bezel.
