Visit the dealer's parts department to see if they have a kit for your truck. It will have all the correct parts and wire harnesses. Be aware that once the installation is done, the lights most likely will not work until you have the radio reprogrammed by the dealer, and they don't do that for free. It's one of the many tricks GM designed in to cost you more money after the sale. Many other manufacturers have done the same thing. Until the Body Computer is programmed, it won't know there's fog lights on the truck so it won't try to turn them on. To prevent you from replacing the original radio with something different, the engineers cleverly built the Body Computer into it.
There is a chance the lights will work without visiting the dealer. On Dodge trucks, the Body Computer learns the lights are there when you turn them on, so no manual programming is necessary. If you're lucky, yours will do the same thing.
Also, there may be no extra wires on the new headlight switch. With the new "CAN BUSS" electrical system, all switches are little computer modules. That adds a huge amount of complexity and lack of reliability to all cars and trucks since the early '00s, but all data is transmitted over two wires connecting the switches and computers. You may just need the head light switch with the extra fog light switch built in and no additional wires to it. If it's like the Dodges, the connectors will be hanging next to the fog light openings already so you won't even have to run that harness. Just plug the lights in and you're done.
