I have the same truck as yours, Tradesman, no fogs. Looking to run the OEM switch like you've done here, I have plans for the Aux/Upfitter switches. I am looking to run the same setup you've done here just with another brand of aftermarket LED lights is all. You show part # 68156061AD for the switch.I guess the first questions would be does your truck have OEM fogs and are they LED?
If you have fogs and they are halogen you can plug them in and update your BCM to reflect that you now have LEDs installed. If you already have factory LEDs it's just plug and play.
If you do not have factory fog lights you must decide how you would like to switch your new LED fogs - OEM headlight switch like I am doing, one of your six auxiliary switches or separate third parts switch. Third party switch is easy - find 12 Vdc and send it out. Auxiliary switches are quite easy and look good also but they are not triggered on or off by low-beam of high-beam lights. Running through the OEM headlight switch is the most difficult but the cleanest. Lot's of choices.
