I did a search and couldnt find this so figured i would ask and see if anyone knew the answer. I just bought some tow mirrors. They have the LED spotlights and my XLT does not. I know there is a switch inside the cab to turn them on. My question is i am wondering if it is possible to make those work since my current truck does not have them. Is it just the switch i need to buy and the wiring is already there or will it be necessary to have it wired to make them work?

Any help is greatly appreciated.
Thanks in advance!
