Just bought a 2012 6.7 king ranch F250. Question is , there are four Aux light switches under radio. Do these have PRERUN wire etc. I want to hook up a light bar on front bumper. What is needed to hook to one of these switches. This is my first truck with these preinstalled switches so I'm at a loss.

Thanks

 

They are already pre wired under l e ft side of dash. All you need is a hot wire hooked to the, and a grounded wire somewhere. they have also pre ran them through the firewall through to the engine bay. you will find the, behind the fuse box on drivers side (you may have to remove fuse box lid). then those come through under the same side of the dash also and can tie into the pre ran wires for the upfitters. here is link to explain it. hope that helps.

 

Awesome Kevin thanks.
