I have a 2014 F250 and need to install an upfitter switch and wiring harness. I need to find a wiring diagram. I have searched this site and Ford Fleet site, but no luck so far.

Thanks

 

Is this what you are looking for?

Larry,

Thanks, that helps a lot. I am also looking for the wiring diagram for the truck in general. The wiring harness appears to have multiple empty connectors. I am assuming that the wiring harness is use for multiple options, i.e., fog light wiring is in the harness even if no fog lights were installed. I plan to use the upfitter switches to power LED lights up front and additional back up lights in the rear.

you would need a book of wiring diagrams and connectors number to even locate what you are looking for...there are 4 feed thru wires in the main wiring harness going through the firewall....they are blunt cut wires on each side of the firewall you an use to hook to the upfitter wires tapes to this main harness if the upfitter were install at the factory.
