i am putting work lights and LED warning lights on the back rack of the 2014 F350 diesel in work.
where are the wires for the upfitter switches, and are they prewired into the fuse box, or do i have to hook them up?

 

The Upfitter wires are located on the driver's side under the dash close to the firewall. They are prewired to the switches and fused.

see page 4 of this bulletin to help you locate them

thanks. i kinda figured they would be in that area, just was not sure if they were prewired or if i had to hook them up like the 04 i did a few months ago.

 

This helped me!

 

I have a coin holder in place of the switches. its to the right of the brake controller. are there any existing wires under the dash that are pre wired so all i would need is the switches?

 

As I read the Ford bulletin and see pictures of the 3 parts needed to install the switches, so, the simple answer is no.

You have one connector to plug the upfitter harness into the truck wiring (assumes this connector is the power from the underhood Power Distribution Box) and then you snake a wiring harness over to where you mount the relays. See above eBay link and associated part numbers.

If no switches, you need all 3 parts.

Bummer. I have found some kits on Ebay. Theyre selling for 146.00 shipped I probably should talk to my wifes son at Ford and see if he can better that price.
