2024 F250 Upfitter Switch Wiring Colors

2024 F250 Upfitter Switch Wiring Colors. The ford upfitter switches are optional instrument panel mount switches (option code 66s) that control passenger side mounted relays. I found a bundle of wires in the passenger.

My 2016 f350 has the upfitter switches, i was able to pull the wires up enough from under the hood and behind the fuse box. We have been working with some customers who had a hard time figuring out what color wires were which switch on their 24’s.
