In this article we take a look at the third generation Ford F-Series Super Duty, produced from 2013 to 2016. Here you will find the Ford F-250 / F-350 / F-450 / F-550 2013, 2014 and 2015 wiring diagram, information on the location of the fuse boxes in the vehicle and the assignment of each fuse (fuse layout) and relay.
The Ford F-250 / F-350 / F-450 / F-550 cigar lighter (socket) fuses are fuses 82, 83, 87, 88, 92 and 93 in the engine compartment fuse box.
Fuse box location
Passenger compartment
The fuse panel is located in the passenger’s footwell behind the cover.
Engine compartment
The power distribution box is located in the engine compartment.
UPFITTER CONTROLS (IF EQUIPPED)
The upfitter option package provides four switches, mounted in the center of the instrument panel. These switches will only operate while the ignition is in the on position, whether the engine is running or not. However, it is recommended that the engine remain running to maintain battery charge when using the upfitter switches for extended duration or higher current draws. (This is even more important for vehicles with diesel engines since the glow plugs are also draining battery power when the ignition key is in the on position.)
When switched on, they provide 8 amps, 12 amps or 20 amps of electrical battery power for a variety of personal or commercial uses.
Relay box
There will also be a relay box located on the driver’s side end of the instrument panel. See your authorized dealer for service.
There will also be one power lead for each switch found as a blunt-cut and sealed wire located below the instrument panel and to the left of the steering column.
