Ford F-Series Super Duty Trucks - Wiring Factory Auxiliary Upfitter Switches


If you are looking to use the factory upfitter switches in a Ford F-Series Super Duty Truck (F-150, F250, F350, F450, F550) then this tip may be helpful to you.

The 4 factory switches are typically located on the lower passenger side of the dash, below the stereo.
 They can be used to power and control additional accessories, when the vehicles ignition switch is in the on position.

The auxiliary upfitter switch wires aren't typically the wires you will clearly see right bellow the driver side steering column. 
You can typically find the wires and the relays under the plastic cover, located on the end of the driver side dash.

Once that cover is removed, you should see the black relay pack.

You can remove the black cover to reveal the 4 auxiliary switch relays. The output wires will be located below the relay pack, coming out of factory black split loom.

 Near the output wires, you should see a white tag that identifies the aux output wire colors with the aux switch number. 

AUX 1 - Yellow
AUX 2 - Green/Brown
AUX 3 - Violet/Green
AUX 4 - Brown 

You should be able to located the fuses for the auxiliary switches in the fuse panel to identify the max current for each switch. I believe AUX 1-2 are 30 Amps, and AUX 3-4 are 10 Amps.

If you need more room to work, you can unclip the relay pack and pull it out under the driver steering column right near the parking brake.
