I’ve found a complete lack of information about the Upfitter system. I work with a fleet of 8 SD’s from 2007 to 2022 and 2 Transit Vans, all with Power Strokes. Several of them came with wiring harnesses in the glove compartment, none have any info on what they are used for or even where they plug in. Can anyone point me in the direction of where to find this information? Thanks
Upfitter switch setup has changed a number of times over the years, and of course between truck models, so you will need to look for specific info for each different model you are working with.
Most have youtube videos made for them, so worth looking there for guidance.
Not sure what the wires you found in the glove box might be, not part of the upfitter switches. Also, check the owners manuals, they should have some reference to the upfitter switches aswell.
