My brother in laws f350 has a factory bypass in the fuse box that allows upfitter switches 5 and 6 to remain powered with the truck off. Do the new gen3 s have that ability? I haven’t been able find it anywhere if it is.
Constant power to up fitter switches?

Sorry no one seems to have an answer for you. I would see if @FordTechOne will chime in - he would probably be the best source for this info. Good luck!
Per the Workshop Manual, only Super Duty is equipped with the secondary fuse position that allows the upfitter switches to have power at all times.
Until they take it away...
