Thanks to the below quote from 2013, was able to verify under hood fuses 27 gets power when key-On, and #4 gets power when transmission in Reverse.
Fuse #32 in rear fuse box (under seat) has blown and a new fuse blows within 5 seconds.
The b u lamps are 7watt LED and test good.
Trailer wiring and backup wiring look normal.
Could use guidance on how to troubleshoot for a short / crossed wiring.

Front fuse #27 gets power from the ignition switch RUN/START circuit. Then it goes through the Reverse switch on the tranny, and then through front fuse #4, and then to the light green wire (A) on the trailer connector. Does that work? That proves the reverse switch on the tranny operates.
Rear fuse #32 gets constant power from the battery in all ignition switch modes, so if there's no 12V on either side of that fuse, then either the fuse socket is erratic (twist the fuse blades slightly to improve the contact) or else your front 125A megafuse is dead, and I'm certain the plethora of other failures would make you mention those along with the backup lights being dead.
See how you can trace a bad section of wiring if only you know the voltages?
