Maybe of interest, I see many posts where folks ask what fuses are hot for various purposes. I compiled this from the Ford Service Manual for 2021-2022 F150, the wiring diagrams showing Power Distribution.
One PDF for the Body Control Module (fuse box in the cabin)
One PDF for the Battery Junction Box (fuse box in the engine compartment)
3 Categories of function are listed

- Hot in Start or Run
- Hot at All Times
- Relay Control
- ALWAYS VERIFY FUSE FUNCTION BEFORE USING
- The lists may not be complete and not all trucks may have all fuses listed
- Not all fuses listed are 'blade-type' that lend to fuse taps
- If you install a tap be sure to test to find the 'Hot Leg' and orient your tap properly!
