What fuse powers the master tailgate window switch?

Fuse panel position 14, a 20A circuit breaker that is hot in ACC or RUN, feeds the master tailgate window switch via a LB/BK wire.

What fuse powers the key-operated tailgate window switch?

Fuse panel position 12, a 20A circuit breaker that is hot at all times, feeds it via a BK/W wire.

What does the tailgate latch switch do in this circuit?

The tailgate latch switch, connected by a T/BK wire from the tailgate window switch and an R/Y wire to the motor, is open when the tailgate is not fully closed, interrupting the circuit to the power window motor.

What wire colors connect the master switch to the tailgate window switch?

P/LG and PK/LB wires run from the master tailgate window switch through connector 517 to the key-operated tailgate window switch.

Where does the master tailgate window switch ground?

It grounds through a BK wire to ground point G701.

This is a wiring diagram for a Ford Bronco tailgate power window circuit, credited to community member FireGuy50. It shows two power feeds from the fuse panel: fuse position 14, a 20A circuit breaker that is hot in ACC or RUN, feeding the master tailgate window switch through a LB/BK (light blue/black) wire; and fuse position 12, a 20A circuit breaker hot at all times, feeding the key-operated tailgate window switch through a BK/W (black/white) wire. The master tailgate window switch (up/down) grounds through a BK wire at ground point G701 and connects to the tailgate window switch via P/LG (purple/light green) and PK/LB (pink/light blue) wires through connector 517. The key-operated tailgate window switch outputs a Y/R (yellow/red) wire directly to the tailgate power window motor and a T/BK (tan/black) wire to the tailgate latch switch, which is highlighted in red and annotated as being open when the tailgate is not fully closed. From the latch switch, an R/Y (red/yellow) wire completes the circuit to the tailgate power window motor. The diagram is useful for diagnosing tailgate window failures, especially issues caused by the tailgate latch safety switch interrupting the down circuit.
