Which fuse powers the rear window defrost control on a 96 Bronco?

Fuse 7, a 15A Hot in Run fuse, feeds circuit 8 (O/Y wire) to the Rear Window Defrost Control through connector C278 (pin 3), and also feeds the Turn Flasher on the fuse panel.

What wire color feeds the heater control assembly?

Circuit 399, a BR/W (brown/white) wire from Fuse 1 (30A), feeds the A/C-Heater Control Assembly (with A/C) or the Heater Control Assembly (without A/C) through connector C296.

What wire and connector supply power to the air bag diagnostic monitor?

A 296 W/P (white/purple) wire from Fuse 18 (10A) goes through connector C217, pin 1, to the Air Bag Diagnostic Monitor (see page 46-1).

Are these circuits hot at all times?

No — all three fuses shown (Fuse 1 30A, Fuse 7 15A, Fuse 18 10A) are labeled 'HOT IN RUN', so they are only powered with the ignition in Run.

This document is page 13-10 of the Power Distribution section of the 1996 Ford Bronco electrical/wiring diagram set. It shows three "Hot in Run" circuits fed from the fuse panel (detailed on page 13-5): Fuse 1 (30A), Fuse 7 (15A), and Fuse 18 (10A). Fuse 1 feeds circuit 399 (BR/W wire) to the A/C-Heater Control Assembly (with A/C, page 54-2) or Heater Control Assembly (without A/C, page 53-2) through connector C296. Fuse 7 feeds circuit 8 (O/Y wire) to the Rear Window Defrost Control via C278 (page 56-1) and the Turn Flasher on the fuse panel (page 90-1). Fuse 18 feeds circuit 296 (W/P wire) through splice S242 to multiple loads: the Air Bag Diagnostic Monitor via C217 (page 46-1), the Programmable Speedometer/Odometer Module (PSOM) in the instrument cluster via C252 (pages 64-1, 60-7), the Electronic Shift Control Module via C209 and C222 connectors when equipped with shift-on-the-fly (page 34-1), the Shift Lock Actuator via C236 (page 37-1), and onward to splice S902 (page 13-11) through connectors C200, C299, and C206 (the latter with overhead console only). Wire colors, connector numbers, pin numbers, and cross-reference page numbers are given for tracing each circuit.
