1996 Ford Bronco Brake Shift Interlock Wiring Diagram - BOO Switch & Actuator

This document is a Ford wiring diagram (diagram number D12572-C) for the brake shift interlock circuit, uploaded as applying to a 1996 Ford Bronco. It shows two power feeds from the instrument panel (I/P) fuse panel: Fuse 10 (10A, hot in RUN) supplying circuit 296 (White/Purple) directly to the Brake Shift Lock Actuator, and Fuse 13 (15A, hot at all times) supplying circuit 383 (Red/White) then circuit 10 (Light Green/Red) to the Brake On/Off (BOO) Switch. From the BOO switch, circuit 511 (Light Green) branches to both the Brake Shift Lock Actuator and a 390-ohm Brake Shift Lock Resistor. The actuator is drawn with an internal solid-state module, diodes, a resistor, and a solenoid coil. Both the actuator and resistor ground through circuit 57 (Black) wires that join at a splice before reaching chassis ground. A callout notes to see EVTM Cell 37 for more details of this circuit. A reader can learn the fuse locations and ratings, wire circuit numbers and color codes, component names, resistor value, and ground path for diagnosing brake shift interlock problems (e.g., a shifter that will not come out of Park).
