1996 Ford Bronco Backup Lamps Wiring Diagram (93-1) - Reverse Light Circuit

This is page 93-1, "Backup Lamps," of a Ford wiring diagram set, uploaded as part of a 1996 Ford Bronco documentation album. It shows the backup (reverse) lamp circuit power flow. Power originates from a HOT IN RUN 15A fuse (position E) in the Engine Compartment Fuse Box (referenced to pages 13-4 and 13-10, See Power Distribution) on circuit 298 P/O (pink/orange). Two configurations are shown: for manual transmissions, circuit 298 P/O feeds the Backup Lamp Switch through connector C166; the switch closes in reverse and outputs circuit 140 BK/PK (black/pink). For C6 automatic transmissions, power feeds the Park/Neutral Position Switch through connector C127 (with switch testing referenced to page 149-11); the switch also ties into the starting system via circuit 33 W/PK (12V start) and circuit 32 R/LB (12V in Park or Neutral), referencing Starting System pages 20-2 and 20-4. In reverse, the switch outputs circuit 140 BK/PK through C127. Both branches converge and pass through connector C103 as circuit 140 BK/PK, continuing to splice S116 on page 93-3. Callout notes explain that with the transmission in reverse, the respective switch provides voltage to illuminate the backup lamps.
