What fuse powers the backup lamps on a 1995 Ford Bronco?

A 15A fuse in position E of the Engine Compartment Fuse Box, hot in RUN (see page 13-4), feeding circuit 298 (P/O).

What wire color is the backup lamp feed circuit on a 1995 Bronco?

Circuit 140, black/pink (BK/PK), carries 12V in reverse from the backup lamp switch (manual transmission) or Transmission Range sensor (automatic) toward splice S116 on page 93-2.

How do the backup lamps work with an automatic transmission (E4OD or 4R70W)?

With the transmission in REVERSE, the Transmission Range (TR) Sensor directs current from circuit 298 P/O (12V in run) out on circuit 140 BK/PK to illuminate the backup lamps. TR sensor switch testing is on page 149-9.

How do the backup lamps work with a manual transmission?

With the transmission in REVERSE, the backup lamp switch (closed in reverse, connector C166) provides voltage from circuit 298 P/O out on circuit 140 BK/PK to illuminate the backup lamps.

Where is diagnostic information for the 1995 Bronco backup lamp circuit?

The diagram refers to section 17-01 of the Service Manual for diagnostic information.

AI caption December 2011 · Photo 998 of 1799

This document is page 93-1 of the 1995 Ford Bronco electrical/wiring diagram manual, covering the Backup Lamps circuit. It shows that power comes from a 15A fuse (position E) in the Engine Compartment Fuse Box, hot in RUN, on circuit 298 (P/O — purple/orange). For manual transmissions, voltage passes through connector C166 to the Backup Lamp Switch (closed in reverse, component location 151-6 B10), then out on circuit 140 (BK/PK) through connector C103F. For 4R70W or E4OD automatic transmissions, the Transmission Range (TR) Sensor (location 151-6 F2, switch testing on page 149-9) handles the reverse signal: inputs include circuit 32 R/LB (12V start, Starting System page 20-2), 463 R/W (All-Wheel Drive page 34-1), 298 P/O (12V run), and 359 GY/R via connector C1012; outputs include 32 R/LB (12V in P or N), 57 BK, 140 BK/PK (12V in reverse), and 199 LB/Y to the E4OD (page 30-1) or 4R70W (page 29-4) transmission pages. Circuit 140 continues through connectors C103F/C103M (151-2 F6) to splice S116 on page 93-2. Notes explain that in REVERSE, the backup lamp switch or TR sensor directs current to illuminate the backup lamps. Diagnostic information is referenced in Service Manual section 17-01.
