Ford Taurus / Mercury Sable Sedan Exterior Lighting Wiring Diagram (2 of 2)
Chassis electrical wiring diagram showing backup, stop, license and rear marker lamp circuits with color codes.
This page (12-34) from Chapter 12, 'Chassis electrical system,' of a repair manual shows a wiring diagram titled 'Typical exterior lighting system - sedan models without Lamp Out Warning (2 of 2)' for Ford Taurus and Mercury Sable sedans. Power comes from two circuits: Fuse 6 (15A, hot in run) feeding an ORG wire through the Transmission Range (TR) sensor (P-R-N-D-D/2-1, AX4N only) to the left and right backup lamps via BLK/PNK wires, with branches to the instrument cluster and Remote Anti-Theft Personality (RAP) module; and Fuse 28 (15A, hot at all times) in the I/P fuse panel feeding the Brake On/Off (BOO) switch via LT GRN/RED, then RED/LT GRN to the left and right hi-mount stop lamps and rear stop lamps. The diagram distinguishes Sable and Taurus wiring branches and shows circuits for the left/right rear turn lamps, rear side marker lamps, rear park/stop lamps, and left/right license lamps, with wire colors including BRN, RED/LT GRN, ORG/LT BLU, and LT GRN/ORG, and BLK ground returns. Two connector branches are marked '(NOT USED).' A reader can trace fuse feeds, wire colors, and lamp grounds for diagnosing rear lighting problems.

- Fuse 6, a 15A fuse that is hot in run, feeds an ORG wire through the Transmission Range (TR) sensor to the left and right backup lamps via BLK/PNK wires.
- Which fuse and switch feed the brake/stop lamps?
- Fuse 28 (15A, hot at all times) in the I/P fuse panel feeds the Brake On/Off (BOO) switch via a LT GRN/RED wire; the switch output is RED/LT GRN to the hi-mount and rear park/stop lamps.
- What wire color goes to the hi-mount stop lamps?
- Both the left and right hi-mount stop lamps are fed by RED/LT GRN wires, with BLK ground wires.
- Does this diagram cover vehicles with Lamp Out Warning?
- No. It is labeled 'Typical exterior lighting system - sedan models without Lamp Out Warning (2 of 2).'
- What wire colors feed the rear turn lamps?
- The left rear turn lamp circuit uses LT GRN/ORG and the right rear turn lamp uses ORG/LT BLU, with BRN feeds for the park/marker filaments and BLK grounds.
