1968 Mercury Cougar Turn Signal, Hazard & Brake Light Wiring Diagram (Fig. 42)

This is page 19-58 from a factory service manual schematics section (Group 19 — Schematics), showing FIG. 42 — Turn Signals, Emergency Warning and Brake Lights — Cougar (drawing reference K 2257 A1). The schematic diagrams the complete turn signal, emergency (hazard) warning flasher, and brake light circuits for the Cougar. Key components shown include the right- and left-hand turn signal lamps with 14290 wiring assemblies grounded on the alternator (26 circuit), 14401 wiring assemblies, the turn signal switch (7200 assembly), left and right turn signal indicator lamps (10B942 assembly), the brake lamp switch fed through a 15 amp fuse from the ignition switch accessory terminal (circuit 8A/8), the emergency warning flasher switch, and the turn signal indicator relay. A wiring color code legend cross-references circuit numbers (2, 3, 5, 8, 9, 10, 44, 57C, 385, 436-447, 458, 459, etc.) to wire colors such as white-blue stripe, green-white stripe, orange-black stripe, blue, black, violet, green, and brown. Readers can trace individual circuit numbers (e.g., 44, 49, 50, 385, 440, 441, 448, 449, 458, 475, 511, 514) through connectors and switches to diagnose turn signal, hazard flasher, and brake light problems.
