Ford Truck Turn Signal & Headlamp Wiring Diagram - Connector Pinouts C-701 to C-807
Electrical wiring diagram showing headlamp switch, turn-signal switch, lamps, connectors, and color-coded wires.
This document is one page of a factory-style automotive wiring diagram covering the exterior lighting and turn signal circuits — headlamp switch, headlamp dimmer switch, turn and emergency signal switch (with and without speed control), right-hand low-beam headlamp, right-hand front side marker lamp, right-hand front park and turn signal lamp, and left/right turn indicator lamps in the instrument cluster printed circuit. The upper half is a schematic showing circuit numbers and wire colors (e.g., 285 BR, 810 R-BK, 3 GR-W, 2 W-BL, 282 GR, 283 Y-BK, 385 W-R, 44 BL, 57 BK ground) routed through connectors C-208/C-208A, C-305, C-701, C-713, C-801, C-807, C-901 and splice S-807. The lower half is a connector legend showing pinouts and physical locations: C-208A at the rear of the instrument cluster (printed circuit with gages), C-713 under the instrument panel near the steering column (part of steering column assembly), C-801 on the R.H. or L.H. fender apron, C-802/C-804 on the brake pedal support at the stop lamp switch, C-803 on the toe board at the headlamp dimmer switch, C-805 behind the I/P for the emergency warning flasher, C-806 on the "Y" brace for the turn signal flasher, and C-807 behind the headlamp. Part base numbers 14401, 13076, and 9A840 identify the harness assemblies.

Frequently asked questions
- Where is the turn signal (T/S) flasher located according to this diagram?
- Connector C-806 shows the T/S flasher is on the "Y" brace, behind the instrument panel; it connects circuits 44 BL and 8 O-Y, and the connector is blue.
- Where is the headlamp dimmer switch connector and what wires go to it?
- Connector C-803 (harness 14401) is on the toe board, extreme left-hand side, at the headlamp dimmer switch, with wires (2) 13 R-BK, 15 R-Y, and (2) 12 GR-BK.
- What wire colors come out of the turn and emergency signal switch?
- The turn and emergency signal switch outputs circuits 3 GR-W, 283 Y-BK, 282 GR, 2 W-BL, 385 W-R, and 44 BL, passing through connector C-305 or C-713 (C-713 is used with speed control).
- Where is the emergency warning flasher connector located?
- Connector C-805 (14401) is behind the instrument panel on the left-hand side at the emergency warning flasher, carrying wires 284 R, 383 R-W H, and 385 W-R H.
- What connector is behind the headlamp and what wires does it carry?
- C-807 (harness 13076) is located behind the headlamp and carries 12 LG-BK, 13 R-BK, and 57 BK; it serves the R.H. low beam headlamp with ground through 57 BK.
