Ford F-100-F-350 & Bronco Cruise Control Wiring Diagram - Speed Control 37-01-5

This is a scanned page (37-01-5) from a Ford shop manual section covering the Speed Control (cruise control) System. The page presents FIG. 6, the speed control wiring diagram for F-100 through F-350 trucks and the Bronco (the top of the page shows the tail of FIG. 5, the E-100-E-350 diagram). The schematic traces cruise control circuits from the servo assembly through a grommet in the dash panel to the amplifier assembly via connectors C-714 and C-717, and shows the amplifier central grounding point. Other components shown include the speed sensor, horn relay, horn, horn switch, turn signal switch with the OFF/ON/SET/COAST speed control switch (with 680 ohm and 120 ohm resistors), ignition switch, a 20 amp fuse in the fuse panel, brake switches (plunger and mechanical types), fusible link, connectors X and Y, and part of the 14401 wiring assembly. A wire color legend table lists circuit numbers (1, 460, 57, 614, 810, 151, 297, 828, 827, 735, 826, 825, 734, 46DA) with their primary colors, secondary colors, and stripe indication. Reference code L2154-2D appears at lower right. Readers can identify cruise control wire colors, circuit routing, and component connections for troubleshooting.
