What circuit does this 1979 Bronco wiring diagram cover?

It covers the tailgate power window circuit, including the window regulator safety relay, the instrument panel tailgate window switch, the key-actuated rear window regulator control switch, the tailgate window limit switch, and the tailgate power window motor.

What wire colors feed the tailgate window switches?

Power comes from splices S-211 via circuit 517 BK-W (black-white) and S-403 via circuit 297 BK-GR (black-green). The UP/DOWN circuits are 405 P-BL (purple-blue) and 404 P-GR (purple-green).

Which wire runs from the limit switch to the tailgate window motor?

Circuit 334 R-Y runs through connector C-1911 to the tailgate power window motor; circuit 333 Y-R feeds the tailgate window limit switch.

Where does the tailgate window circuit ground?

Ground is via circuit 57 BK, noted as 'Charge Start Run, to ground G-701'.

What connectors are used in the tailgate power window circuit?

Connectors shown include C-1902, C-1903, C-1904, C-1905, C-1907, C-1910, and C-1911, plus splices S-211, S-403, and S-1902.

This document is page 271 of a Haynes manual showing Fig. 10.149, the continuation (final section) of the 1979 Ford Bronco wiring diagram. It covers the tailgate power window circuit. Power feeds come from Power Distribution splices S-211 (circuit 517 BK-W) and S-403 (circuit 297 BK-GR). The diagram traces the circuit through the Window Regulator Safety Relay (connector C-1902), the tailgate/glass (T/G) Window Regulator Control Switch on the instrument panel (connectors C-1904, C-1903) with UP/DN circuits 405 P-BL and 404 P-GR, then through connectors C-1905 and C-1907 and splice S-1902 to the key-actuated Rear Window Regulator Control Switch. From there circuit 407 T-BK runs through connector C-1910 to the Tailgate Window Limit Switch (circuit 333 Y-R), then circuit 334 R-Y through C-1911 to the Tailgate Power Window Motor. Ground is via circuit 57 BK to ground G-701 (Charge Start Run). A reader can learn wire numbers, wire color codes, connector numbers, and component names for diagnosing the 1979 Bronco power tailgate window system.
