What years does this Ford Bronco tailgate window motor circuit diagram cover?

The document states its fuse, connector, and ground designations are for 92-95 models; others should see owner's and shop manuals.

What are the pin functions of the C274 master tailgate window switch connector?

Pin 1 is circuit 400 (LB/BK) power, hot in ACCY or RUN; pin 2 is 57 (BK) ground; pin 3 is 404 (P/LG) tailgate window switch UP; pin 4 is 405 (P/LB) tailgate window switch DOWN; pin 5 is 57 (BK) ground.

How do I test the power tailgate window switch?

Use a self-powered test lamp or an ohmmeter. In neutral, there should be continuity between terminals 4 and 2 and terminals 3 and 6, with terminal 1 disconnected. With the rocker pushed UP (close window), continuity should exist between terminals 4 and 2 and terminals 1 and 3, with terminal 6 disconnected. With the rocker pushed DOWN (open window), continuity should exist between terminals 3 and 6 and terminal 1's pair, with terminal 2 disconnected. Note the connector view is the reverse of the switch pinout.

Where is the ground for the tailgate window circuit located?

The diagram shows ground G201 located at the left kick panel (L. Kick), and the schematic references a ground at the left cowl panel.

Which wire colors control tailgate window up and down?

Circuit 404 (Purple/Light Green) is the tailgate window switch UP circuit and circuit 405 (Purple/Light Blue) is the DOWN circuit; power is circuit 400 (Light Blue/Black) and ground is circuit 57 (Black).

This document is a Ford Bronco tailgate (rear) window motor circuit reference, stating that its fuse, connector, and ground designations apply to 1992-95 models (others should consult owner's and shop manuals). It includes a vehicle overview drawing locating key components: the battery, starter relay, power distribution box, I/P TIG fuse in the instrument panel fuse panel, ignition switch, ground G201 at the left kick panel, connectors C274, C285, C429, and C418, the interlock switch, TIG key switch, and the tailgate window motor. A detailed pinout is given for the C274 gray master tailgate window switch connector: pin 1 = 400 (LB/BK) power hot in ACCY or RUN, pin 2 = 57 (BK) ground, pin 3 = 404 (P/LG) window UP, pin 4 = 405 (P/LB) window DOWN, plus a 57 (BK) ground. Step-by-step continuity test instructions using a self-powered test lamp or ohmmeter explain which terminals should show continuity in neutral, UP, and DOWN rocker positions, noting the connector view is the reverse of the switch pinout. Bottom sections show inline connector pinouts (C286F/C285M and C418) with circuit numbers and wire colors, and a full wiring schematic of the tailgate window circuit.
