What years does this tailgate window motor circuit diagram cover?

The document states that the fuse, connector, and ground designations shown are for 92-95 models; for other years it directs readers to owner's and shop manuals.

What is the pinout of the C274 master tailgate window switch connector?

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

How do I test the master 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 isolated. With the rocker pushed UP, continuity should exist between terminals 4 and 2 and terminals 1 and 3, with terminal 6 isolated. With the rocker pushed DOWN, continuity should exist between terminals 3 and 6 and terminals 1 and 4, with terminal 2 isolated.

What wire colors control the tailgate window up and down functions?

Circuit 404 (Purple/Light Green, P/LG) is the tailgate window switch UP circuit and circuit 405 (P/LB) is the tailgate window switch DOWN circuit.

Where is the ground for this circuit located?

The diagram shows ground G201, labeled on the schematic as being at the left cowl panel (near the left kick panel area).

This document is a wiring reference for the power tailgate window motor circuit on a Ford Bronco, with the note that fuse, connector, and ground designations shown apply to 1992-95 models (others should consult owner's and shop manuals). A vehicle outline diagram locates key components and connectors: the battery, starter relay, ignition switch, I/P distribution box, I/P fuse panel, ground G201 at the left kick panel, connectors C274, C285, C418, and C429, the tailgate (TIG) window motor, the interlock switch on the latch, and the TIG key switch. The main section details the C274 gray master tailgate window switch connector, giving pin functions: pin 1 circuit 400 (LB/BK) power hot in ACCY or RUN; pins 2 and 5 circuit 57 (BK) ground; pin 3 circuit 404 (P/LG) window UP; pin 4 circuit 405 (P/LB) window DOWN. Step-by-step continuity test instructions using a self-powered test lamp or ohmmeter describe expected terminal continuity in neutral, UP, and DOWN switch positions. Additional inline connector pinout tables for C280F/C285M and C418 are shown, along with a full circuit schematic on the right side, though much of the fine print in these sections is difficult to read at this resolution.
