What circuits are shown on page 7 of the 1987-1989 F-Series/Bronco wiring diagram?

Power windows (master window control switch, front window motors, tailgate window motor and switches), power door locks, interior lights (dome, map/dome, cargo, glove box), fuel level senders and in-line fuel pump, inertia switch, body marker lights, taillights, license lights, backup lights, direction/hazard switch, trailer light relay, marker light relay, and trailer connectors.

What wire colors feed the tailgate power window motor?

The tailgate power window motor (with a circuit breaker) is fed by YEL-RED and RED-YEL wires, with TAN-BLK going to the tailgate window unit switch.

Which fuses are referenced on this diagram?

Fuse #14 (on an LT BLU-BLK wire for the window circuit) and Fuse #12 (on BLK-WHT wires for the tailgate window and door lock circuits).

How does the fuel level sender differ between Bronco and dual-tank trucks?

The Bronco uses a fuel level sender for gas single tank (ORG and BLK wires, YEL-WHT to the instrument cluster). Gas trucks with dual tanks use front and rear senders through a fuel tank select switch (RED, DK BU-YL, BRN-WHT, YL-LT BU wires); diesels use a fuel tank selector valve (DK BU-YL, YEL-LT BU).

What wire colors connect to the in-line fuel pump?

PNK-BLK feed wires and a BLK ground connect to the in-line fuel pump, routed through the electronic control assembly and inertia switch (NC).

This is page 7 of 7 of a Mitchell International (copyright 1994) wiring diagram covering 1987 through 1989 Ford F-Series trucks and Bronco. The page shows body-electrical circuits with full wire color codes: the master window control switch and right/left front power window motors (with circuit breakers), the tailgate window switches, tailgate power window motor and tailgate window unit switch, power door lock control switches and door lock motors, and interior lighting (dome, map/dome, cargo, and glove box lights, with separate connector pinouts for F150–F350 versus Bronco). It also diagrams the fuel system electrical circuits: the in-line fuel pump, electronic control assembly with inertia switch, fuel level senders for a gas single tank (Bronco), gas dual tanks with fuel tank select switch, and diesel dual tanks with fuel tank selector valve. Exterior lighting circuits include side/rear body marker lights, taillights, license lights, backup lights and switch, direction/hazard switch, trailer light relay, marker light relay, trailer brake connector, and trailer connector. Fuse #12 and Fuse #14 feeds are indicated, and fusible links (brown, black) are noted. Wire colors such as LT BLU-BLK, YEL-RED, PNK-LT GRN, BLK-PNK, and WHT-RED are labeled throughout, arranged on a grid (columns 24–27, rows A–E).

This document covers 1987-1989, which may differ from this 1985 Ford Bronco.
