Ford Bronco Camper/Trailer Circuit - Fuse Links F, G, P & Troubleshooting (Pg 109)

Shop-manual camper/trailer wiring page: circuit fed through Fuse Links F, G and P at the starter relay; troubleshooting hints for trailer lamps that won't light.

AI caption · Photo 109 of 120

This is page 109 of a Ford electrical/vacuum troubleshooting manual (EVTM-style), covering the Camper/Trailer circuit. The 'How The Circuit Works' section explains that power for the camper or trailer circuits is supplied through fuse links at the starter relay: trailer exterior lamps and accessories are powered through Fuse Link G, while trailer brakes and brake lamps are powered through Fuse Link F. It refers the reader to section 32-01 of the shop manual for further details. The Component Location table places Fuse Links F and G at the starter relay and Fuse Link P near the trailer lamps relay on the left-hand fender apron, and directs readers to the Location Index at the back of the manual for connector, ground, and splice descriptions. A Troubleshooting Hints table addresses the condition 'Trailer Lamps don't light,' listing possible causes (no voltage at the R or Y wires of the circuit; poor in-line circuit connections) and actions (check Fuse Links F and G and wiring; clean/tighten and/or repair open in wiring). Faint diagram content from adjacent pages is visible but not readable. The page carries no explicit year or model identification.
