Question about 1991 Ford F150
Do you know of a source for step-by-step wiring instructions (preferably with diagrams/photos) for installing a 7-pin wiring harness on this vehicle?
i've completed the installation on the trailer in accordance with the US color coding, but am a bit overwhelmed with how to hook up the pickup-side of the equasion to electric brakes, back-up lights, and charging the RV battery with the pickup alternator.
I believe you can look up the manufacturer of the trailer plug kit and find the wiring diagram there. On alot of the trailer plug kits, they have pics and diagrams in the package. The 7 pin plug (truck side) is available with the pig tail set up that plugs directly into the wiring harness for the lights. Then all you would have to worry about is the 2 wires for the electric brakes.
