Kazoo Tom, the wiring diagram shows the trailer running lights connected to BRN/WHT of the chassis cable and the tail lights and running lights are connected to BRN. According to the Ford users manual there are fuses on the steering column near the brake. Since I don't have a driver's door, it is next to impossible to get a look there, actually got stuck there once working on the slide switch. Will take out the driver's seat tomorrow and take a look. Cable cam loose on the tow dolly clearance lights and may have shorted causing a fuse to go.
