Before you chase a wire for three hours, clean the main chassis ground strap (from battery negative to the frame rail near the starter). On the F2000, 50% of "wiring diagram problems" are actually just corrosion at G1 (the central ground point).

Runs along the left frame rail (usually). It connects to the taillights, trailer socket, ABS sensors, fuel tank sender, and transmission sensors (ZF or MAN gearbox).
