FORD:

ISSUE:
The "Lamp Out" warning lamp on the instrument panel may illuminate if the trailer wiring harness was installed incorrectly. This will occur if the wiring harness was installed on the wrong side of the lamp out warning module. The voltage reading to the module will drop, causing the module to illuminate the "Lamp Out" warning bulb on the instrument panel.
