REAR TAILGATE HARNESS 23-26 FORD F250, 350

The rear tailgate harness is the electrical wiring assembly that connects the vehicle’s main electrical system to the components installed in or around the tailgate.

Main function

It carries power, ground, and electrical signals between the truck body and tailgate components, such as:

• Rearview/tailgate camera
• Tailgate release/latch switch
• Tailgate ajar position signal
• Power-operated tailgate functions, when equipped
• Tailgate lighting and other electrical accessories, depending on configuration
• Communication signals for certain tailgate/parking-assist components

The harness allows these components to communicate with the vehicle's control modules and operate correctly. Ford documentation concerning 2023–2024 Super Duty models specifically identifies the tailgate wire harness as part of the rear camera system; a harness fault can contribute to intermittent, blue, or black rear-camera images.
