Ford Mondeo Mk4 Rear Door Wiring Loom Harness Cable Left N/S BG9T-14240-GBB

Ford Mondeo Mk4 Rear Door Wiring Loom Harness Cable Left N/S is an original door wiring harness designed for installation on the driver's side in the rear part of the vehicle body. This component belongs to the Wires, harnesses and connectors group and serves as a crucial link between the vehicle's electrical system and the door equipment, ensuring stable power supply and signal communication. Thanks to its factory design, it is geometrically matched to the structure of the Mondeo Mk4 door, which facilitates service installation.

Purpose and placement in the vehicle

The presented harness is designed to operate in the rear left zone of the vehicle body, where it is responsible for connecting the door installation to the car's main electrical network. The placement on the vehicle has been factory-optimized for:

• routing wires through the grommet between the pillar and the door,
• proper arrangement of connectors in the rear left door,
• protection against abrasion during repeated opening and closing of the door. Such a fit reduces the risk of mechanical damage and facilitates the diagnosis of potential faults in the door electrical area.

Technical and functional characteristics

As an element from the Wires, harnesses and connectors group, this door harness is responsible for transmitting power and control signals to components located in the rear left door. Depending on the vehicle configuration, these may include door lock actuators, window controls, lighting, or sensors. The construction based on the original Ford design ensures:

• compliance with the factory electrical diagram of the Mondeo Mk4,
• appropriate length and distribution of wires relative to mounting points,
• dedicated connectors allowing for installation without modifying the wiring. Thanks to this, the harness is suitable both for standard replacement of a damaged cable and for repairs after collisions or interference with the door installation.

Benefits of using an original Ford harness

Using an original door harness in a Ford Mondeo Mk4 allows for maintaining the consistency of the electrical system with the manufacturer's specifications. The main advantages include:

• secure fit to the door structure – no need for shortening, soldering, or adapting wires,
• compatibility with factory connectors – the harness works with original plugs in the door and body,
• easier diagnostics – compliance with Ford service documentation makes it easier to locate potential breaks or short circuits,
• stability of electrical connections in the moving area of the door grommet. Such a solution is particularly beneficial in vehicles where the reliability of the central locking, window controls, or other functions dependent on the correct operation of the door installation is essential.

Component condition and service application

The offered harness is a used item, sourced from dismantling, which allows for economical repair while maintaining the original manufacturer's specification. This type of part is a good choice in situations where:

• wires in the door grommet have been damaged,
• there are intermittent power or signal losses in the rear left door,
• it is necessary to replace the complete harness after body and paint repairs. Replacing with an original door harness reduces the risk of problems resulting from unprofessional wire repairs, such as unstable connections or leaks in the grommet.
