Application and Vehicle Placement

The rear door wiring harness is specifically designed for installation in the rear part of the body, suitable for both the right and left sides. This precise fit for a specific body zone facilitates routing the wires through factory grommets and minimizes the risk of mechanical stress during door opening and closing.

The appropriate shaping of the harness supports the correct functioning of electrical components located in the rear doors, ensuring a stable connection with the vehicle's electrical system without the need for modifications to the factory setup.

Technical and Functional Characteristics

As a component from the Wires, Harnesses, and Connectors group, the harness is responsible for the safe routing of control signals and power between the rear doors and the rest of the electrical system. Using the original design limits voltage drops and interference, which is crucial for the operation of sensors, actuators, and other receivers located in the doors.

The harness is prepared to operate under typical door operating conditions, accounting for cyclic bending in grommets, temperature variations, and exposure to moisture from the body side. This makes it a stable service solution for repairs of the rear vehicle section's electrical system.

Brand, Origin, and Item Condition

The product comes from the Mercedes offering, meaning it adheres to factory manufacturing standards and is compatible with the electrical system design used in vehicles of this brand. Original origin facilitates integration with the existing body harness, without the need for modifications or connector adjustments.

The item is offered as used, allowing for an economical replacement of a damaged harness while maintaining compatibility with the factory electrical system design. This is a practical service solution for situations involving broken wires, damaged insulation, or continuity issues within the rear door circuits.

Service Application and Installation Benefits

Using this harness in the rear part of the vehicle allows for restoring correct door electrical system functionality without interfering with the main body installation. Installing an original harness reduces the risk of installation errors typical of universal solutions and also simplifies future diagnostics.

This solution is particularly beneficial for repairs after mechanical damage to wires in door grommets, where it is necessary to recreate the factory wiring path and maintain compatibility with other elements of the vehicle's electrical system.
