It is responsible for transmitting signals between the Parktronic system sensors, the reverse camera, and the vehicle's control modules, enabling the proper operation of the parking assistant and the rear view camera.

Thanks to dedicated wire routing and factory connectors, the harness allows for the preservation of the original electrical system architecture, minimizing the risk of interference, communication errors, and problems with safety system diagnostics.

Construction and Fit for Mercedes Citan W415

The harness is structurally adapted to the rear body area of the Mercedes Citan W415, facilitating its routing along the bumper and mounting elements. The connectors used are prepared to work with factory parking sensors and the reverse camera, ensuring a tidy installation without the need for modifications to the existing wiring.

The original Mercedes solution ensures:

• consistency with the vehicle's factory electrical diagram,
• easier diagnostics using service testers,
• proper shielding and routing of signal wires,
• compatibility with mounting brackets and grommets in the rear bumper.

Service Application and Benefits of Installation

Replacement of the rear bumper harness is recommended, among other things, after mechanical damage to the bumper, bodywork and paint interventions, or in case of problems with the operation of Parktronic and the reverse camera. Using an original harness allows for:

• restoring full functionality of parking assistance systems,
• avoiding makeshift wiring repairs,
• maintaining correct messages and indications on the onboard display,
• preserving compliance with factory safety standards.

For workshops specializing in the Mercedes brand, this is a component that facilitates professional repair of the vehicle's rear area, and for the end-user, it is a way to ensure trouble-free operation of assistance systems during maneuvering.

Condition, Verification, and Fitment

The offered harness is used, which in practice means it comes from a dismantled vehicle and has been verified for installation suitability. Before purchasing, it is advisable to compare the connector configuration and wiring layout with the solution used in your specific Citan W415 to ensure full compatibility with the vehicle's equipment (presence of Parktronic and reverse camera).

Additionally, thanks to dedicated technical markings, the harness can be easily identified in service documentation and parts catalogs, which simplifies the work for both mechanics and those assembling parts for repair.
