Vehicle Application and Function

The offered harness is designed for the rear of the vehicle, where it is responsible for transmitting signals from the parking sensors to the vehicle's control unit. A correctly selected cable in this area is crucial for:

• stable communication between the PDC sensors and the car's electronics,
• precise detection of obstacles behind the vehicle,
• proper functioning of the parking system's acoustic and visual signals,
• minimizing interference and errors in the parking assistant's operation.

Thanks to its factory-matched design, the harness maintains the correct length, connector placement, and wire routing within the rear zone of the vehicle.

Construction, Connectors, and Compatibility

The rear parking sensor harness is constructed as a complete solution with appropriately spaced connectors for the PDC sensors and a main lead for the vehicle's electrical system. The connectors used are prepared to work with factory parking sensors, allowing for installation without any electrical system modifications.

The original cable design reduces the risk of leaks, chafing, and electrical contact issues that often arise with unprofessional repairs. This solution is particularly beneficial when replacing a damaged harness after a collision, connector corrosion, or interference with the rear bumper.

Benefits of Using an Original Harness

Using the factory harness in the PDC system offers a range of practical advantages:

• Full Integration with the Electrical System – the cable is ready to work with the original parking system without the need for soldering or creating adapters.
• Proper Wire Routing – the harness is shaped to fit the rear body's geometry, facilitating correct placement in the bumper and minimizing stress.
• Stable Sensor Operation – proper shielding and wire gauge selection help reduce signal interference.
• Trouble-Free Diagnostics – maintaining the original installation architecture simplifies work with service testers and fault localization.

Item Condition and Service Application

The offered harness is a used part, removed from a vehicle, and intended for reinstallation in a vehicle requiring the restoration of the rear parking system's functionality. It is a practical solution for situations where the existing cable has suffered mechanical damage, connector corrosion, or has been disturbed during bodywork or painting operations.

Choosing an original harness from the same model series ensures installation consistency, avoids compatibility issues, and reduces the time needed for PDC system installation and configuration.
