Purpose and function in the vehicle

The offered component is dedicated to installation in the rear right section of the vehicle, in the area of the side lamp. It is responsible for supplying power and control signals to the lighting assembly, enabling the correct operation of position lights, turn signals, and other functions provided in the specific vehicle configuration. Thanks to its precise fit for the Mercedes system, the wiring harness and panel work seamlessly with factory connectors, which reduces the risk of loose contacts, contact overheating, and lighting control system errors.

Construction, connectors and compatibility

This element belongs to the Wires, harnesses and connectors group, meaning it has been designed as an integral part of the body's electrical installation. The construction includes:

• factory connectors matched to the rear lamp on the right side,
• properly routed wires ensuring correct distribution of electrical loads,
• mounting point placement consistent with the CLA C117 body architecture. Such a solution promotes connection stability, minimizes the risk of mechanical damage to the wires, and facilitates service in case of future lighting maintenance.

Condition, service application and benefits of installation

The product is offered as a used component, which allows for an economical repair of the lighting system while maintaining the manufacturer's original specifications. In practice, this means the ability to restore full functionality to the rear right lamp without the need for interfering with the factory installation, soldering wires, or using adapters. Replacing a damaged harness or wiring panel with an original component of this type is particularly beneficial when the vehicle experiences:

• intermittent operation of the rear right lamp,
• lighting error messages on the instrument cluster,
• signs of overheating or corrosion on the lamp connector contacts. Using an original component helps maintain system integrity, which is important for both reliability and future diagnostic procedures at a service center.

Professional installation and technical aspects

Due to the nature of the component and its role in the lighting system, installation by a person with experience in working with vehicle electrical systems is recommended. Proper routing of the harness, protection against abrasion, and correct fastening of connectors contribute to the long-term, stable operation of the rear lamp. A properly selected and installed wiring panel in the rear right part of the body reduces the risk of errors in lighting control systems and decreases the probability of failures resulting from unstable connections or unprofessional repairs.
