Vehicle Application and Placement

The presented socket with a wiring harness section is dedicated to the rear right side of the Mercedes W207 body, where it is responsible for powering and controlling the rear combination lamp. Its placement in the trunk and wheel arch area requires a component resistant to typical operational stresses such as vibrations, temperature changes, or occasional moisture.

Thanks to its factory design, the harness maintains the correct wire routing geometry, which facilitates installation and minimizes the risk of mechanical stress on the connectors. This is particularly important for the rear light and brake light, where connection stability directly translates to driving safety.

Socket Construction and Function

The socket is structurally matched to the right rear lamp, ensuring proper contact positioning and a secure click-in fit within the lamp housing. The connector used allows for quick disconnection and reconnection during servicing, without the risk of damaging the pins when handled correctly.

The wiring harness section integrated with the socket allows for direct plug-in to the vehicle's factory installation. This plug-in solution reduces the need for soldering or creating adapters, which in turn decreases the system's susceptibility to voltage drops and lighting malfunctions.

Benefits of Using an Original Mercedes Part

Using an original socket with a wiring harness for the rear lamp in a Mercedes W207 offers a range of practical benefits:

• factory fit for the right rear lamp on the body,
• stable electrical connection for parking, brake, and turn signal functions,
• reduced risk of installation errors due to maintained original wire geometry,
• easier diagnosis of lighting faults thanks to a predictable harness layout,
• no need for universal connectors or installation modifications.

This solution is particularly beneficial for collision repairs, replacing a damaged lamp, or troubleshooting intermittent right rear lighting issues.

Condition and Service Application

This part comes from the group of used Mercedes parts, allowing for economical repair while maintaining original technical specifications. In practice, this means the ability to restore full functionality to the rear lighting without the need to invest in a complete new body harness.

The socket with wiring harness is suitable for both professional workshops specializing in the Mercedes brand and independent garages that expect parts compliant with factory standards. It is also a good option for DIY car owners looking for a technically matched OEM replacement.
