Purpose and function in the vehicle

The described component is a wiring harness with a socket designed for the right rear combination lamp in the Mercedes B-Class W245 generation. It is responsible for supplying power and control signals to the parking light, brake light, turn signal, or reversing light bulbs, according to the specific lamp configuration. It is mounted in the rear part of the body on the passenger side, in the immediate vicinity of the lamp, which facilitates service and diagnostics.

Thanks to the factory fitment to the Mercedes electrical system, the correct wire geometry, proper harness routing, and compatibility with original connectors are maintained, which reduces the risk of contact looseness and improper lighting operation.

Construction and technical features

The right rear lamp socket is integrated with a section of wiring, forming a complete assembly ready for installation in the vehicle. The construction includes:

• a factory connector matched to the rear lamp on the right side,
• a properly selected wiring harness with cross-sections adapted to current loads,
• a connector on the vehicle's electrical system side, enabling direct plugging into the original electrical circuit.

This solution minimizes the need for interference with the main body harness, reduces soldering and the use of universal connectors, and thus improves the reliability of the entire rear lighting system.

Benefits of using an original component

Using an original socket with wiring for the rear lamp in the Mercedes W245 provides a number of practical service benefits:

• Plug & play relative to the factory installation – no need for harness modifications, matching universal plugs, or changing the connection diagram.
• Proper cooperation with the light control system – correct resistance and load values for body modules reduce the risk of dashboard errors.
• Consistency with the original electrical diagram – facilitates diagnostics, measurements, and any further repairs in the rear lamp area.
• Reduction of problems with flickering, dimming, or complete loss of light on the right rear side of the vehicle.

This solution is especially recommended for damage resulting from contact corrosion, overheating of bulb holders, trunk flooding, or mechanical damage to the lamp and its wiring.

Condition, application, and installation

The item comes from dismantling, 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 of the right rear lamp without the need to purchase an entire new body harness or use replacement solutions with uncertain parameters.

Installation involves replacing the existing socket with a fragment of the wiring in the rear part of the vehicle. Thanks to the factory connectors, the operation is straightforward for an automotive electrician: after disconnecting the battery, the old lamp harness is removed, the connectors and mounts are swapped, and the new assembly is installed, ensuring proper wire routing and protection against moisture and abrasion.
