Purpose and Function in the Lighting System

The presented socket with wiring is intended for installation in the rear right section of the W204 estate body and works with the tail light integrated into the tailgate or fender, depending on the body version. This component is responsible for a stable electrical connection between the vehicle's wiring harness and the tail light, minimizing the risk of circuit interruptions, flickering bulbs, or errors in the light control system.

The plug socket solution with a factory wiring harness allows for maintaining the correct pin order and appropriate wire gauges, which is crucial for the proper functioning of all tail light functions within the Rear Lights and Brake Lights category.

Connector and Harness Construction

The socket is designed as a dedicated Mercedes electrical system component, featuring a precisely shaped plastic housing and a set of contacts matched to the right rear tail light. The integrated wiring harness provides:

• appropriate wire length for safe routing within the luggage compartment,
• factory-finished ends for correct connection to the vehicle's electrical system,
• maintenance of correct polarity and sequence of light signals.

Thanks to its original design, the connector integrates well with factory harness clips and guides, facilitating installation and reducing mechanical stress on the wires during operation.

Benefits of Using an Original Rear Tail Light Socket

Using a dedicated socket with wiring in the Mercedes W204 estate, on the right rear side of the vehicle, allows for restoring full lighting functionality without the need for electrical system modifications. The key benefits include:

• Compatibility with Factory Tail Light – the precisely shaped plug and pin arrangement eliminate issues with ill-fitting aftermarket replacements.
• Reduced Diagnostic Errors – correct resistances and wire gauges contribute to the proper operation of control systems.
• Secure Electrical Connection – stable contacts minimize the risk of overheating, sparking, and localized voltage drops.
• Easier Diagnostics – maintaining the original installation architecture simplifies work for electricians and service centers specializing in Mercedes.

Condition, Installation, and Service Application

This component is a used part, offered as a used electrical system component, providing a cost-effective service solution for repairs after collisions, mechanical damage to the tail light, or overheating of the factory socket. Replacing the entire connector with a section of the wiring harness is often a more durable solution than temporary soldering of individual wires.

Before installation, a standard inspection of the contacts, wire insulation, and proper routing of the harness within the vehicle is recommended to avoid chafing and excessive bending. Thanks to the preservation of the original connector geometry, installation is orderly and predictable, reducing work time and the risk of errors.

Part Selection by Numbers and Additional Materials

When selecting a rear tail light socket for a specific body version and year, it is advisable to use the OEM part number and interchangeable numbers, as well as data from the manufacturer's catalog. If you have doubts about compatibility with a specific equipment version, comparing the installed connector with the one currently in your vehicle may be helpful.
