Purpose and function in the vehicle

The presented socket with wiring is a component from the Wires, harnesses, and connectors group, responsible for the electrical power supply and control of the rear lamp on the left side of the vehicle. Its location in the rear zone, on the driver's side, means it works with the circuits for position lights, brake lights, turn signals, or reversing lights – depending on the lamp configuration used in a given unit. This component allows for:

• restoring full functionality of the rear lighting after damage to the factory connector,
• maintaining proper electrical communication between the vehicle's installation and the lamp,
• reducing the risk of light control system errors resulting from unstable connections.

Benefits of using an original Mercedes component

Using a component from the Mercedes brand ensures compatibility with the factory specifications of the GL X164 vehicle. The correct connector geometry, the right type of pins, and the matched wire length minimize the need for installation modifications and facilitate assembly in the original mounting points. Key advantages include:

• factory fit for the rear lamp on the left side of the body,
• stable electrical connection reducing voltage drops and light flickering,
• easier installation diagnostics thanks to maintaining the original wiring architecture.

Condition, origin, and service application

The item is offered as used, which makes it a reasonable choice for post-accident repairs, replacing a damaged connector, or restoring the efficiency of the installation in older GL X164 units. In practice, this allows for lower service costs while maintaining compliance with the factory manufacturing standard. The socket with wiring will prove particularly useful in situations where:

• mechanical damage to the connector occurred during lamp removal or replacement,
• the original harness was melted or corroded in the connector area,
• intermittent lighting failures occur due to loose contacts.

Compatibility and installation fit

Thanks to the preservation of the original connector design, the product integrates with the factory electrical installation without the need for adapters or plug modifications. The location at the rear on the left side clearly defines the mounting area, which facilitates the identification of the correct component during service work. Before purchasing, it is worth comparing the shape and type of the connector with the element currently installed in the vehicle to confirm full structural compatibility with the rear lamp used in the specific GL X164 unit.

Selection support and additional materials

For precise matching, you can use identifiers such as SKU, OEM part number, or available interchangeable numbers, which help verify compatibility with a specific vehicle configuration. These details are particularly useful when comparing parts with service catalogs or parts selection software. If you are planning a comprehensive repair or upgrade of the rear lighting zone in your Mercedes and need other elements from the same group, such as harness sections, additional connectors, or lamp adapters, check the available parts in the Mercedes wires, harnesses, and connectors category.
