Intended Use and Fitment for BMW E91 LCI

The presented plug with socket and wiring has been specifically designed for the left rear light in the BMW 3 Series E91 after facelift (LCI). This means that the connector's geometry, pin layout, and wire length are adapted to the factory installation, which facilitates assembly and reduces the risk of errors during connection.

By maintaining the original design, the component works well with the factory rear light, ensuring proper power supply for the parking light, brake light, turn signal, and other functions intended for the specific lighting variant.

Connector Construction and Technical Specifications

The plug is a complete socket with connector and wiring, ready for integration with the existing vehicle harness. The construction includes:

• a connector housing adapted for the left rear light,
• a set of wires extending from the connector,
• a factory pin configuration ensuring a stable electrical connection.

This solution allows for the replacement of a damaged connector without the need to interfere with the lamp itself. In practice, it is often sufficient to cut off the old, melted, or corroded connector and replace it with the presented plug, maintaining the correct wire order according to the car's installation.

Service Application and Benefits of Installation

The left rear light plug is particularly useful in situations where:

• the original connector has overheated or melted due to a poor connection,
• the connector has suffered mechanical damage during lamp removal,
• contact corrosion is causing circuit interruptions and lighting errors on the dashboard,
• the electrical system needs repair after a rear-end collision.

Replacing the connector with an original used part allows for the restoration of proper light function without resorting to makeshift solutions. This is an economical alternative to purchasing a whole new wiring harness, especially for older BMW models where a reasonable repair cost while maintaining the factory standard of execution is important.

Condition, Origin, and Fitment Quality

The component comes from a dismantled BMW vehicle, meaning it is a part that conforms to the manufacturer's factory specifications. This ensures correct dimensional tolerances, and the connector fits the lamp without modifications. The used nature of the product makes it an economical solution, while also maintaining the consistency of the electrical system with the original vehicle design.

Before installation, it is recommended to perform a standard check of the contacts and wire insulation, as well as to make correct connections to the vehicle's harness (e.g., by soldering and using heat shrink tubing) to ensure long-lasting and stable operation of the lighting system.
