It is responsible for transmitting signals between the mirror's electronics and the door and body installation, enabling the correct operation of all electrical and control functions intended by the manufacturer.

This component belongs to the Exterior Mirrors category, meaning it has been designed with specific requirements for resistance to vibrations, temperature changes, and humidity in the door and pillar area.

Construction, Color, and Fitment

The wiring harness has been prepared for installation in a mirror painted in Black Sapphire Metallic - 475, which facilitates the identification of the correct version when selecting parts for a specific vehicle. The connectors and wire routing used are compliant with BMW's factory standard, allowing for installation without any modifications to the existing wiring.

Key functional features:

• original connector geometry matched to the driver's mirror and door,
• wires routed according to the factory harness path,
• maintained compatibility with LCI version electronics.

Component Condition and Service Application

The offered wiring harness is from the group of used BMW parts, allowing for economical repairs while maintaining the original manufacturer's specifications. This solution is particularly useful for:

• repairs after mirror damage resulting from a collision or scrape,
• problems with intermittent mirror operation caused by damaged wires,
• the need to restore factory wiring after incorrect modifications.

Using an original wiring harness helps reduce the risk of communication errors in the body installation and eliminates the need to adapt universal solutions.

Benefits of Using an Original Mirror Wiring Harness

Choosing this component offers a range of practical advantages for everyday vehicle operation:

• reliable electrical connections – connectors designed for the specific model minimize the risk of loose connections and interference,
• consistency with factory installation – no need for cutting, soldering, or adapting wires,
• easier diagnostics – maintaining the original wiring layout simplifies the work for service centers using BMW documentation.

As a result, this wiring harness is suitable for both professional workshops and discerning owners who independently maintain their car's electrical system.
