Purpose and function in the vehicle

The presented wiring harness is a component of the Rear lights and brake lights system in BMW 4 Series F32, F33, and F36 LCI facelift models. It is responsible for:

• transmitting control signals to the tail lamp located in the trunk lid,
• ensuring proper power supply for individual lighting functions,
• maintaining electrical compatibility with the factory BMW control module.

Thanks to its factory-fit design for the rear body section, the installation process is orderly, maintaining the original cable routing points.

Construction and fitment for BMW

The wiring harness was developed by BMW with the specific LCI lamp layout in mind, which translates into correct cable lengths, appropriate connectors, and compatibility with factory mounts in the trunk lid. This means:

• no need for cutting or soldering wires when the correct part is selected,
• a secure connection with the tail lamp and the vehicle's electrical system,
• preservation of the car's original electrical architecture.

Such a solution is particularly important for post-collision repairs or when replacing a damaged harness, where compliance with the manufacturer's service documentation is essential.

Benefits of using an original wiring harness

Using an original trunk lid wiring harness in a BMW 4 Series offers a number of practical benefits:

• Seamless integration with the existing electrical system without the need for additional adapters,
• reduced risk of errors in the vehicle's diagnostic system,
• proper operation of tail lights, including brake and turn signal functions,
• maintenance of the factory safety and vehicle visibility standards.

This used OEM component is a sensible choice for repairs where technical correctness and compliance with the vehicle's design are priorities, while simultaneously optimizing service costs.

Condition and service application

The offered wiring harness is a secondary market component intended for service applications in the rear of the vehicle. It is particularly suitable for situations such as:

• wire damage resulting from wear or mechanical interference,
• post-collision repair of the rear body section,
• restoring full lighting functionality after improper installation modifications.

By maintaining the factory geometry of wires and connectors, the harness allows for orderly installation and easier diagnostics of any potential future faults.
