Purpose and function in the vehicle

The presented wiring harness with a plug is a component of the Rear lights and brake lights system, responsible for transmitting electrical signals to the rear right lamp. Its placement in the rear right part of the vehicle allows for direct connection to the lamp and integration with the factory estate body wiring.

This type of solution is particularly useful when:

• the original wiring harness was damaged during disassembly or bodywork repairs,
• there are intermittent lighting failures on the right side due to broken wires or worn connectors,
• it is necessary to replace the lamp along with matching the correct plug.

Construction and fitment for Audi A4 B8 Estate

The harness has been designed specifically for the geometry of the Audi A4 B8 estate body, which facilitates routing the wires through the original mounting points. The factory plug ensures proper pin alignment and compatibility with the rear right lamp, without the need for modifying the installation.

Such fitment translates into:

• stable electrical connection with lighting control modules,
• reduced risk of errors in the lighting control system,
• easier installation compared to universal replacements.

Component condition and service application

The product is offered as a used part, which allows for an economical repair of the lighting system while maintaining the manufacturer's original specifications. This type of harness is suitable both for replacing a damaged section of the installation and for completing the rear right lamp in the case of post-accident repairs.

Thanks to the preservation of the factory design, it is possible to minimize the time required for diagnostics and installation, as well as avoid additional soldering or wire adaptation.

Benefits of using an original wiring harness

• Full compatibility with the vehicle's installation – correct connectors, wire length, and pin layout.
• Reduction of problems with lighting error messages on the instrument cluster.
• Ability to restore the proper operation of position lights, brake lights, turn signals, or license plate lighting (depending on the lamp configuration).
• Secure connection, without makeshift connectors or installation modifications.
