Purpose and function in the vehicle

The presented tailgate lamp wiring harness has been designed specifically for use in the Audi A4 B9, with placement on the rear left side. It is responsible for reliable power supply and control of the tailgate light, which is important for both safety and compliance with vehicle lighting regulations. Using a dedicated wiring harness reduces the risk of installation errors, accidental short circuits, or unstable contact at the connectors.

Construction, connectors, and compatibility

The component combines the tailgate light lamp and a matched wiring harness with a factory plug, allowing for a plug-in installation without the need for modifying the wiring. The wire construction is adapted to the geometry of the Audi A4 B9 tailgate, ensuring that the harness routing is organized and the wires are not exposed to excessive bending or abrasion during opening and closing of the tailgate. The used connector ensures secure locking in the socket and stable electrical parameters under typical operating conditions.

Condition, service application, and part selection

The product is used, which in practice means it comes from disassembly and can be an economical solution for post-accident repairs or replacing damaged tailgate lighting. Choosing an original wiring harness with the lamp allows for maintaining the integrity of the electrical system and avoiding problems typical of replacements with uncertain specifications. Part selection should be based on the OEM number and interchangeable numbers, which facilitates verifying compatibility with a specific Audi A4 B9 equipment version.

Benefits of using an original wiring harness with the lamp

• Factory fitment to the tailgate geometry and mounting points on the left side.
• Stable electrical connection thanks to a dedicated plug and properly selected wires.
• Reduced risk of installation errors compared to universal solutions.
