VW / Audi 5-Pin Tail Light Wire Harness Connector – OEM 5K0972705 / 5G0972715 | Male & Female

The OEM 5K0972705 / 5G0972715 are 5-pin connectors used in Volkswagen and Audi tail light assembly harnesses. Cross-referencing both Golf MK6 (5K0972705) and Golf MK7/MK8 (5G0972715) OEM part numbers, this connector integrates stop light, turn signal, reverse light, tail/position light, and ground circuits in the rear light assembly. Available in Male and Female variants, bare or with 15cm pre-wired leads.

Key Specifications

Tail Light Connector Pin Functions

The 5-pin tail light connector on VW/Audi platforms typically serves: stop light (brake), turn signal, reverse light, tail/position light, and ground. A degraded connector causes intermittent brake light failures, turn signal faults, or reverse light malfunctions – all of which are safety-critical and may trigger B-code fault codes on VAG diagnostic systems.

Why Tail Light Connectors Fail

Tail light connectors are exposed to road spray, moisture, vibration, and thermal cycling from the light assembly. Terminal corrosion or housing damage causes intermittent brake light failures, turn signal faults, or reverse light malfunctions. Replacing the connector restores full tail light circuit integrity.

Variant Guide

• Male / Male 15CM – Plug-side connector for the tail light module
• Female / Female 15CM – Socket-side connector for the harness side

Installation Steps

1. Disconnect the vehicle battery
2. Remove the tail light assembly to access the harness connector
3. Release the locking tab and unplug the original 5-pin connector
4. Transfer terminals to the new housing or splice in the pre-wired variant
5. Reinstall the tail light and verify all functions (brake, turn, reverse, position)

Frequently Asked Questions
