VW 3-Pin 1.5mm Taillight / Seat Wire Harness Connector – OEM 7N0972703 / 5K0972713
Direct OEM-specification replacement for the Tyco / TE Connectivity 3-pin wire harness connector used on taillight assemblies and seat harnesses across Volkswagen platforms. Cross-references VW OEM part numbers 7N0972703, 5K0972713, 7N0 972 703, and 5K0 972 713. Uses the 1.5mm contact series in black nylon housing — a widely used interior and exterior body harness connector on VW Group MQB and PQ platform vehicles.
The 3-pin 1.5mm connector is used on two common failure circuits on VW vehicles. As a taillight connector, it is located in the boot (trunk) area or rear bumper harness, exposed to moisture ingress from the boot seal. A failed connector causes a non-functioning taillight, brake light, or indicator — a roadworthiness violation. As a seat harness connector, it is located under the seat cushion and is exposed to spilled liquids and mechanical stress from seat adjustment, causing seat heating, ventilation, or adjustment faults.

Q: My VW Golf taillight is not working after a boot liner removal — could it be the connector?
A: Yes. The 3-pin taillight connector is the most common failure point during boot liner removal on VW Golf and Polo. The 1.5mm terminal is easily bent when the connector is pulled without pressing the release tab. Inspect the connector before replacing the taillight bulb or LED module.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
