VAG 3C0973837 14-Way Sealed Male Headlight Connector

The Component: Genuine VAG OEM 14-position high-density sealed male tab housing / Premium Volkswagen Audi Group automotive multi-pin inline coupling plug / Advanced hybrid terminal matrix layout (12 x 1.5mm tab channels + 2 x 2.8mm power tab channels) / Integrated side-loaded violet/pink secondary terminal position assurance (TPA) locking slide / External heavy-duty mechanical locking retention ramps / Molded from premium-grade, rugged, weather-stabilized Polyamide (PA66) / Component Part Number: 3C0973837 / Alternate Engineering Reference: 3C0972837 / 3C0 973 837.

Applications & Fitment: High-performance, waterproof, and vibration-proof inline interconnect system designed for exterior vehicle electronics and harsh engine bay environments across Volkswagen, Audi, SEAT, and Škoda automotive platforms. This authentic 14-pin VAG male housing block is the factory-specified inline coupling interface used for high-intensity discharge (HID), xenon, and matrix LED headlamp assemblies, adaptive front-lighting systems (AFS), chassis-to-bumper wiring transitions, and front-end parking radar networks. Engineered to mate flawlessly with the female plug (3C0973737), its heavy-duty outer shell provides the necessary mechanical shroud to isolate and protect the electrical mating plane from water, dust, engine fluids, and road salt when fully engaged. The side-mounted violet secondary lock ensures strict terminal position assurance (TPA); once the mixed-size crimp male blade contacts are seated into place, closing this slide mechanically bars the terminals from backing out under severe chassis resonance or accidental pull. An essential service item for automotive electrical engineers, professional lighting retrofitters, and high-volume wholesale trade suppliers.
