VAG 3C0973737 14-Way Sealed Female Headlight Connector 

The Component: Genuine VAG OEM 14-position high-density sealed female flat contact receptacle / Premium Volkswagen Audi Group automotive multi-pin inline plug assembly / Advanced hybrid terminal matrix layout (8 x 1.5mm channels + 6 x 2.8mm power channels) / Integrated side-loaded violet/pink secondary terminal position assurance (TPA) locking slide / Top-mounted structural snap-fit mechanical retention latch / Molded from premium-grade, rugged, weather-stabilized Polyamide (PA66) / Component Part Number: 3C0973737 / Alternate Engineering Reference: 3C0972737 / 3C0 973 737.

Applications & Fitment: High-performance, waterproof, and vibration-proof 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 female housing block is the factory-specified main interface most notably used for high-intensity discharge (HID), xenon, and matrix LED headlamp assemblies, adaptive front-lighting systems (AFS), front-end parking radar networks, and complex bumper-mounted sensor looms. Engineered for absolute protection against harsh elements, its heavy-duty outer shell houses a high-visibility yellow silicone perimeter seal that completely insulates the mating plane from water, dust, engine fluids, and road salt. The side-mounted violet secondary lock ensures strict terminal position assurance (TPA); once the mixed-size crimp 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.
