Aftermarket 813 971 987 /  813971987

The Component: Replacement VAG 813971987 (813 971 987) 3-way unsealed female socket connector housing block. Round-profile multi-pin utility series classification / High-grade impact-resistant Polyamide / Neutral White-Cream / 3-Position circular inline arrangement / Component Alias Code: 813971987.

Applications & Fitment: Engineered as a secure, specialty low-voltage wire-to-wire or wire-to-device inline mating connection block. This 3-pin round connector body is a long-standing utility fixture across classic and modern Volkswagen Audi Group platforms—including VW, Audi, Seat, Skoda, and Porsche builds—serving as the definitive factory interface for specialized interior and mechanical sub-assemblies. Most commonly encountered as the electrical interface plug for rear window wiper motor units (e.g., Audi 100/200/5000 C3 series setups), interior blower regulator feeds, specialized vacuum pumps, dashboard cluster links, and auxiliary comfort modules. Sized precisely to offer absolute pin separation and drop-in factory restoration, it eliminates loose tracking connections or signal dropouts. Highly vulnerable to tab fracture, rear collar cracking, or losing its internal retention grip if field service technicians roughly pry at the housing shell using inappropriate tools during component diagnostic teardowns, or if terminal pins are forced out incorrectly.
