This connector uses a mixed-pitch design: 1mm pitch contacts for signal circuits and 3.5mm pitch contacts for power circuits, allowing both high-density signal routing and adequate current capacity for power circuits in a single 81-pin connector. Used in VW, Audi, Skoda, and SEAT engine control units across multiple vehicle generations.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Numbers:\u003c\/strong\u003e 1355171-1 (housing), 368389-1, 368382-1 (associated components)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e TE Connectivity (formerly Tyco\/AMP)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Count:\u003c\/strong\u003e 81 pins\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Pitches:\u003c\/strong\u003e 1mm (signal contacts) + 3.5mm (power contacts)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Type:\u003c\/strong\u003e Female socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIP Rating:\u003c\/strong\u003e IP67\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e VW Group ECU main connector (VW, Audi, Skoda, SEAT)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eVW ECU Connector — Mixed-Pitch Design\u003c\/h3\u003e\n\u003cp\u003eThe 81-pin VW ECU connector uses two contact sizes in the same housing:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1mm pitch contacts (signal rows):\u003c\/strong\u003e For sensor inputs, actuator outputs, and CAN bus communication circuits.
