The AMP Multilock connector from TE Connectivity is a sealed automotive connector system widely used by European and Asian OEMs including BMW, Volkswagen, Toyota, and Honda. The Multilock name refers to the dual-locking mechanism — a primary terminal lance lock and a secondary TPA (Terminal Position Assurance) tab that prevents contact back-out. Available in a range of configurations from 2 to 12 pins, Multilock connectors accept 22–16 AWG wire and are sealed to IP67 with individual wire seals. The system is designed for underhood and exterior applications including lighting, sensors, and switched circuits. Multilock connectors are one of the most common sealed connectors in global automotive production, making them essential knowledge for anyone working on European or Japanese vehicle harnesses.
