1928405074 154P-V EMS / Secondary Locking 94P / Power side

The Component: Genuine Bosch OEM multi-position terminal position assurance (TPA) component / Premium Bosch EMS Series Secondary Locking Clip / Specifically engineered for the power-circuit quadrant of high-density engine management connectors / Precision comb-profile insertion architecture / Formed from high-grade, structurally rigid glass-filled Polyamide (PA66-GF30) / Component Part Number: 1928405074 / Alternate Reference: 1 928 405 074.

Applications & Fitment: Designed as a critical safety and orientation component within complex automotive engine management system (EMS) wire harnesses. This authentic Bosch lilac secondary lock is factory-specified for the power side block of the 94-position (94P) 154P-V EMS female contact housing, along with 91-position variants in the 196P EMS family. In high-density engine control unit (ECU) installations, this component acts as a physical safety gate. Once terminals are inserted into the primary housing cavity, this TPA slide pushes into place across the rows; if any terminal socket is not fully seated or misaligned, the comb teeth encounter physical interference and refuse to seat, instantly alerting the harness assembler to a fault. When fully locked, it mechanically prevents terminal back-out under extreme diesel/gasoline engine vibrations and severe thermal cycling. The glass-reinforced nylon compound ensures maximum rigidity and crisp snap-lock performance within an operational temperature envelope of -40 to 125 °C. Vital service stock for motorsport wiring professionals, ECU repair facilities, and specialized automotive component wholesalers.
