Bosch 1928405075 EMS 154P-V 60P Signal Secondary Locking TPA

The Component: Genuine Bosch OEM multi-position terminal position assurance (TPA) component / Premium Bosch EMS Series Secondary Locking Clip / Custom engineered exclusively for the high-density signal and data circuit quadrant of engine management connectors / Dual-rail side-insertion locking profile / Formed from high-grade, premium glass-filled Polyamide (PA66-GF30) / Component Part Number: 1928405075 / Alternate Reference: 1 928 405 075.

Applications & Fitment: Optimized as a vital verification and retention safeguard within complex automotive engine management system (EMS) wiring looms. This authentic Bosch pink/magenta secondary lock is the factory-specified counterpart for the 60-position (60P) signal/data block of the 154P-V EMS female contact housing. Acting alongside its companion power clip, this TPA slide inserts directly through the side of the 60-way contact housing once sensor and communication lines are populated. If a single micro-terminal contact is unseated or skewed, the TPA's parallel rails catch on the terminal shoulder and halt installation, instantly flagging the error to prevent assembly-line faults or intermittent field connections. Once fully snapped home, it reinforces terminal seat reliability against extreme engine bay vibrations, longitudinal wire pull, and thermal fatigue. The high-performance glass-reinforced compound ensures excellent dimensional stability and snap-lock resilience across an operational window of -40 to 125 °C. Crucial replacement stock for motorsport wiring professionals, ECU repair technicians, and specialist automotive component distributors.
