The Component: Genuine Bosch OEM multi-position harness backshell protective assembly / Premium Bosch EMS Series Lever-Actuated Wire Cover / Custom engineered specifically for the 60-position signal and data circuit quadrant of engine management plugs / Preassembled design featuring integrated lever pivot gears and a fixed 180-degree flat left-side wire outlet collar / Formed from high-stability, impact-resistant glass-filled Polyamide (PA66-GF30) / Component Part Number: 1928405072 / Alternate Reference: 1 928 405 072.

Applications & Fitment: Engineered to provide structural protection, strain relief, and effortless mechanical mating across high-density automotive engine management system (EMS) wiring looms. This authentic Bosch black 60-way cover is the factory-specified backshell for the 60-position (60P) signal block within the 154P-V EMS female ECU interface connector assembly. Placed directly over the populated contact block, this cover serves a dual purpose: it routes the dense sensor and data wire bundle cleanly out to the left side of the engine control unit (ECU), and it houses the precise gear-tooth tracks that engage the connector's mating lever. When the lever is closed, these integrated gears multiply mechanical force to pull the high-pole connector down onto the ECU header evenly, preventing pin misalignment and reducing insertion effort. The 30% glass-reinforced nylon construction delivers superior resistance against impacts, under-hood vibrations, and continuous exposure to engine oils, fuels, and thermal cycling across a -40 to 125 °C operating envelope. Essential replacement or build inventory for professional motorsport harness builders, ECU repair labs, and trade auto-electrical stockists.
