Bosch 1928404196 141P EMS Series 89-Way Left-Exit Protective ECU Connector Backshell

Shield heavy-duty engine control unit pigtail bundles, enforce clean wire-harness routing, and deliver structural strain relief to high-density loom inputs with the genuine Bosch 1928404196 89-way connector cover. Precision-manufactured to Tier-1 original equipment automotive specifications by Bosch, this rugged protective backshell is the factory-specified capping component for the 141P Engine Management System (EMS) interconnect group. Engineered to snap seamlessly onto the main Bosch 1928404195 89-pin female ECU carrier plug block, it completely encloses the exposed rear wire-entry cavities, safeguarding delicate signal wires from mechanical abrasion, fluid drips, debris buildup, and directional strain.

The 1928404196 protective cap is molded from high-grade, glass-fiber reinforced polyamide (PA66 GF), granting it superior structural rigidness and defense against thermal aging across a severe operating window from -40°C up to +105°C. This specific variant features a sharp left-hand (LH) wire exit geometry, allowing harness builders to cleanly dress and tie down the massive 89-conductor cable trunk away from moving components or exhaust heat paths. Certified for extreme engine-bay environments, it maintains exceptional structural integrity under continuous mechanical vibrations tracking up to 8G (extensively deployed on commercial vehicles using Bosch EDC7 common rail ECU setups). This authentic component allows custom wiring loom fabricators, commercial fleet technicians, and tuning specialists to complete clean, professional, and reliable master engine harness assemblies right on the build bench.
