Original Bosch 1928405455 105 way header

The Component: Genuine Bosch high-performance heavy-duty ECU harness plug housing. 196P EMS (Engine Management System) Series taxonomy / 105-position multi-row high-density female contact casing / Code 1 Standard Keying Profile (Jet Black / Premium Glass-Reinforced PA66 / Sealed Waterproof / Hybrid 105-Pin Configuration / Engine-Side Harness Interface Plug / Component Variant Alias: 1-928-405-455 / Global Order Reference: 1928405455).

Applications & Fitment: Engineered as a premium, original equipment (OE) heavy-duty engine control unit (ECU) harness plug designed explicitly for complex powertrain management wiring networks. This 105-pin female contact housing is a foundational commercial vehicle and industrial loom staple—prominently integrated across major heavy transport platforms where it typically mounts directly alongside its 91-way vehicle-side counterpart (1928405452) to form a unified 196-pin module interface. It features an integrated mechanical slide-locking lever mechanism that pulls the connector securely onto the main ECU pin header, establishing a low-tolerance, gas-tight mating fit that entirely eliminates contact path fretting under harsh structural vibration and severe engine compartment harmonics. Engineered to meet strict tier-1 heavy-vehicle validation parameters, its hybrid 5-row cavity configuration uses high-grade radial mat seals and specialized internal sealing plates to form an absolute environmental barrier against high-pressure washdowns, road spray, salt crusting, and hot engine fluids. Highly vulnerable to slide rail binding or locking lever fracture if field service technicians attempt forced lever rotation without verifying that the primary internal slide carriage is clean and completely un-obstructed.
