Bosch 1928405452 91way 196P EMS / Contact Housing 91P / Code 1

The Component: Genuine Bosch high-performance heavy-duty ECU receptacle housing. 196P EMS (Engine Management System) Series taxonomy / 91-position multi-row high-density female casing / Code 1 Standard Keying Profile (Jet Black / Premium Glass-Reinforced PA66 / Sealed Waterproof / Hybrid 91-Pin Configuration / Vehicle-Side Module Interface / Component Variant Alias: 1-928-405-452 / Global Order Reference: 1928405452).

Applications & Fitment: Engineered as a premium, original equipment (OE) heavy-duty engine control unit (ECU) connection plug designed explicitly for complex powertrain management networks. This 91-pin female receptacle block is a core commercial vehicle and industrial loom staple—prominently integrated across major heavy transport platforms (including MAN, Case IH, and Fiat industrial networks under global OEM reference 47529132) where it typically mounts alongside its 105-way engine-side counterpart to populate a unified 196-pin management interface. It features an integrated mechanical slide-locking lever mechanism that pulls the connector securely onto the ECU pin header, ensuring a zero-tolerance, gas-tight mating fit that entirely eliminates contact fretting under harsh structural vibration and extreme chassis harmonics. Engineered to meet strict tier-1 heavy-vehicle validation parameters, its hybrid cavity configuration uses high-grade mat seals and specialized sealing plates to form an absolute 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.
