Bosch 1928405063 94-Way Female EMS ECU Connector Housing (Code C)

Uses 84 x BCB 0.6 terminals + 6 x BDK Terminals and seals + 4 x MQS 1.5 CB Terminals (not included)

The Component: Genuine Bosch 154P-V EMS (Engine Management System) Series 94-way female mixed-contact engine control unit (ECU) connector housing. Features a high-density 94-position layout divided into key signal and power zones / Code C polarization profile / Black glass-reinforced PA66 GF30 structural composite shell / Secondary locking interface compatible / Wire-to-Device configuration / Component Part Number: 1928405063 / Order Reference: 1928405063-5R9.

Applications & Fitment: Engineered specifically for main engine management systems, powertrain control modules (PCMs), and complex transmission control setups demanding high pin-count signal density paired with localized high-current power routing. This authentic Bosch 94-pin female plug serves as a primary wiring loom interface for high-performance automotive engine management systems (EMS). The high-density contact array relies on a precision hybrid contact matrix consisting of three distinct terminal sizes to optimize current distribution while minimizing overall package size. The layout features 84 cavities optimized for low-current BCB 0.6mm signal lines, 4 cavities for medium-capacity MQS 1.5mm CB terminals, and 6 large-gauge cavities designed for heavy-duty BDK 2.8mm power/ground terminals. Molded from premium PA66 GF30 (30% glass-fibre reinforced Polyamide 66), the housing maintains maximum dimensional stability, flame resistance, and structural strength under structural engine bay vibration and operating temperatures ranging from -40°C to +105°C. This housing features clean-body and locking-lance cavity structures to ensure definitive terminal alignment. It is universally applied across motorsport wiring projects, high-end commercial fleet harness building, and exact OEM repair applications for engine wiring looms.
