Bosch 1928405073 94-Way EMS Connector Signal Secondary Locking Bar

The Component: Genuine Bosch 154P-V EMS (Engine Management System) Series 94-way signal secondary locking bar mechanism. Engineered as a slide-in high-visibility terminal assurance slider / High-grade impact-stabilized PBT engineering polymer frame / Component Part Number: 1928405073 / Global Order Reference: 1928405073-19R.

Applications & Fitment: Designed as a mandatory secondary locking hardware component for the high-density 94-position Bosch Engine Management System (EMS) ECU plug matrix. This authentic pink-coded secondary locking bar is engineered to slide laterally into the face of the female connector housing after wire termination. Its specialized profile physically intercepts and double-locks the independent 0.6mm micro signal terminals (such as the Bosch BCB series), establishing a mechanical safeguard that prevents terminals from backing out or shifting under severe powertrain harmonics. It is an essential component required during custom wire loom construction, professional motorsport harness configuration, and exact factory ECU plug reconstruction. Molded from rugged, temperature-stabilized Polybutylene Terephthalate (PBT), this locking wedge ensures reliable locking retention and remains resilient up to its maximum 120°C engine bay threshold. It acts as an identical factory-original replacement hardware part commonly specified for commercial fleet servicing, performance ECU updates, and precision workshop wiring assembly repairs.
