Me7.4.5 Pinout Jun 2026
Before making physical wire connections, it helps to understand what is under the metal cover of this control module. The Bosch ME7.4.5 relies on a complex multi-chip memory structure:
The pinout for the ECU, commonly found in Peugeot and Citroën vehicles, varies slightly depending on the specific plug configuration (Plug A, B, or C). For bench flashing or diagnostics, the following connections are typically used: General Bench Pinout Power (+12V): Plug B, Pin G4; Plug C, Pin H2 Ignition (+12V): Plug B, Pin F4 Ground (GND): Plug B, Pin H4; Plug C, Pin L4 K-Line: Plug B, Pin B1 CAN High: Plug B, Pin J3 CAN Low: Plug B, Pin J4 Boot Mode & Flashing
The pinout for the ME7.4.5 is organized across several connectors. While the specific layout can vary slightly depending on the manufacturer (Stellantis vs. VAG), the following table provides a comprehensive overview of the most common and critical pin assignments, compiled from detailed technical resources.

Comprehensive Guide to the Bosch ME7.4.5 ECU Pinout and Bench Programming
A pinout is a detailed diagram or list that shows the layout and function of each pin or connector on a specific electronic component, such as an ECU. In the case of the ME7.4.5 ECU, the pinout is essential for understanding how to connect and interface with the unit, as well as for troubleshooting and repairing issues.
