I'll cite the relevant sources. I'll also include a disclaimer about the risks of working with ECUs.
The Bosch ME20 engine control unit (ECU) is a foundational electronic management system used across various European vehicles from the late 1990s and early 2000s. Whether you are performing an engine swap, diagnostics, or bench flashing, having a verified pinout diagram is critical to avoid destroying sensitive electronic components.
Verification was performed using:
The connector pins are usually divided into two or three major groups, often with labels like A, B, or C on the plug plastic itself. Always map these physically rather than relying solely on diagrams.
