ECU Versions: Engine Control Unit Software

Hello fellow DIY enthusiasts,

Can anyone provide me with information about the hardware components used in engine control units (ECUs) within a specific model series?
Specifically, this would be:
EDC 15 VM+2.V1
e.g., VW 074 906 018 AJ or Bosch 0281010461.
compatible with VW 065 906 018 or Bosch 0281010710.

Specifically, I would like to know if the multi-connector for the engine control unit has different versions or configurations.
Are the multi-connectors the same within a series, for example, are the two MSG connectors mentioned above (EDC 15 VM+2.V1) identical?

Hi,

To the best of my knowledge, the connectors are all the same for that specific engine control unit model.

Best regards, Rainer.
