: Connect the ECU K-Line pin to Pin 7 of your universal OBD2 breakout box or flash tool interface.

The ME20 ECU uses multiple power and ground pins to ensure stable operation and to separate noisy loads from sensitive electronics: Elias checked the K-Line

: K-Line or CAN High/Low pins (e.g., 11D and 12D for CAN) facilitate diagnostic communication.

There are two main hardware variants:

For basic communication, immo-off procedures, or "virginizing" the ECU using tools like or SVCI , you must provide constant power ( +12Vpositive 12 cap V ), ignition power ( ACCcap A cap C cap C ), and Ground ( GNDcap G cap N cap D Pin Function Pin Number Main Power (+12V) Ignition Power (+12V) Ground (GND) Pins 4, 5, 6 Diagnostic/K-Line Pin 8 or 28 (typically for OBD/K-Line) Detailed Component Connections
