Bosch Me20 Pinout Verified High Quality

The Bosch ME2.0 ECU is a cornerstone of late 90s and early 2000s automotive engineering, famously powering high-performance Mercedes-Benz engines like the M112 V6 and M113 V8. Whether you are performing a diagnostic repair, an IMMO OFF procedure, or bench-flashing for performance, having a verified pinout is critical to avoid damaging these sensitive control modules.

1. Official Bosch Technical Documentation: The gold standard, though often proprietary.
2. OEM Wiring Diagrams: Cross-referencing the specific vehicle model’s wiring loom against the ECU connector.
3. Physical Testing: Technicians using multimeters to trace continuity between the ECU pin and the sensor plug.

For basic communication and power-up on a bench, the following pin assignments are typically verified across standard ME 2.0 documentation: Ground (GND/Terminal 31): Connect to main chassis ground pins. Power (+12V Constant/Terminal 30): Connect to battery positive. Ignition (+12V Switched/Terminal 15):
