Pinout | Me7.4.5

Note: "ME7.4.5" refers to a Bosch Motronic engine control unit family used on various Volkswagen Group gasoline engines (commonly found in VW/Audi 1.8T, 2.0, etc.). Pinouts can vary by vehicle model, connector type, and hardware revision. Below is a concise, commonly encountered ME7.4.5 pin mapping for the 60‑pin (or 55/60) rectangular main harness connector used on many 1.8T installations. Treat this as a general reference; confirm against your vehicle’s service manual or measured signals before wiring or diagnosing.

When using specialized tuning cables (like those for Trasdata), ensure the power LED is active. If using a metal positioning frame, the ECU might be powered through the frame rather than the main connector pins. me7.4.5 pinout
