Add two 6.8k ohm (6k8) resistors and remove one existing resistor as specified in the Bosch ME7.4.5 ECU Pinout Guide on Scribd . me7.4.5 pinout

microcontroller acting as the main processor unit.

| ECU Version | Key Differences | |-------------|------------------| | ME7.4 | Older, less memory, slower processor | | ME7.4.5 | Drive-by-Wire (ETC), wideband oxygen sensor (LSU 4.2) | | ME7.5 | Different pinout (T94 connector, not T121) | Connect to permanent power pins (typically shared on

Here are some essential signals and their corresponding pinout:

When working with boot mode for authorized software updates, never apply voltage to the boot pin directly without a resistor. This protection prevents current overdraw that can permanently damage the microprocessor. you can refer to specialized documentation:
