Example B — M7 on 1.8T engines (Audi/VW) — condensed common pins:

: The Bosch M7.9.7 is a standard module for many European Lada models, featuring an 81-pin configuration.

His fingers traced the sensor inputs. Pin 15 was the crankshaft sensor, the ECU’s sense of time and rhythm. Without it, the engine was blind to its own rotation.

Pins 1 through 4 were the ignition signals, the sparks of life, while Pins 6 and 7 waited to command the fuel injectors.
