This document provides a circuit diagram and component list for an engine control system. It includes labels for the engine control module and 48 other components in the system, including sensors, actuators, switches and electrical connections. The components are numbered and organized with descriptive names. The document also indicates how to identify individual cylinders and provides a terminal arrangement diagram for the ECM connector.
