CUMMINS ISX Wiring Diagram Manual

OEM INTERFACES CM570 ELECTRONIC SUBSYSTEM TECHNICAL PACKAGE Cummins Engine Company, Inc. Page 1 WIRING DIAGRAM Layout. The CM570 Electronic Subsystem Wiring Diagram is organized into four sheets. Each sheet is one-fourth of a single, continuous wiring diagram that defines every OEM interface to the CM570 electronic subsystem. The diagram attempts to organize the components by location and interface. Actual locations may vary. a. Sheet 1 shows every possible interface to the 31-pin OEM connector. b. Sheet 2 shows every possible interface to the 50-pin OEM connector. Sheet 2 also shows interfaces to the Water-In-Fuel (WIF) disconnect, the Engine Brake Relay disconnect, and the Electronic Air Compressor Governor (E-Governor) disconnect. c. Sheet 3 shows interfaces to OEM components typically located in the vehicle cab, except for the dashboard. d. Sheet 4 shows interfaces to OEM components typically located in the dashboard.
