Connectors The DMMF interfaces to the engine and vehicle systems through two 23-pin AMP connectors. The Woodward part numbers for these parts as well as the actuator connector part number(s) are located on the plant wiring diagram (Figure 1-5). The part numbers also list the pins required for the 23-pin DMMF connector. - Page 14 50 mm (2 inches). The other end of the shields must be left open and insulated from any other conductor. DO NOT run shielded signal wires along with other wires carrying large currents. See Woodward application note 50532, Interference Control in Electronic Governing Systems, for more information.
