Wiring Harnesses
Usage:
The ECM uses integral 40-Pin Deutsch Connectors (J1/P1 & J2/P2) and the Customer Connector (J3/P3) to interface the engine electronics to the customer wiring harness. The control system has been designed to operate on 12 VDC or 24 VDC electrical systems. The control system is protected against jump start conditions and short circuits to the battery. Minimum voltage requirements and maximum current draw for the engine control system are:
As stated previously for ECM connectors J1/P1 and J2/P2, and all unused J3/P3 Customer Connector socket slots must be filled with plugs to ensure proper connector sealing.
