100-7765     Required for the replacement of (S/N: 7LG) Engines    A Wiring Harness Adapter is required for the replacement of a 3176 Truck Engine with a Remanufactured 3176B Truck Engine. The Wiring Harness Adapter adapts the OEM Vehicle Wiring Harness to the ECM 40-pin OEM connector. All wires that are required are included in the Wiring Harness Adapter. All wires that are optional are also included in the Wiring Harness Adapter. A data link connection pin for the ECAP is designed into the Wiring Harness Adapter.Note: The ground wire for the wiring harness must be installed on the ground stud for the cylinder head.Refer to Illustration 1 for the schematic of the Wiring Harness Adapter. Refer to Table 1 for the part numbers of the Wiring Harness Adapter.Engine Monitoring Package

Wiring schematic of warning lamp for Engine Monitoring PackageThe Engine Monitoring Package is optional. A warning lamp must be installed in the truck cab for the Engine Monitoring Package.Note: If you are replacing a 7LG07500-UP engine, warning lamps for the Engine Monitoring Package may already be installed.Note: The "" lamp and the "CHECK ENGINE" lamp are not the same lamp.The engine monitoring package can be programmed to OFF, , DERATE or SHUTDOWN through a programmable parameter from the customer. Refer to the Electronic Troubleshooting Manual, SENR5582, "3406E/3176B Diesel Truck Engine" for additional information on programming customer parameters.Refer to Illustration 2 for the wiring schematic of the warning lamp for the Engine Monitoring Package.Coolant Level Sensor

1500 mm (59.1 inch)    The coolant level sensor is optional. The coolant level sensor can be installed in the radiator top tank or the tank for the shunt. The coolant level sensor is ENABLED or DISABLED through a programmable parameter from the customer. Refer to the Electronic Troubleshooting Manual, SENR5582, "3406E/3176B Diesel Truck Engine" for additional information on programming customer parameters.Note: If you are replacing a 7LG07500-UP engine, warning lamps for the coolant level sensor may already be installed.A wiring harness must be fabricated in order to connect the 4 pin Packard connector on the sensor to the OEM Harness Connector of the Wiring Harness Adapter. An extension harness for the coolant level sensor can be purchased from an OEM and the extension harness can be modified for installation. Modify the extension harness by replacing the OEM Harness Connector of the extension harness with Deutsch sockets. The Deutsch sockets plug into the OEM Harness Connector of the Wiring Harness Adapter.Refer to Illustration 3 for the schematic of the coolant level sensor. Refer to Table 2
