REAR STRUCTURE 6V2249 - Caterpillar

Be sure to use unshielded, twisted pair wire for this cable.
Specific machine engine applications will require different components and different connections to complete the wiring. Some applications may require Pins 14 and 15 to be connected to a right turbo inlet pressure sensor or a connection to Pins 27 and 28 to provide a ground level shutdown switch input. Refer to SENR1026 Schematic - 3408E and 3412E Engines for Caterpillar Built Machines - for the pin numbers and wiring connections for the engine.
Electronic Technician Dynamometer Mode
The Caterpillar Electronic Technician (ET) service tool can be used to perform a dynamometer test on a 3408E and 3412E Machine Engine. Running the test with Cat ET can reduce the need for extra sensors and wiring harnesses. The engine software may need to be updated to enable this feature. Refer to Power Connection video and handouts for April 1999 (LEVN4628) for additional information.
