Cummins CELECT™ and CELECT Plus™ Engine Wiring
54.14 Specifications
CELECT™ Plus
gine wiring. See Fig. 19 for a detailed view of the vehicle harness connector.
The Cummins CELECT Plus electronic engine controls replace the earlier CELECT controls. Freightliner supplies two principal wiring harnesses to each engine. The 12-volt (12V) engine harness supplies power to the starter and various appliances. The electronic engine harness communicates data between the electronic control module (ECM), various data-gathering devices, and the cab information systems. In addition, a power harness supplies battery power to the engine ECM. For a schematic of the CELECT Plus cab wiring, see Fig. 1. For detailed (partial) views of the cab wiring, see Fig. 2 and Fig. 3. For a schematic of the engine compartment wiring, see Fig. 4. For a detailed view of the power harness and engine ECM end of the electronic engine harness, see Fig. 5. For a detailed view of the frontwall connector end of the electronic engine harness, see Fig. 6. For a view of the harness routing for the FLB, see Fig. 7. For a view of the harness routing for the FLD, see Fig. 8. For a drawing of the power harness, see Fig. 9. For a drawing of the FLB electronic engine harness, see Fig. 10. For a drawing of the FLD electronic engine harness, see Fig. 11. For a drawing of the M11+ 12V engine harness for the FLB, see Fig. 12. For a drawing of the N14+ 12V engine harness for the FLB, see Fig. 13. For a drawing of the M11+ 12V engine harness for the FLD, see Fig. 14. For a drawing of the N14+ 12V engine harness for the FLD, see Fig. 15.
