_Plus

The Cummins CELECT Plus electronic engine con-trols replace the earlier CELECT concon-trols.

Freightliner supplies two principal wiring harnesses to each engine. The 12-volt (12V) engine harness sup-plies power to the starter and various appliances. The electronic engine harness communicates data between the electronic control module (ECM), vari-ous data-gathering devices, and the cab information systems. In addition, a power harness supplies bat-tery 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, seeFig. 2andFig. 3.

For a schematic of the engine compartment wiring, seeFig. 4. For a detailed view of the power harness and engine ECM end of the electronic engine har-ness, seeFig. 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.
