CELECT PlusThe Cummins CELECT Plus electronic engine con-trols replace the earlier CELECT controls.Freightliner supplies two principal wiring harnesses toeach engine. The 12-volt (12V) engine harness sup-plies power to the starter and various appliances.The electronic engine harness communicates databetween the electronic control module (ECM), vari-ous data-gathering devices, and the cab informationsystems. In addition, a power harness supplies bat-tery power to the engine ECM.For a schematic of the CELECT Plus cab wiring, seeFig. 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 harnessand engine ECM end of the electronic engine har-ness, see Fig. 5. For a detailed view of the frontwallconnector end of the electronic engine harness, seeFig. 6.For a view of the harness routing for the FLB, seeFig. 7.For a view of the harness routing for the FLD, seeFig. 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 forthe FLB, see Fig. 12.For a drawing of the N14+ 12V engine harness forthe FLB, see Fig. 13.For a drawing of the M11+ 12V engine harness forthe FLD, see Fig. 14.For a drawing of the N14+ 12V engine harness forthe FLD, see Fig. 15.
