where can i find wiring diagram for a 2004 H.O cummins engine harness

Ok, I will see what I can find at work
looking for fan clutch, cam sensor and crank sensor wiring to be exact.
keeps setting a code for the fan clutch and cam sensor and both have been replaced but still sets those codes so I need to check wires back to ecm to verify they are good.
thanks for your help.
