1999 pete 379 d60

I've got a 1999 pete 379 with detroit 60.
Cruise and Jack's inop. Computer shows clutch switch on. So the clutch switch is under the cab below the clutch. Sensor is there but the pigtail out of the harness is missing. I have a wiring schematic but I'm pretty sure it is incorrect. Hopefully someone can supply a correct schematic or help me with the routing of the wiring as in which direction the wires would come from in the harness or color of the wiring maybe which harness it is located in, there is 3 small med large groups of wiring
