You won't find a separate part number for the wiring, you're going to have a make your own harness to make it work.
I'm in the process of gathering parts to do this as well. You'll need more than just the transfer case and module -
-Transfer case
-Transfer case control module and bracket
-Rear propeller shaft
-Rear locking differential
-Differential control module and bracket
-Rear axle shafts
-Switch on centre console
Part numbers are all dependent on your production date and engine.
You'll have to follow the wiring diagram and wire it exactly as it shows. The modules talk to each other through the CAN-Bus.
