4WD wiring diagram needed

Truck listed above is the LT model.

Does anyone have a wiring diagram for the 4wd front axle actuator and transfer case motor? Every once in a while the actuator motor works. I replaced it and still the same problem. I replaced transfer case motor and still the same. The light on 4h button blinks then goes right back to 2h. I checked transfer case fluid level and it is just below the fill plug.
