Are you refering to the auto-locking hubs, differential,....? Can't get the diagram for you, but I may be able to tell you where something is or how to test/replace it.

I got the diagrams. Oh wait you have 94? I don't know for sure about that old of truck. But chances are I do have it somewhere in the archeives.I will go look later today.
