Find one in a junkyard and take the harness out of it?  Or phone/email used part places?

 

And only the 4wd harness is melted?  That's...unusual.

 

As for finding the harness, it'll be the bundle of wires with connectors on the transfer case, and if it's similar to the full size trucks, goes to the front diff, and a plug in the fuse box in the engine compartment.  There may be a separate one, or it could continue on into the cab to connect to the electric buttons or a computer somewhere.

 

I would suggest getting a short term subscription to the full-service manual for your truck, it will have the wiring diagram for these systems, routing of the wiring harness, stuff like that.  places like alldatadiy.com, helminc.com and other sites....
