Attention: TDR Forum Junkies 
I recently got this truck and one of the issues is the instrument cluster doesn't function except for the oil pressure. The previous owner added a mechanical coolant temp gauge (that was chewed through by rodents) run to the front of the head sending unit. I took the cluster out to see if was gummed up since there was a lot of gummy residue all through the dashboard. I did a bit of cleaning but made no improvement.
I am considering ordering a remanufactured cluster form an outfit that says they can match it to the old cluster if I understand correctly.
I have seen other forums where they discuss a variety of causes but thought I'd ask here.
One issue the truck had was the wire loom that goes over the injector pump area was worn through and shorting out #9 fuse if I recall correctly. I used a piece of heater hose to insulate it and that has seemed to cure the shorting problem that killed the motor intermittently. I am not sure if that might have shorted the cluster or not. The dash lights & hi beam indicator work.
I hope there is some advice to be had here. Thanks for any suggestions
