Electrical problem with the dash.
This wiring problem can be much more costly, and time consuming, than you want to take on.
Professional mechanics cringe, when a wiring problem of this magnitude comes their way!
It's probably a bad ground for the instrument cluster.
The instrument cluster housing is plastic. There is a flat, thin, 2 to 3 inch wide, piece of plastic that is the wiring harness for this instrument cluster.
In this flat piece of plastic, are thin flat copper strips. These are like wires, to conduct the electricity to the gauges, lights, and the rest of the instrumentation.
Since the plastic instrument cluster is not metal, and therefore it can't be used as a Ground source, the flat piece of plastic I mentioned above, has a Ground wire to it. May be more than one.
This ground wire/s could have corrosion on the terminal end, where it attaches to the truck body.
Bad ground, everything goes haywire. The ground wires, might loose on the terminals used for the flat piece of plastic.
Another source of a bad ground problem overlooked, is that the cab of a truck receives it's,
Main ground from the engine.
There should be Two ground straps, coming from the firewall over to the engine. Sometimes, when the upper part of an engine, or the engine is replaced, the mechanic neglects to reinstall these ground straps.
Sometimes just one ground strap is reinstalled, and this is No good!
Also both terminal ends of these ground straps are a good source for corrosion to develop.
Corrosion makes a bad contact.
I myself would take the truck back.
