Does your temp gauge work the fuel and temp gauge share a common connection if one is bad it messes with the other.

Don't feel so bad, my 78 gauge cluster works when it wants.

I don't think he does feel bad. He stopped complaining in 2011.

For your issue have you verified you have good connections and clean grounds? Most electrical issues are ground connection relayed.

Not yet. The "dash" torque screws are rusted to the point they're mostly gone. Winter project. It rounds and drives now, minus the junk transfer case that's way past bad. Sounds like trolls hammering through the floor

Where is a reliable wiring diagram available?
