If you ground the wire that plugs on the sender, the guage should peg.

It should have 5-6 volts on the wire that connects to the sender if it is hanging loose.

It is either red/white-stripe or white/red-stripe and operates the same as the oil pressure.

There is a separate sensor on the radiator hose neck that has two wires, this sensor is used exclusively by the computer and has nothing to do with the dash gauge.
