Take the wire connector loose from the temp sending unit on the engine. Key on, any voltage on that wire? Usually the sending unit controls resistance to ground. If you touch that one wire to ground, key on, the gage should move, don't peg it or use a resistor.
I haven't found a wiring diagram on that, yet. Not sure of sending unit location?
