Hew, remove the face of the evaporator(outlet duct)to gain acces to the evaporator coils. Drill a small hole in the side of the case to insert the tube and run it accros the front to center. Then insert the end of the tube into the center of the fins the depth of the evaporator(approx. 2").
This should be the coldest portion of the unit and the most likley area to freeze. This will switch the compressor off based on the rheostat setting before freezing.

The Smiths fuel gauge requires a voltage stabilizer to pulse a constant 10 volts to prevent the gauge from fluctuating when alternator voltage varies. I have VDO gauges which do not require this part.
