Now you can test the accuracy of Fuel, Temperature, and Oil Pressure gauges, plus verify output from the Instrument Voltage Regulator.
The slide switch lets to test the gauges at high, medium, and low readings. The Power LED will flash if you are using a mechanical regulator, or glow continuously if you have a solid state regulator.

It's very easy to use.  No need to access the gauges or disassemble the dash.  Just unplug the sender, and attach the red lead to the wire you just unplugged.  Attach the black lead to ground.  Set the switch. Turn on the key, and read the gauge.
