Note: I have no documentation on the two empty indicators. They may not have been used.
Oil Pressure: 4-6 PSI (sensor grounded).
Fuel economy: light comes on below 3½" of mercury (sensor grounded).
Overdrive Indicator: bridges the solonoid, comes on when solonoid engaged (2-wires).
Low Washer Fluid: indicator comes on at 3¾" below the top of the reservoir and the washer is operated (sensor powered).
Temprature: Comes on at 225°('76 TSM) or 250°('77 TSM) (sensor grounded).
Note: With a 50/50 coolant mix the operating range is approx. -34 °F (-37 °C) to +265 °F (129 °C) with a 15 psi cap. All engines run a 195° thermostat and typically run 205°-215°F on a warm summer day.

Fuel gauge: only item fed from Constant Voltage Regulator (CVR), and the only gauge to need 2-3 minutes to warm up (sensor grounded).
