design.
The wax pellet uses electrical heat to melt and expand, very similar to the way the coolant thermostat operates.
DC motors, LEDs, and diodes require the wires to be connected to the proper polarity wire. A resistor (as in the heat coil in the actuator) or filament light bulb does not have an "in" and "out" wire. Connect one actuator wire to ground, and the other to a +12 source, and you should be good to go.
