Thanks for getting back to me so quickly!

Correct - Typically though with the simple A/C system of the yaris, almost the entire time the button is pressed the compressor is engaged.

For the transducer you can measure the voltage on the grey wire with the AC on and you should see between 0.76 and 4.74 volts.
