I kind of wish it did turn on intermittently though, there's no way to get cold air through the vents without it.

I looked through the wiring diagram for the MT fr-s and here's what I found.

I still need to find how the main body ECU uses OT+ and OT- but my toyota had a thermistor as well in the circuitry that controlled the AC compressor magnetic clutch. Only reason why I know is because the car had an engine swap and I needed to get the stock HVAC system to kick on the new motor's a/c compressor.
