no idea. I just have an on/off aftermarket switch on the dash. I'd like a proper switch for th eunit if one exists - I assumed it would have a thermostat switch similar to a propex?

I have one of them if you want to buy it?!? Do you have the thermostat it the ducting?!? That control the temp of mine. It turns the unit off when it gets to temperature and back on again when it drops. It's controllable via I pull knob under the passenger seat.
