Turn on heated seat with remote start?
 

I have a 2009 Hyundai Sonata, which I have installed an aftermarket remote start in. The remote start has an auxiliary output, which, according to the manufacturer, can be used to power such things as heated seats, rear window defrosters, etc.. I was wondering if it's possible on this car to power the heated seat with that? The heated seat switch is a single button, which you press once for high, and again for low. A third press turns it off. Does anyone know how these work?
