3 Vacuum hoses to ac switch

I recently replaced my heater core. When i did i took apart the ac box. I have put it back together but notice my vehicle is ideling so bad now. I was wondering if its got anything to do with the 3 hoses that come from the vacuum switch that is part of the ac? I know one connects to the rh kickpanel. Where do other two go?

I have no idea where they are routed; but that is the source of your rough idle. The disconnected vacuum line is in fact a vacuum leak.
