Hello I was wanting to add a second A/C unit to my torque t32. Anyone have any experience with this? The garage area looks to be pre-wired for this because there is a sticker stating the location of the second thermostat. So my question is it pre wired for power up to the roof vent? If so which one because I have two vents one over the garage and one over the bedroom in the front. Any help is welcome. Thanks
