Wiring all hanging out. I need a manual. This unit came along side a used trailer we purchased. Sellers said it came off the home but we dont know that. We just installed it and we get no fan coming on or anything. We do have electric going into, our thermostat is down to 63 degrees. We noticed a wire cut thats running into the fan part and no wire coming on a compasitor, actually the two nipples hanging down has one side with two red wires but .... We need a schematic.
