I have a thermal zone air conditioner and the dogs chew the wirers apart. I can color coordinate most of the wires hoeever there is a brown wire coming out of the hose with the rest of the wirers, however there is no brown wire running from the air conditioner unit out side, what do I connect it to? The rest of them are all connected. Blue, white, yellow, green, red, at there thermosatat there is a orange and brown wire, but when the wires run out of the house, there is not an orange wire, only a brown one, but from the unit outside there are no brown or an orange one, so me question is the brown wire coming out of the house connects to what other color?
