Had the stereo and climate control out for a couple of days and when I went to put it back in there seem to be 2 extra wires on the auto climate unit. On the right side next to the tube that connects there are 2 yellow wires with round plugs. Do they connect to each other because they have matching plugs or where else do they connect to?? I didn't connect them to each other for fear that it might blow something.
