on the control board there is a small white box that is right next to a larger black one. The white has RY5 on the left corner as you are looking at it from the top where all the wires are. Next to it is a larger black box that has two metal clips, prongs, however you wish to describe it. The piece that attaches to that area is on one side just a white wire and the other a white and red....each side separated and inside one piece that is plastic but again separated. All I need to know does the side with the white wire only go on the inside or outside.
