I have three low voltage wires going to the condenser. Two were pulled out red and black, the third (white or clear coloring) is attached to a red pig tail coming from the controller. A second pigtail from the controller had nothing on it and looks like has never been used although the wire was stripped with no protection over it. This a Goodman condenser so do all three wire tie onto the one pigtail?

On a strait A/C outside unit you only have two low voltage control wires.
