The second connection is an overflow for a float switch safety. The switch shut down power to outside unit if the trap stops up keeping the house from being flooded. Russ

When you install the trap just break the yellow wire going to outside unit. If no more questions please rate me 3 stars or higher. Any lower I do not get paid. Russ
