My son has a Kenmore 106.59292994 model Refrigerator. I went to hook up the water line for the ice maker, and noticed 2 pieces of tubing down near the front where the Filter is located. One tube looks slightly larger than the other, and the second one goes up the freezer door hinge. I noticed when we pushed the water dispenser, water came out of the larger tube.

Could someone tell me how these are connected, and where please? I am guessing they get connected together, but there is no connections for either of them.
