An elongated polymeric ribbon is mounted to the cabinet of a refrigerator/freezer or the door and at least one electrical conductor is integrally formed in the ribbon, which also integrally includes at least one fluid conduit. In one embodiment, the ribbon is mounted in association with an elongated spine, such that a module can be mounted anywhere along the spine and coupled to the polymeric ribbon for receiving operating utilities therefrom. This system provides the manufacturer with the capability of positioning a module requiring operating utilities at any desired location within a refrigerator/freezer cabinet and/or on the doors of the refrigerator/freezer. The ribbon connector is accessed by connections which allow dealers to customize refrigerators for individual consumers.
