An electro-mechanical connection is provided for transmitting power to one or more light sources affixed to the shelves of a shelving system. The connection eliminates the need to run wires the entire distance from the light source to a source of power and enables efficient and accurate coupling of the components. This is achieved by provided a slim track strip extending the height of the shelving unit and a specially designed twist connector for tapping off wiring harnesses from the slim track at the level of individual shelves where the harness leads to shelf-mounted light sources.
