Not only is this a direct replacement for the Stealth Vacuum Brush (Part # 154 in the Stealth exploded diagram), it is also a good replacement cord for many central vacuum cleaners. On The Stealth, the black wire goes on the right side when standing in front of the power brush. Cord is 39 inches long. Exposed end of the wire is only wires, not metal tipped. Wires only hold better and last longer than the metal tipped version.
