The DBX-9000 is a compact 9-wire connector and harness assembly for use with universal-style DCC decoders. It is designed to simplify the wiring connection between a steam locomotive and its tender, providing a quick-disconnect for painting, storage or service. Nine numbered pads correspond to the nine wires of the harness to be used for motor, lights, track pickups, and/or cam. The 9-wires in the harness use ultra-flexible wire to reduce any extra tension between the locomotive and tender. The center mounting hole accommodates a 2/56 screw.
