The Storm & Storm X Controllers were designed to interface via 2.54mm pitch jumper cables. This is that cable. Each cable is terminated by a connector on both ends and measures 30cm (11 3/4 inches) long. If you want to solder directly to your LED drivers, just snip off one of the connectors. Or cut one of these cables in half to have two ~6" cables with connectors on one end only.
Pro tip: Remove the connector from one end of cables by prying back / releasing the plastic retainer clip on the black connector housing. Then you can directly use the crimped pins to connect to the screw terminal blocks on your driver board. The factory-crimped pins provide better strain relief for the wire than just stripping and tinning the wire.
