What kind of cable & connector recommendation would you suggest I use for my portable scoreboard project? I need ten conductors for six feet to connect a control box to a scoreboard panel. The LED power will require 12V/2.5A total (for all segments), but that will be split over two wires for pos (because I have two 1.5A power supplies) and one or two wires for gnd (depending on the wire gage). The for shift registers will require five volts and that will be carried on one of the ten wires as well (for a total scoreboard power of just under three amps). It will be connected and disconnected once or twice a week, and the conductors are exposed (but I don’t really need to worry about them getting wet because we don’t play in the rain).
A 15 pin [D-SUB connector like [this might work for you. There’s more pins than you asked for, but it would probably be a good idea to double up the power pins for extra current capacity through the cable you’re using.
With a connector on the scoreboard and another on the controller, you could use a cable like [one of these to connect the two devices.](Amazon.com)](https://www.mouser.com/ProductDetail/ITT-Cannon/DA-15P-A191-K87?qs=sGAEpiMZZMvlX3nhDDO4AKK985G3Qio0SQcysm2uW8w%3D)](D-subminiature - Wikipedia)
