You certainly are enthusiastic!
Each pot has 3 pins: ground on one side, +5V on the other, and the wiper (center) which gives out a voltage between 5V and ground depending on how far it’s turned. So if you want to put all the pots in one box, you’d just need one wire for each pot’s wiper plus a 5V wire and ground wire (which can be run in series to all the pots)…that’s 9 wires in total. So a something like a VGA cable could work, if you want to use D-sub connectors.
Look at the schematic in the back of the assembly manual to see how the pots are wired.
