couple of quick questions. Does it matter which wired button goes in a specific number on the breakout box? ie joystick goes in slots 1,2,3,4 and buttons 1,2,3 go in slots 5,6,7? How do I make one giant ground wire for all the buttons? Where do the ground wires go? and last but not least. What did you use to mount those breakout boards. It looks like a plasitc piece to keep the metal pins from hitting the wood, but I can't tell
