How to setup the operator console io

So now that build seasons over, I’ve decided to start work on the operator console. I was hoping someone could share their experience in this area. I have two questions:

  1. Do you have to use a breadboard, I recall reading that, but can’t find it anywhere in the rules…
  2. Anything wrong with just doing it like this with jumper wire and capping the grounds together?

Edit: 1 more question, anyone know how to get the buttons on the driver station io tab to work?
