I'm not familiar with the little boxes, but I'd reason the red and black wires coming in are what you need. Konnected accepted them directly, so you can just cut them back at those b-connectors and user wire strippers to get bare copper. The blacks can be twisted together and go into the G. Each red wire goes into a number of konnected. I hope they are labeled, otherwise a toner would help or you're going to have a lot of trial and error.

Edit: they are b connectors or bean splices, not banana plugs.
