Wiring is one of the most time-consuming steps, and it really demands a lot of experience. Things that seem simple to me now, like how to use a single ground plane for your entire system, were very foreign when I wired my first soul cycle. When I wired that one, I though each circuit needed its own ground wire to the negative terminal of the battery. This means I was running many feet of wire that were redundant. Trial and error is really important to developing good practices.

The big fat connectors are 8-way connectors from Neutrik. This means that with a single twist lock motion I am connecting 8 different wires to each other, and allowing 8 different circuits to function.

Why would you want to use connectors in the first place, let alone 8-way connectors? Because, presumably, you're going to want to remove your Soul Cycle from your bike at some point (perhaps each night after you've used it). Having a quick-disconnect capability that separates the controls from the main cabinet means you won't have to be walking with one big rats nest of wires. you can undo the connectors, coil the wires and lift the cabinet off the bike for storage or service.

Same with the batteries. It's nice to be able to charge them with a quick-connect charger.

The more complicated the system you're trying to build, the more crucial it is that you start on paper. I drew several drafts of the wiring system in my notebook before moving to full sized paper.

The wiring step also encompasses coming up with elegant ways to pass the wires into the music cabinet. By this point in my project, I was getting a strong tropical fish vibe from the cabinet shape. So I decided to accentuate it by passing the wires into the cabinet near the 'mouth' of the form to give it a whisker-like appearance.
