How do people get their wiring so neat and tidy and organised? Every time I try it just winds up looking like the creature from the black lagoon. It's terribly distressing.
That's why you don't build your cab out of Plexiglass. No one will know!
Seriously, though -- the back side of mine are like an explosion in a wire factory. 37 buttons, RGB LEDs on each across the whole unit. That's 222 wires running to two controllers, plus four USB joysticks, a USB trackball and USB spinner, each with their own set of wires. There's no sane way to keep it all neat. I don't have any photos of the back of mine, but I basically cleaned things up by zip-tying things into smaller bundles and then zip-tying them together into bigger bundles. But its a giant mess, but no one would ever know looking at the cab, so who cares? With buttons only, you can buy a bunch of bulk wire, crimp connectors and heat shrink tubing, but its a lot of work that probably isn't worth it if you're not neurotic about wire neatness. (I have friends who would break into my house in the middle of the night and slowly rewire my whole cab if they knew what it looked like inside!)
Edit: I should add, having done LOTS of wiring over the years -- I'd rather have a less neat wiring job that had things with good color coding and labels, that something neat where every wire is the same color and nothing labeled. Nothing against some of the "neat" wiring in this very long thread, but when every wire is the same color, unlabeled and bundled together you have to end up cutting the bundles out if anything goes wrong anyway. As messy as mine is, every single bundle, every connector, every USB cord are all either tagged with labels from a label maker, or in some cases heat shrink tubing with printed labels. DYMO makes heat shrink tubing for their "professional" grade labelers. I used them a LOT building a couple cars, and used them on all the USB cables, and longer jumper bundles. (I have two ~50 wire bundles that get the LED wiring from the small CPs to the LED controller, which are zip-tied, covered with mesh wire loam, with labeled heat-strink on each end, for example.)
