Cleaning up wiring harness

[007brendan]

So, hopefully, I'll be switching out my rear taillight and turn signals with an integrated taillight this weekend.  I've already taken the rear fender, along with the entire rear undercover off, and I really like the look.  I've been toying with the idea of just totally removing the rear plastics, too, based on some of the other bikes I've seen on here.  But the current wiring situation underneath the rear plastics is just dismal.  It looks like a combination of heatshrink, zipties, electrical tape, and plastic conduit all thrown together.

Anyone have any tips or ideas (preferably pictures) for cleaning it up?
