I don't know what it is about wiring but it is hard to keep neat. I did a car that had a neat and clean wiring harness then I had to trouble shoot a short after the car was done. The lesson I learned was be organized but keep it loose. It is a lot easier to chase a wire if you don't have to cut a zip tie every 2 inches!
So here it is. It looks a little messy but it all works.
