Sportster Wiring

I had to look up some wiring diagrams so I could figure out a couple of things and I found this diagram. I did not realize how simplistic this bike really is. I am so accustomed to computers and heavy electrical influence on a bike or car that I forgot how simple it really can be. I think this image I found is a great way to describe it. I would love to credit the creator, but I am not sure who did it.
