Absolutely brilliant Greg! It took me a while to recognize that I was a visual-based learner, so seeing a demonstration is almost always much more valuable to me than reading a manual.
The only, very minor, suggestion I might make is when you are showing the Sure Power connectors (@ 2:08 mark) with color codes. You could draw lines between the key and the connectors rather than just relying on the color codes, in case someone is color blind.
