Since this seems a good time to criticize some of your stuff, or maybe it's a character default of mine, but I am much more anal about cleaning than you are. I think you could do a better job. I don't leave any grime in the corners or greasy residue on surfaces.
I would put more wire ties and maybe some tape on the insulation. The insulation seems to be a good idea but if it gets bumped it will move.
Never memorize something you can look up.
