WOW--What incredible work...
I did my first harness this year and the one thing I would do different is using a pre-made pigtail.
I would be happier with this fusebox than the one i made and wired myself.
There are cheaper alternatives on ebay and other sources

Also the sideways pictures can be solved by opening the picture in "photos" for windows or something similar. It will probably show the correct side up, then just crop off the slightest edge of the photo and save it, then re-upload it. All of my pictures off my iphone do it.
