When using the factory schematics, get yourself a set of colored pencils. Highlighting the lines will make it alot easier to follow.

I am a bit of a nerd. Printed the electrical pages to pdf to reduce the size then put them in my tablet and opened with a paint program so I can use a stylus and draw on them. Have a set I am erasing as I go so I don't miss anything.
