Also, the hot connections to the tone pots should be on the right side lugs instead of the left ones, as the way the diagram has it the tones will be at max on 10 instead of 0. There is also another way you can wire the neck tone series/parallel push/pull so that it bypasses the 3-way setting and instantly gives you bridge and neck in series from any position, if that's an option you'd prefer.
