I completely rewired my Charvel ST, Nailbombs, new pots, new Schaller megaswitch.
It wasn't difficult at all, and I'm a complete numpty.
Take your time, set your environment up properly (solder station etc), get your kids out of the way. Also this may be sacreligous, but the Seymour Duncan site has some pretty useful wiring diagrams.
Good luck, but you won't need it.
