This is somewhat related so it is not a complete hijack but:
I too am looking to possibly bite the bullet and do a complete rewire. I have looked at kits from painless, ezwiring, and
www.hotrodwires.com. The EZ wiring mini20 seems like the way to go at $130, but I can't tell from their (super crappy) website if it comes with everything that the painless kit does. For instance, I can't tell if it comes with some sort of bukhead connector, or if it just has a fuse box. Has anyone ever installed the EZ wiring kits?
Also, FWIW, if you do purchase a kit from EZ wiring, I would still have a real nice look at (and possibly print out and use) the wiring instructions that are hosted on Painless' website at:
http://www.painlesswiring.com/Manuals/90504Manual.pdf
It seems to be extremely well written and is so detailed, it almost has me thinking that this job will be a gigantic PITA.
