K&R has some nice wiring systems, also Digital Delay has them also, I am going to re-do mine soon, and I am leaning toward the Digital Delay switch deal, they have a stand alone with the fuses and breakers mounted in the swutch panel, and you don't have to have the relay board, to wire everything to.
Check them out, they are a little more pricey than the ARC stuff, but I don't know if they are any better.
