push button start

The idea of having a push button start has intrigued me, and now im wondering what is need for this to happen. I'll be switching from stock wiring harness to either painless or ron francis. I know i'll need a push button (momentary) switch and another switch for ignition (power). so what else do i need. anyone know if ron francis already has this setup in his kits (when choosing column or dash ignition)
