Thanks Brian, that was basically what I was thinking to do with the relays.
Looking at 50amp cont duty relays seems like this bosch would be the best bet:

Any other relay suggestions? I have all of the wire needed to do this,and would probably direct solder the main wires as I have never had much luck with crimp connectors handling any sort of load. I guess I could solder some good bullets to the relay!!!
