If you are asking me, I have no idea how to do it; I got the idea and information I used from "The Corvette Forum" internet site. When I mentioned a 6 volt Ford unit, I was referring a unit we would design from scratch and build from available components. The actual work would have to be done by my partner, who is the electronic brains behind all of this; I'm just a "car guy" with some off the wall ideas.
