You are right on the money Charlie. Those browns, if I recall, one of them goes to the fuse box, the other goes to the connector for the dash (the loom?). That still dont explain the function of that green wire and that "dead" terminal on my ingnition switch.
The general feeling I am getting is that everything is hunky dory as far as the wiring goes. I may have a bad ignition switch though. I will contact the guy I bought it from and ask if there was any problems with the dash lights and/or find another ignition switch and ohm it out to see how it compares with mine. That terminal ought to do something in at least one of the key positions.
Hope I havent dragged this out too long Charlie!! I sure do appreciate your help ! I know there are plenty more interesting hotrod topics than that little green wire on your ignition switch! Thanks...
