I've about run out of ideas/info. The Francis panel is sealed and I can't determine where each terminal goes after it ducks under the cover.
I think the best approach at this time is to abandon the original ignition switch in place and use the RF switch in an inconspicuous location. Just wire the car per the provided instructions and forgo the nostalgia. Reliability will trump again. Dang.
Thanks for the help. Really appreciate your efforts. Sorry we couldn't crack this nut.
