Understanding ignition wiring on my 1970 Dart

67Dart273, thank you Thank you Thank you for taking the time to help me ferret this out! Understanding the flow of the electricity (direction) was a big help. I am really sure that pulling the plug kills the ignition (did it too many time for it just to be a coincidental jiggling of another piece), but moving down the line in your responses gave me some new things to investigate, partially based on what is relatively new on the car or has been recently refurbished (like the entire engine harness and all the bulkhead connectors) as opposed to all the wiring in the steering column including the ignition switch ( which only has 48 years and 200,000 mile plus on them)!

Again, thanks for your efforts, it could take a while to run down, but I'll send a PM when I finally find the culprit.
