2 questions - "Run" only power source/fusible link install

Run is what I meant. I call the positions of the key "accessory" and "ignition". Not the right terminology I realise, my bad. (I'll fix that up, thanks) The blue wire that runs between the ballast resistor and the regulator is the one you speak of correct? I see now looking at the diagram that that should be the one.

Ignition only power source for electric choke ? The choke should be hot in run. Dark blue at voltage regulator. Same wire where a isolated field alternator is or added. So if you upgrade the charging system you can take that dark blue to both places.
Again the dark blue at the instrument panels' main harness connector to feed gauges, hot in run.
