Ignition system, battery to starter/solenoid

"ACC" on the older cars is going CW, left to right, LOCK (column switches) -- "ACC" (runs radio, etc)--OFF--RUN--and START

ACC is all the "accessories" that are on either with key in "run" or "acc". Radio, heater motor, etc.

Yes, "run" is "ign1" and "ign2" is the brown ballast bypass circuit.

Another note, some diagrams incorrectly diagram the "start" and "bypass" circuits and suggest they are the same circuit. They are not. They are as I noted earlier separate switch contacts, in order to isolate them as I explained

EDIT I guess I screwed this up, it's (from left) ACC--LOCK--RUN--START. It's "new GMC" that is "LOCK" at far CCW
