Bulk head connection issues

Every year is a little different but this is fairly typical for mid to late 60s.
A is Battery output and recharge line.
R is Alternator circuits. R6 is alternator output.
J1 sometimes is power to ignition switch
J2 is ignition (includes power to voltage regulator)
J3 is ignition feed when key is in start.
Q2 is accessory feed. (pretty much everything which requires key on other than ignition)

RWO are the letters Chrysler used in the books for the mid size Plymouth and Dodge models. So the way to read the (16DBL-RWO) is that Darts and Valiants will have 18 ga wire and mid size models will have 16 ga wire. That's from the '67 Plymouth shop manual.
