69 dart wiring issue?

I want to help but I'm not sure I can. I dont have a 69 or a 74 cars or those manuals.
All I can tell you is what I know. Originally there was a little blue wire that fed 12 volts at switch on to the top of the original voltage regulator. So when the factory needed another similar wire for the isolated field altenater they went back up under the tape on the wiring harness where it cant be seen and bonded another blue wire to the one they already had.
When they needed yet another blue 12 volt at switch on for electronic ignition they did the same thing again.
Someone else will have to help you determine what is what in those pics. I can't.
Good luck
