Ignition help needed (stumped)

Bugman, Yes. I got that from the pdf 67Dart273 posted.

edit: Here's what we see on the inside of the bulkhead.
This looks like the standard wiring arrangement.

So the question remains how is it connected on the engine side

Is the grommet with the red and black wires the 65 for the ammeter (65 amp alternator option) or something else?

What is unlear is whether the 65 amp wiring option had two parallel wires R6 and R6F,
or whether R6F replaced R6.
Below is how I thought the power feeds on this car connect based on the photos thinking the grommet was for the 65 amp option.

Because in this photo there is a three way splice.

I have to wonder if this was another fusible link.
or was this a hack.
