Squareback Connection to Electronic VR

So, it looks like the "F" post on VR is connected to the ballast resistor to get switched battery power.
Based on your description, it does seem that the pigtail colors confused whomever was wiring in the regulator.

This is what I drew based on your observations 1 2 3 above.

Should I disconnect the Blue wire from the "F" post and connect it to the Green wire attached to the "I" post?
Hate to say it but I'd just start over and remake the Ignition and Alternator Field circuits. Too many splices, color changes, and not sure of wire size or condition.
I might even get a regulator pigtail with the standard Chrysler color identification of blue to I and Green to F. Or at least get some colored electriction's tape and remark it.

Connections should be like this.

Using standard Chrysler Colors:

Where the ignition-run wires connect to each other is not critical.
Route and join them as the best works with the layout in the engine bay.
This would be OK and may be what the person was trying to do.
