1971 Slant-six ballast resistor ID

Good morning buddies..

My alternator is Chrysler made, but has been replaced by a precedent owner.
It's a more recent squaredback type.

So, two field terminals.

... and connected like that :

And J2C wire (connected to the alternator field) is dark blue with a white tracer.
No white tracer on other J2x wires.
The junction of J2 and J2B dark blue wires is located onto the ballast resistor connector.
So, now, just have to restore the connectors and relocate the ballast resistor onto the firewall.

Thank you all for your efforts, you are the best...
:thankyou:
