Is it possible to keep old style electronic VR with a dual field alternator?

Hi guys,
Just had all wiring harnesses replaced and restored instrument cluster put together in my 69 GTS. We weren't sure how to keep the original looking voltage regulator (which has electronic internals) on the firewall. So, my "friend" cut the triangle connector and doubled up the spade for the Ignition side of the regulator.? He thought it was working, but obviously it was not.
Using a dual field round back alternator since I'm running electronic ignition, which is hidden.

Problem is: not charging. Ammeter stays centered until eventually battery discharges. Voltmeter across the battery verifies same.
Is it possible to keep the original looking VR and use the dual field alternator? Not sure how to make the circuit work.

Im chasing my tail, reading the two different wiring diagrams, trying to figure out what the heck was changed! And of course, really trying to keep the original look. Any suggestions?
