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

Thanks Guys, question for Mattax,
I understand about grounding the other alternator field.
Am I loosing anything by reverting back to single field? It seems the dual field is better for the electronic ignition. Would it be best to try and hide the flat type regulator somewhere and keep the 2 fields if I cannot integrate this original looking regulator??
My friend cut out the triangle connector and thinks he put both on the spade into the top (ign) regulator. I have a good 69 Dart wiring diagram (attached), but need to UNdo the mystery splice, find out what colors and where the original triangle connector was removed, and then retrace the steps.
I have been really trying to keep the correct original look and would hate to loose it now.
Brief history...(I ordered all wiring harnesses from Laysons and had them directly shipped to my friends place, where the car was being put together, so unfortunately, I never even saw the repop harnesses from the start).
Just got the car back the day before Carlisle PA, so its all new to me also.
Thanks for your help!
