Can someone verify this? I have read just about every article on upgrading the vr on the early single field alts. Here's what I have. 66 Charger, 440, Msd ignition, dual field alt with one field set grounded to case, (converts to single field alt) My stock wire harness has 1 green wire and 1 black wire. Green to field, black to batt, at the alt side, on the original vr there is a blue wire with tracer (ign side) and a dark green (field side). On the p3690732 there is a stud post in the center and a red wire with a connector, (no instructions) Question is what wire to what on the vr side and do I need to ground the vr?
