OK, mystery solved. Went to my local HD dealer, they pulled a set of the exact same bulbs off the shelf, and packed inside were two adapter cables to go from the bulbs with the new style connectors to the wiring with the old style connectors. Apparently somebody just forgot to pack those cables in my headlights box. Dealer took care of me, and gave me the adapter cables out of his box, no charge - great service!
Well...a lot of somebody's didn't pack a lot of adapters in a lot of the boxes it looks like...go figure. I bought mine online from a dealer in Colorado and I don't live in that State or I would've probably gone to see them...good job!
