I've found that almost all the electrical connectors (not counting simple terminal ends) used on a Harley are easiest to obtaine through a dealer. While a few electronics places have the connectors it usually turns out they only sell them in quantity. The connector your in need of will be in the parts book. Then you have an option of going through your dealer or using one of the discounters on-line. I'm sure that if you go on-line the shipping for such an inexpensive part will be more than the savings on the part. I'd really suggest you just go to the dealer.
