Default 3 prong tender pigtail

My Low Rider came with a 3-prong pigtail plug. Still only 2 leads to the battery though. Anyone know what this is for? I'm wondering if the previous owner needed it for heated gear or something.

When I first looked at the picture you provided, my first thought was a USB charging port. But, if there are only two leads going to the battery maybe not.

I am pretty sure that all the new bikes have a 3 prong. It matches up to the Harley Davidson branded tender. You can use the 2 prong tender with no problem.
What/where does the extra go? Good question.

I threw my meter on it. The rectangular connector goes to the positive lead.

I believe it is for using a branded HD battery charger rather than a battery tender.

Correct. The third terminal is for a voltage sense wire.
