I looked on my elec manual. That indeed is antenna for security. No go to use. The p&a definitely uses the dlc connector. I would personally use the 2 wire charging connector for a battery tender. It's fused @ 10 amps. Just unplug accessory when needed to use the tender.

 

This is the official power add-on pigtail for the Street Bob. A must for installing garage door opener. I tried to post a pic but it didn't work for me right now.


Electrical Connection Upgrade Kit-72673-11

Part Number 72673-11

 

This is what I'm going to use. Thanks for all the help guys.
