It's on 09' CVO Ultra and he is using the dash/faring mount. The port and weather proof cover I circled and the cover is # 14
He has the supplement 2011' CVO service manual and it dosn't list what the wire is used for or where to install it. I was hoping someone
with a new 2011' CVO Ultra had spotted it hanging along the front brake line or another wire.
It's not too long, so it cant go to far.

I'll go look and see what I can find out. Might be a little bit before I can come back with any useful info. Your last post clarified everything.

So I looked, and I don't see that connection, but then again I don't necessarily have the CVO one to look at. All I can do is compare notes with the stuff I had added to my limited.
However, I went and looked again at your original post. I'm a bit confused again. You said " The kit comes with a plug in charger that you can charge the 660 on or off the bike."
As far as I can tell, I have the charger that can be plugged into the wall and charge the zumo and isn't used to charge it on the bike. When I plug the zumo into the mount, it charges. No need for an aux charge port per se. The interconnect harness usually plugs into circuit 29B. Maybe that cable is there to facilitate this depending on your wiring requirements? What color are the wires?
Sorry I don't have the exact answer for ya, but I'm definitely very curious to the final answer.
