Where on the battery does BSD (Bit Seriel Data Interface)connector attach? on 2006 BMW 325i

I had a battery installed at Firestone about 9 months ago and the BSD connector is not connected to anything. As I have recently learned,the new battery should have been "registered". At this point I do not know if they have the meansto do this. Why would they leave the BSD unconnected?

call and ask them why and can they fix it
I just got back from Firestone, they don't have the foggiest idea where the BSD is supposed to connect, do you?
