I went looking for the accessory socket and found it under the tank, right where it is supposed to be. However, I also found another electrical connection under there. It is gray, two wire, and has a wire safety clip. My tank hasn't been off in hundreds of miles so if this is something I disconnected and forgot about it's obviously not required for the bike to run. I can not see any place where this might connect. ????
Looking into the end of the connector. Poor quality phone pic
Side view, better pic this time
