This is a major shot in the dark but I bought used a set of the Sena 20s clamp kits that include the HD 7pin for use with an Ultra. Part of the kit is supposed to be a little piece that clips on if you are NOT using a 20s to make the contacts complete allowing use of just the bike like a wired headset. (Center left of the image, just looks like a black square).

Unfortunately for me the seller never disclosed that he had lost those and Sena doesn't sell parts so I'm up a creek.

Anybody else possibly not ever use it in that configuration and have this piece sitting around?

Thanks!
