I was removing my Bose Wave Subwoofer to replace the amplifiers inside. While doing this I noticed in addition to the wide green wiring connector going to the system there is a smaller grey connector on the bottom of the subwoofer. Does anyone know what this plug goes into or what it is for????

 

Diagnostic plug?

 

I hope that is what it is for? Are you asking or answering? I cannot find anything it plugs into.

 

I kind of remember reading that a long time ago but have nothing to back me up with thats why I put the question mark.
