Bose Series 1 9 pin aviation headsets

[Tmarsha]

Folks, I acquired two Bose series 1 aviation headsets like new. These have the 9 pin connector and usually connect directly to the power unit mounted in the panel with the on/off switch and volume control. Bose said they use to supply a portable cable assembly with a battery but no longer. These have the clear windows on the earcups. I would love to use these long term but only have one power unit and no ribbon cable that connects to the back of the power unit. Does anyone know where I can find the power units, ribbon cables to wire in the panel, or the portable cable assembly with the battery be able to connect to the existing headset jacks on the panel. I have called some avionics guys, looked on the internet with not much luck. Any suggestions is appreciated. Tks Tom

Got any schematics of how they should be wired ?  Take some pics and we'll see if the connectors are available and make them up.

Were these not part of a panel installed unit found on some of the Diamond series airplanes. I remember reading about these units somewhere.
