Batboard

Hello,
I have an old Motorola headset mic with pre amp. Part # TMN6090A. The only thing I can find on the internet is that it is from a Syntor X radio. Does anyone know the functions of each wire? I'm trying to wire this for another radio but need to know which wire does what. There are 5 wires; red, black, green, white and yellow. Any info would be greatly appreciated.

Thanks

Not sure if this will help but I found this for a TMN6067 which is the only SyntorX handset I could find.

Red - Mic Hi
Black - Ground
Green - Mic Low
White - Receive audio
Yellow - PTT
