I found information on the MD-9600 mic but unfortunately there were two conflicting pieces of information. I finally confirmed the correct one and have a schematic for the mic and the pinouts for the RJ-45 connector used.
Pin 1 - SW2
Pin 2 - SW1
Pin 3 - VCC (3.3v from radio)
Pin 4 - Ground
Pin 5 - Mic
Pin 6 - PTT
Pin 7 - NC
Pin 8 - NC
