I have figured out the pinout by taking apart my handset. Here it is:

*-Down button (12V to activate)

*-Up button (12V to
activate)
* -PTT line (ground to transmit)
* -GND

*-Mic-level audio *-12V power (regulated to 5V inside
handset)

(looking at the male connector on the radio)

Sorry if that's hard to see. The asterisks represent the pins on the male
connector.
Hope this helps anyone else who's looking for it!


Do you mean this? (My attempt to understand your diagram)

1
2 3
4
5 6

1 = Down button (12V to activate)
2 = PTT line (ground to transmit)
3 = Up button (12V to activate)
4 = GND
5 = Mic-level audio
6 = 12V power (regulated to 5V inside handset)
