1 - Audio
2 - Receive
3 - Transmit
4 - Ground = Channel Down, 22K Ohm to Pin 3 = Channel UP (was originally listed as 2.2K, a visitor told me it was wrong)
5 - Ground and Switch common
6 - 13.8 Volts. SEE CAUTION BELOW


CAUTION: Shorting-out Pin #6 can cause damage to radio! If you decide to install a new mic, we strongly suggest you remove pin #6 from the mic plug to avoid any possibility of a short!

Hope this helps... Best I could find for ya...
