Pin 2 is Ground
Pin 3 not connected
Pin 4 Transmit
See picture.

Looks like Audio is pin 1, ground is pin 2 and TX switching is pin 4.

Thanks so much guys. The ar-3300 i have keys up with the 4 pin mic currently with the radio but no modulation. Tried another 4 pin mic i have here (used on my galaxy saturn) and same results. Figured i would start by confirming the correct mic wiring. 73's thx
