Piece of cake here (sorry, dun it before :) )
Pin 2 - Mic Audio (Pre-emphasis)
Pin 3 - PTT (pull to ground to tx, works with link-comm_
Pin 5 - Flat TX Audio (no pre-emp)
Pin 7 - Ground
Pin 8 - CSQ or CSQandPL detect (CSQ and PL detect only works if
microphone H.U.B. input is grounded)
Pin 11 - Discriminator audio (may also be de-emp audio, changed by
jumper on logic board, I forget which one, maybe JU551)
Pin 1 and 16 - Speaker audio (neither lead should ever come to ground,
balanced audio)
NOTE - 8 Channel models, accessory pins are NOT programmable, the 16
channel units are much better.
On front mic plug, pin 8 is "handset" audio (low level speaker audio)
I hope that helps you out. If you have any other questions, you can
write direct or here.
