Hey, thank you very much Keith! From the info you gave me, here's what I was
looking for:

RJ-45    Round    Function
-----    -----    --------
  1        2      +8 vdc
  2        3      Freq up/dn
  3        8      AF out
  4        5      PTT
  5        7      Mic gnd
  6        1      Mic in
  7        6      Rig gnd
  8        4      Squelch switch

I hope this chart will be of use to others.

I neglected to mention that I already bought the OPC-589 on the
recommedation of my buddy, for those of you who suggested that I could just
build one. So, the reason I wanted this info was so that I could build a
cross-adapter for the Yeasu and Kenwood mikes I have.

Thanks again Keith!
