The color of conductors are consistently assigned to a specific "pin" on a
microphone connector. I have seen identical microphones very, due to
different cable sub-contract suppliers.

And of course, the connections to the RJ45 are different across Icom radios,
too. Hopefully, the manual for *your* SM-8 should show what color has what
function. You need to mate that with the manual for your radio.
