Puxing Microphone Cable Wiring

I bought some Puxing hand-held radios for use on Packet Radio. I made sure that the radios purchased had external headsets. To use these, I had to figure out which wires where which. This was very simple, but I document it here because I couldn’t find it on the net elsewhere.
