When you get the microphone.  Remove the strain relief connector by removing the two screws and then remove the very small phillips head screw in the side of the connector and twist the shell a 1/4 turn conterclockwise and slip the shell back on the cable.  You will find that Pin 1 has a yellow wire and it is the mic audio and connects to Pin 1 of the new 8 pin connector.  Pin2 has the shield connected to it and is ground.  It connects to pin 8 on the new connector.  Pin 3 has a black wire  and it is the PTT line - It connects to Pin 2 on the new connector.  Pin 4 has a red wire and it is the 5 volts to the elecret element and it connects to Pin 6 in the new connector.

You will need to place jumpers on at least the four lines 1to 1; 8to8; 6to6 & 2to2.  These jumpers are on the connector on the back of the Front Panel Circuit board  P1  Mic Config. Connector  You can use the standard computer jumper plugs.
