Bill, the following should help.

Front panel view of 8 pin chassis mic connector.

Indent located at 12o'clock position, working anti-clockwise.

Pin 1=Mic input
Pin 2=+8v @10mA dc output
Pin 3=Freq up/down (Ground direct for up, or via 470 ohm)
Pin 4=Squelch switch (open=low,closed=high)
Pin 5=PTT
Pin 6=Gnd (PTT)
Pin 7=Gnd (Mic ground)
Pin 8=AF output (Middle pin)

Icom warning, do not short Pin2 to gnd. Damage to 8v regulator will occur.

Taken from Icom manual
good luck, Roger G7JAQ

PS, for MIKE read MIC
