If your mic has the curly cord, pass the ground wire through the coils. 
   It's really just a way to make it neater.  The important thing is to 
get a good connection at each end.    Some people run the ground wire to 
the back of the radio and connect to the ground lug.    This works fine, 
but if you want to disconnect the mic, you also have to undo the ground 
wire.

The other way is to connect the wire to the mic connector at the radio 
end.  Either under one of the 2 little screws, or between the  saddle 
clamp and the main  body of the connector.

One or two snap on ferrite beads on the mic cable probably wouldn't hurt 
as well.
