ALLways start with ground. Find ground on radio pin with ohm meter. EVERY thing operates off ground. Once you find ground on radio....solder your ground wire on mike cord to corresponding # on mike jack. Once you have ground on proper pin then all else is elementary......use ohm meter to see which wires are TX and RX on mike.....last wire is audio wire.

If you bought the mic new it came with a sheet telling what wires do what, most of those are six wire mics.
In your radio: 1=shield, 2=audio,3=transmit, 4=receive.
On most astatic mics shield is braided shield wire, audio is white, transmit is red and blue is receive.
The other two wires should be yellow and black, the yellow will not be needed and you may have to connect the black to either pin one or pin 4.
Best way to do this is wire the shield and receive first and connect mic, if you have receive, then go for the audio and transmit.
There are a couple of versions of this radio so you may have to experiment to get it right, Keep the solder connections neat and the wire short.
Let me know with a comment here if you have questions.
