Here are the Pin outs for different mics that will work with your radio. If a wire is not listed then you cut it off. It's best to keep the wires as short as possible no longer than a half inch is suggested. Normally the Cobra pin out is standard for most radios.

Hello,
Here is the wire diagram for several common mics in relation to a 4 pin CB. Most recent 4 pin CB's such as Midland, Cobra, Connex, Uniden, etc can use 4 pin mics. The wiring is actually depending on the mic rather than the CB so long as the CB's are 4 pin as well. Once you go back to late 80's the 4 pin design was a little different. Anything new it is simpler.

Pin-1,shield and black, Pin-2,white, Pin-3, red Pin-4,blue.

The wire colors are as follows
1.shield 2.white 3.red #4.black The pin numbers are located on the end of your mic plug


1.shield 2.audio 3.transmit 4.recieve

Use trial and error systemathically. If still refuses to work, mike and radio aren't compatibles.
