Standard mic wiring for cobra/galaxy/uniden 4 pin:

Pin 1) ground
Pin 2) audio
Pin 3) PTT (tx)
Pin 4) RX (sometimes not used on relay switched radios, and some galaxy/uniden radios, but good to put the RX wire there anyhow)

Hope this helps!

thank you so much for getting back to me exit but i need to know where all of those little components go, i dont know which wire is which. if anyone does please feel free to jump in .
take care Exit

Okay,

Upon further inspection, the black wire and white wire are in the correct places on the jack. the wire connected to the little choke goes to pin 3, which has the orange wire stub on it. Looks like the small ceramic disc capacitors (looks like there are 2 there?) are just clipped and can be reattached.



Hope this helps!
