One should be a ground. look at the board were the wire is.. and its obvious that its a ground pin 1. then should have 3 remaining. one will be tx.. touch the others to ground to see which one makes it tx.. theres your pin 3 tx.. on a galaxy pin 4 is not used. thats rx pin4 cobra radios would have a increase in rx audio when this is connected to grnd. the last would be audio. once you find grnd and tx. reconnect mic and put to pin 2 audio. the last 2 wires that gives it audio..
