I have a Turner 454X microphone that I would like to wire up to a standard Cobra 4 pin configuration. I am having a hard time determining what the color code meanings are for the White, Red, and Black. The ground I think is obvious as the ground / shielding and it is wrapped around the white. Could someone enlighten me?
Cobra:
1 = Shield - Com
2 = Audio
3 = TX
4 = RX

Turner:
Braided = Shield - Com
White = ? Audio Lead ?
Red = ? TX ?
Black = ? RX ?

It goes like this. White and shield are the microphone connection and the red and black are the keyswitch.

Thanks for the reply. So, I have it backwards as red and black but, how do I know for sure which is TX and which is RX?

I did some digging around and the Turner wiring booklet says RED - receive switching and BLACK - transmit switching for electronic code (E) for switched from receive and transmit by means of vacuum tube or solid state circuitry. Matching it to a popular model like the 29 then shows:
Pin 1 = Ground Shield
Pin 2 = Audio White
Pin 3 = TX Black
Pin 4 = RX Red

Does all this sound kosher? I don't want to short anything out be inadvertently reversing something.
