Equipment / Re: CB and JS8Call setup help

That is pretty much what I'm looking for. Unfortunately, I'm one of those very slow individuals who needs things explained like I'm 5 years old...
I did find a 4 pin TRRS adapter cable that should work for this, and is set up like this:
Pin 1: "L"
Pin 2: "R"
Pin 3: "V"
Pin 4: "Ground"
Using the Cobra/Uniden schematic you detailed, what would I hook up to where on this adapter cable for purposes of mimicking the "Transmit" function? My guess would be "Cobra Pin 3" to "Adapter Pin 3", and "Cobra Pin 1" to "Adapter Pin 4"?

If I'm understanding the USB sound card correctly, the "RX" radio function feeds to the headphone jack on the sound card; The "TX" radio function feeds to the mic jack on the sound card. The "RX" output should be handled via the CB's external speaker jack. The "TX" output is where I'm uncertain.

If I'm understand you correct - maybe try the following:
The 4 pin Cobra/Uniden Mike connector is
Pin 1 - Massa/Ground
Pin 2 - Audio
Pin 3 - TX
Pin 4 - RX
Just shortcircuit pin 1 and 4 for RX
From Audio source/speaker/Soundcard
Wire audio plus to pin 2 and audio min to pin 1
