You mean K144XV, if it is internal, and for the K3.
The circuit diagram is on the last two pages of
<https://ftp.elecraft.com/K3/Manuals%20Downloads/K3_Schematics_Jun_2010.pdf>,
but the programming connector seems to be a six pin header, not a jack.

Elecrafters,
i purchased a used internal K3 2m Transverter. I would like to check and
update the firmware.
For this, i need the pinout for the 3 pin stereo plug. I have real rs232
interfaces on my computer and will make a cable on my own. I suspect i
will need pins 2 , 3 and 5 from the D-sub 9 connector, but don't know
where they will go on the 3 pin stereo plug.
