The perhaps default open-source radio programming software distribution CHIRP does not at this time support this radio model. Maybe, if I'm successful in my work, that can be changed.
First things first. To decode the data, I need to get the data. To get the data I need to listen on the communication wires, so a junction box was built. Given that I'm building with what I find in my parts bins, rather than routing a proper board and ordering parts, the final result does perhaps look more grown than designed. ...And that's not really false marketing.

Also, I want to keep my options open.
Since the radio is programmed with 5V signals, and the snooping ports work at RS232 levels, a level converter is needed. Again, lots of switches for connectivity options, and mixing SMT and through-hole devices oh my.
