git looks to have a 10 wire harness.
i took it apart and noticed that the 4 buttons on the front panel had a handy 5 pin header and socket. (4 buttons, 1 common ground)
this leads me to believe that the button presses are not serial and and the connect directly to digital inputs on the master module. that would leave 6 wires on that harness for the display. two of which are power and ground. that would lead me to believe that it's a serial lcd?
(edit: i contacted the person who made that and the buttons do extend out from that wire harness.)
The one thing that i'm still trying to research is how to reverse engineer something using the logic analyzer. I'm very new to this and admittedly confused at how to interpret the output from the L.A. into something that i can work with
