The TRRS breakout board came with some header pins, which I pushed through layer "[2](1)" and soldered in place. I pulled off the plastic molding that held them together and trimmed the tops to fit in my frame. I attached 30AWG silicone-coated wires to the sides and ran them through the wireway. I also wired the voltage display and addressable LED bar, which I forgot on the schematic.
TRRS headphone wires

The protoboard with the microcontroller and IO expanders got some wires on the bottom, which would be hidden once I installed the mounting screws. The conductors were color-coded with red as Vcc, black as ground, and blue and yellow for signals. I avoided populating any hole that might be necessary for connecting the keyswitches.
Protoboard wiring

I made the wires from the headphone module and LEDs long enough to reach while the keyboard was open so I would not have to solder them at an awkward angle. I kept the wires on the keyswitches short and tidy. In the layout, I planned to use all the connections from the IO expanders and one from the Arduino, but I crossed those out to connect the rows to the microcontroller and the columns to the IO chips, which meant there were spares everywhere in case something goes wrong.
