Finish adding all of the signal wires to the ethernet module, and then also run power to it and the Arduino from the Buck converter. Here, RED is the Buck output, and BLACK is GND.

The mode switch also gets wired now, by soldering the bottom pin to the side of the RJ45 or to any other convenient GND point. The middle wire is connected (GREEN) to Arduino Pin-8.

I have added a bit more translucent electrical tape between the switch and the RJ45 jack after doing this, to prevent future accidental shorts there.
