1. Made some cleanups and clarifications to my wiring diagrams. Researched exactly how power is to be provided to the GTN 650, and made sure the wires I'm about to run are properly sized and protected. (The GTN 650 has by the most stringent power requirements of any avionics box in my plane, with seven (7) separate power inputs across three connectors.)

2. Planned the wire routing for the magneto leads, which will pass through their own separate hole in the firewall, and will be routed just underneath the forward baggage compartment on the far left side.

3. Laid out some the major electrical components that will be mounted on the front of the firewall, and decided to mount them together on a custom 5"x9" standoff plate, using Z-channel as a support. I don't have enough spare 0.050" aluminum sheet to make it yet. So for now, I'm going to mock it up with poster-board. (The only items that will not be on this plate are the two shunts.). Each of the items will be fastened with nutplates so they can be easily changed out if needed at a future date.
