Wiring more of the panel switches.

Another session of wiring the switches.

More switches wired

To add backlight to all the switches, I added the first fuse to the fuse block!

It's the wrong ampacity (15A), but I put it in just as a temporary fuse to see the lights working.

All backlight LEDs are working! There is one switch missing -- it was faulty, and I'm waiting for the replacement.

The backlight LEDs are all wired

I also installed the avionics diodes.

The shared avionics bus diodes

To test that the diodes can handle EFII system loads, I connected 6 H7 bulbs to the engine bus. The 6 bulbs should draw ~27A of total current (though I don't have an ammeter to verify that).
