Wire/tube bundling and subpanel wrap-up

I bundled all the side wires to the panel:

Side wires bundled up next to panel

We also connected the remaining wires to the alternator regulators, and regretted again installing them behind the subpanel due to the gymnastics required to do this:

I also finished installing and torquing the engine grounding straps:

I tested the LED strip position to see if I'd need to cut it to reduce glare (apparently not), and ran the wire through the panel with the tiniest snap bushing I could find, which turned out to be 0.19" OD. The wires will be hidden between the metal and carbon fiber parts of the panel:

The Mountain High O2 system has an emergency O2 valve - the valve itself is in the regulator (attached to the tank), but it's pneumatically actuated (supposedly so it works even in a total electrical failure?), so I had to run the tubes for the emergency O2 switch into the panel:

In case you're wondering if I'm fully done with avionics - of course not :) the wiring never ends...

Time lapse:


Total avionics rivets: 181
Total avionics time: 425.6h
