I started out the night sanding down the filler I added to the plenum and adding a bit more to fill in a couple of low spot. Next, I decided to take care of a bunch of odds and ends on the plane. I added some adel clamps to hold the alt air and oil cooler control cables to the subpanel.
I also zip-tied them together in a few spots which really stiffens them up.
I also cleaned up and secured all of the wiring bundles in the forward part of the cabin. With that done, I think I’ve wrapped up virtually everything behind the panel and subpanel.
