This picture theoretically shows the installed harness for the A/P knobs. Without a careful map, I think you’ll agree with me that it looks like a rat’s nest. There’s only one more wiring harness that gets added to this mix, so this picture is probably your best bet for a view of maximum chaos.
You’ll also notice that the upper fuselage skin has been removed, despite my previous optimism that I could avoid this. I suddenly realized that there was simply no way I was going to be able to install all of the brackets & hardware into that space, even if I could get the harnesses back there. (BTW, in retrospect, I don’t believe I could have done that, either.) Taking off the upper skin was the pain that I expected. The bead of black gasket compound was extremely tenacious and challenging to disengage. I’m pleasantly amazed that I didn’t crease the upper skin while taking it off.
