Got everything sorted out and organized back on the board. It turned into a real mess at some points but it all came together really nicely. I'm glad I took the extra time. I'm certain that there will be an extra wire or two to add but I'll deal with that when it happens. For now it looks perfect.

Took a while to figure out a system. Worked on a couple of the major branches back towards the middle and then once I got the middle segment sorted, the rest fell into place. Just time consuming. I bought a bag of 1000 zip ties and went through half of it temporarily tiring wires in small bundles and then bigger bundles and cutting the original ties.

Everything is zip tied for now. I'll use lacing chord when I finalize it with the connectors. Right now I just want it secure so I can put it to the side for a while and get back to finishing the forward fuselage.

5/1: test fit the harness back in the subpanel and realized I had one of the branches off a bit. Put it back on the board, upside down this time to allow easy access to the data wires. Was able to fix the routing and get a few more twists out of the data wires so they now lay as flat and smooth as the power wires. Put it back in the subpanel and confirmed the fit. Looks good.
