Spent a lot of time in the garage on a variety of wing close out items, mostly wiring related. I had previously used 5/8” snap bushings for all of the holes in the ribs for wiring. That was a good size for the max number of wires, but outboard of the roll servo t the wires were pretty loose in the bushings. I elected to pull all the wires out of the wing and install tighter bushings where appropriate. Happier with it now.

Other motive for pulling the harness was I wanted to replace the ground wire for the AP servo. It was a little shorter than the other wires and preventing me from adding the service loop I want to have at the wing root. Could have spliced a little more wire on, but why have a wire splice on a brand new wiring install? Took apart the Garmin connector and switched out the wire.

I noticed as I was removing the harness that many of the original ties I had done are not holding up well. I had some Gen 1 lacing ties that were garbage that I had already removed and redone. These were Gen 2 and still aren't holding up well either. The Gen 3 ties seem to be ok. I'll re-tie everything in the wing and probably get rid of my group ties, just tie the big bundle.
Then worked on the molex connectors at the tips. Got the connectors done and wiring tidied up. Looks good. Going to just keep working from the tip toward the root finalizing all the wiring as I go.

9/19: got the right wing wire bundles all tied. Cleaned up the AP servo loop and the branch for the trim servo. Still need to add the connectors for the trim.
