More Wingtip Wiring

I spent the rest of the time after finishing the rear baggage panel starting the wiring for the wing tip. I believe I am going to need some terminal rings but I need to see what size, etc. The grounds I believe need to be attached to the exterior of the light as there are two bolts there I believe I can remove and put the rings underneath. I will have three in total and there are two bolts. I need to double check that though but the wires have been terminated at least. I need to label them all and then stick them in the harness. I will then need to window splice in the rear nav lights into the correct wires and put some shrink wrap on that. I put some sheathing on the wires going to the rear lights so that it could be protected from any chaffing. I need to glue in some tip tie mounts so I can affix the wire so they aren’t flying around but I still have enough of a service loop to pull it out some if I need it.
