A nice addition to the wing wiring is studs and plugs at the joiners. You often see professionally built machines built with built-in connectors at the panel joins. I found a way to accomplish that.
At Gateway Electronics, I found the male pins and the three port female connectors. I first started at the outboard panel with the male studs set in a piece of circuit board that would fit nicely into the factory cut hole. Solder and heat shrink outboard wiring to the inside studs of the male terminal. Ran the wire through the factory created hole to the aileron servo. I used 5-minute epoxy, adding a drop to the outer edges of the circuit board.
I used the male studs to maneuver the assembly through the wing hole and set the plug in place, flush with the inside edge of the rib. Let this dry overnight making sure it is solidly attached. Assemble the female connector with wire then slide the male and female connectors together. It should be a nice tight fit.
Ran the wire off the female side down through the factory provide hole. Joined the inboard and outboard panels while sliding the female connector into the hole in the inboard panel. Slid the two panels until they are about a ½ inch apart. You need just enough room to glue the edge of the female terminal. Do not use so much glue that you end up gluing your two panels together.
Clean up any excess glue, insert a single edge razor blade and slide the two panels the rest of the way together. The razor blade will keep the two panels slightly apart while the epoxy hardens. Once set pop the two panels apart and finish gluing the terminals in place filing any open space with balsa to give it a “purty” look. Warning: the female connectors are subject to getting glue inside on the brass connectors; make sure you don’t let any glue get on this brass it will cause you to have electrical problems.
