I used shrink tubing to finish off the end of the wires. Then I put braided sleve on the wires to route thru the fuselage holes. No nuts used on the connector. If the threaded holes strip I can add nuts later.
I added an adel clamp to hold the wires down out of the way of the push rod that will connect to the ailerons. I ran the left wires to the center and thru the hole and reserved the holes on the left for the pitot/static that will have to run in here.
I really would like more holes thru the center bulkhead, the wing box spar for wires and tubes. I'll look into this.
