I labeled the wires by writing on white shrink wrap and then shrinking it onto the wire.
The AC book says to respray primer on the grounding nut to help avoid corrosion so I did with it in place. This shouldn't affect the bonding surfaces.
Landing light is done. Except I've gotta decide what I'm going to do at wing root and how the wires will enter the fuselage. I will go look at website construction logs and Vans Airforce Forum to see what ideas I can find.
