I spent the whole day paying ignorance tax (aka stupid tax). How did I think those wires were going to get in there?
Here's my solution. Drill access holes inside the footprint of the light's base and spend the day trying to get the nuts and washers on the screws inside the tiny and shallow wing tip.
For the aft hole, I taped the washer and nut together and then taped them to a piece of thick sandpaper. Once inside the wing, I used a magnet to hold it against the skin while I slipped in a finger to hold it in place while I screwed it in. Once started, I inserted a small wrench to hold the locknut until it was tight. That was the hardest nut to get on.
