The problem is not finding the right connectors, but more figuring out if I'm
going to drill in my wingtip etc.

I am lucky enough to get Lemo or Souriau connectors with the appropriate tools.
These are mil-specced connectors, so have all the features I need (pulling the
wire will only tension the mantle, good locking mechanism, etc).

For example: how to connect a chassis-type Souriau connector to the wingtip? The
chassis-connector has 2 holes. Should I screw them to the wingtip with screws that
require no drilling? Or use blind rivets?
