Alternative to Molex Connectors
If I was starting over, I would replace all of the Molex connector with Deutsch style connectors. Particularly good for areas that could be exposed to moisture such as the wing root. These connectors are relatively inexpensive, will carry higher currents and are sealed from moisture. Sources are easy to find with an internet search. Come to think of it, the only place that I have not changed are the bulkhead connectors on my 14A.
