The aviation connectors have solder lugs with the pin numbers labeled in the plastic molding. They are pretty tiny and have the numbers spaced confusingly (why are the numbers evenly/ambiguously spaced between the pins?!), so we've created these diagrams and photos to help.
The connectors are keyed with a notch at the top to aid in orientation, as well. This is important because the connectors can only be coupled one way.
