The connectors on this bike (and most Japanese vehicles in general) are from various manufacturers. Beyond that, each manufacturer has various lines of connectors that they sell, and the next variable is the pin count. Not all connectors are locking, and not all connectors are waterproof either although again, the Japanese vehicle industry tends to use both although they do use a fair amount of bullet connectors which are neither locking nor weather- tight.
So if you wanted a connector to handle 3 circuits, none to exceed 4 amps, the terminals and connectors to accept 18 ga. wire (with a given thickness sheating over the wire), then Brand Y, family F, connector 1-2-3 in four- pin might be the best choice. The next place you want to use a connector will have different requirements that a different connector, very possibly from a different manufacturer, may serve better.
And even when you choose a connector, there is often the choice of, say, a 4 X 2 matrix to make an eight pin connector, or 8 in- line. And none of the terminals (the metal tabs inside the connector bodies) are the same either but are unique to each family of connector (not even the same across a manufacturer's line of connectors). Why the whole thing is a mess I tells' ya'. Sorta' like lumber; all different kinds, sizes, treatments, colors, wood species and so forth. It is up to the user to pick and choose the best specific type for a given task. But watch out 'cause often times it is engineers who spec. them and as we all know, that is a low- down, stupid, graceless and evil group of people.
The great thing about connector standards is that there are so very many of them :-)

Was just thinking about this removing the left upper panel on my 2010 this weekend. All 3 connectors have different locking mechanisms. Was wondering why they couldn't standardize have have every connector lock and release the same way.
