If anyone is interested you can get your Ninja 250r OEM connectors from the below website.

Blinker light is the
2 position 050-HB Connector
(this has been corrected, used to say "HC" prior to update)
License plate light is the 2 Position .110 Connector
I think the tail light is the 3 Position .110 Connector (but haven’t tried it yet).
I am in the process of installing the Bike Monkey integrated tail light and Speed Tactics fender kit. One of my goals was to make any mods completely reversible and that means not cutting ANY wires. Installed the integrated tail light and it was all plug in and go.
Service was quick. I’m in NZ and they arrived in 1 week.
