Hello!!
If a recall correctly you need one 9Pin Connector and one 2Pin Conector. Don't remember if male or female connectors but they are cheap so maybe you could buy both of them.
Here is the link

And a picture of the connector in my bike. I used a cutted harness because the connectors were lost in the mail. By this picture it looks like the connectors were MALE.
Also a picture of the speed sensor mounted in the wheel.
My RX2 had 2 temp sensors and one speed sensor... so with the mounting plate it was all done... I recommend using carbon fiber for the plate. Acrylic didn't last
Sorry I don't have more pictures of the process
Hope this helps
