You have got a sharp eye for details.
I got confused for a moment too, until I took a closer look at the picture I posted above.
This is how it should look like, the slots are on same side as the one in the drawing, take note of the orientation of the letter "B"
This is the photo which I posted above with the slots on the wrong side, look at the orientation of letter "B", it's facing the other side.
Now, If I flip the same photo using photo editing software, the orientation of the "B" and the slots are correct again.
I think, someone from RS component has flipped the original photo of the connector when they put it on their website for unknown reason resulting a connector that never exist, confusing a bunch of Guzzi riding guys ;D
