Help? Rain sensor? (Regen)

I glued the sensor behind the emergency switch and led the cables through a small hole in the interior... I hope this helps you ...
 
I can not find instructions to install the rain sensor to the top of the mower. Can anyone help? Thank you
This would have been the right sub: https://forum.ardumower.de/forums/regensensor.21944/

Anyways, so the installation on top is a little tricky. Everyone is doing a little bit their thing on how to properly do it so there isn't a bad or wrong way.
What you could do is get a little waterproof box and screw the sensor on the top and put the electronics inside the box.
