Grey Tank Sensor Placement

[GoneWithTheWind]

Sensor has fallen off my Grey Water Tank. Can anyone? Let me know , where the mid level Tank should be attached to Grey Water Tank?
Thank you

I've attached 3 pictures of the location on my 2017 C/S.
It has fallen off frequently in the last few months, I have just reached up in between the Grey and Black tank as far as my fingers would go and pressed it back onto the side of the tank. I need to buy double sided tape and reattach it for a more permanent fix. If you look closely to the left of the white connector you can see a bit of blue painters tape that is currently holding it on. I have been placing it here each time it has fallen off and once it recalibrates itself it has shown the proper level on both the Sea-Level Monitor in the wet bay and the V/T inside the Coach.
