HELP! Washer Fluid Reservoir

[egf265]

I’m putting in a new windshield washer reservoir and can’t figure out a part. I’m not even sure what it is for. The reservoir only has 2 holes for the back and front windshield sensors. The only number I can find on the part is Y05 11068.

did you order the correct bottle?..im asking this as there are 2 different units 1 with 2 holes 1 with 3 holes
3holes=front and rear wipers and level sensor
2 holes= front only and level sensor

I was wondering if that's what it might be, I of course threw out the old one and then came back months later to finally put the new one in. It still works without putting that piece in (must be the level sensor). Thank you!
