2007 x5 Radiator Hose Question

[CLS70]

Hi
I'm replacing one of the coolant hoses (part 17-127-537-108); checked in RealOEM and bought the part.
When replacing, the hose that is currently in the car is different (WTH?), as it has an electrical connector
I double checked with my VIN and still get the same part number

The one ordered as per part number:



The one that is on the car looks like the frontmost one on this picture (seems someone had this same issue....) - note the parts numbers are the same (?????)



Has someone encounter this before? I can't find a new (or old) part number that matches the hose I have.....so if I use the new one, where does the electrical connector goes now????

Thanks
