I'm replacing the pump on the reservoir and found this probe(?) hanging freely. Looks like it mounts somewhere? Anyone know what this is and where it mounts?
Probe mounts where?

 

It’s likely the washer fluid level sensor or a temperature sensor. If it came from the washer reservoir, check for a hole on the side where it should mount. If it’s a temperature sensor, look for a bracket near the reservoir or bumper area.
