I have been chasing / repairing many vacuum lines on my car an found this switch between the expansion tank and the battery. It’s actually attached to the expansion tank bracket. Unfortunately it’s not connected to anything so I have no idea what it’s function is and how and where it should be connected. I would appreciate if someone could point me in the right direction. Thanks
