I have a 2006 660, parked in covered garage and a rat made her nest under plastic housing between seats. She chewed 1 wire In half that wire is white with blue stripe (pic included). Also included pic of the threaded port where I guess the term “sender” was located and picture of “sender” included. 3 questions 1). Is this the water temp sender that goes to over heating “dummy light?” 2). Does the radiator fan turning on use this “sender” or wire in anyway to cut Cooling fan on? 3). If this is the correct location in picture Can someone post a link to a gauge that has an appropriate “sender” already attached to wiring and gauge so I can just screw it in and mount it. I have read many posts on here but Old pics Don’t seem to load. I understand there is an issue with threads not matching up and don’t over tighten. Thanks for your time
