Hi John and welcome to the forums. What you have found is the outside temperature probe (temperature displayed next to the radio display on the dash) So best not to push this again as you may end up breaking it.
I must admit that the first time I saw it on my car, I wondered what it was for.
Currently in dave_mezza2006's garage:
