Lightbulb OTG Issues

I have a 1989 260E and have a problem with the OTG (outside temp gauge). The display reads 123 degrees all the time. It worked when I bought the car in 1998 but went haywire shortly after. I traced the sensor (from under the licence plate) and it appears to go into the fuse box unless I got my lines mixed. Does anyone have any diagnostic / replacement tips and or where to get a replacement sensor assuming that's the problem.. Here in Vermont an outside sensor comes in handy on those -20 winter days
