As far as I know, this is supposed to be a rear view mirror selector switch from a Ford, at least that's what I was told by the guy who supplied it. He doesn't even remember it now. It's currently being used as a turn signal switch in a car I'm re-wiring. The mounting tab as well as the plug anchor tabs are broken off. The anchor tabs aren't an issue but the mounting tab is. I need to know what the application is so I can go to the dealer and get a replacement. Can anyone identify the application? Lincoln? Ford F350? Taurus? what is it used on? The only markings left are "INDAK" and "PAT. PEND."
