Ok I got a auto dim mirror out of a mark 8 to install in my 87 bird today. As I was getting ready to start wiring I found a 4 wire plug tucked under the head liner by the mirror. Anyone know what it is for. The car has a regular flip mirror in it when I got it. Any one know what it is for that would be great.

Did the birds of this year range come with headlamp dimmers? Could that be the plug in for the sensor that turns your highbeams off if it see oncoming head lights?
It certainly looks like the auto dim wire harness to me
Yea It has to be something for the auto dim it only has live power when the head lights are on so I wired my mirror to it.
