Mirror Wiretap Question

[mitchell allard]

About to do a mirror tap to hardwire radar detector to mirror.
Does anyone know which wires on mirror harness are ground and 12volt switch?
Don't have voltmeter. If no one knows I can get one.

You're welcome. I was just reading a thread on a different forum about the same subject and someone posted this pic along with his install.

That looks like the way mine worked out, too. One thing - when you put it in reverse the power cuts out.
