I think they were black and brown, but once you open mirror cover there are only three wires that go to LED. I used 9V battery to find which one -- it was easy.

I am not sure where LED wires go by default since I did not spend any time tracing them. But based on Ohm/Volt-meter readings it does not look like they are connected to anything until factory alarm is installed.

I used bolt next to a sunroof motor for ground wire.

Yes, that is pretty much it.
