I did mine today in my 08 and I used the yellow wire from the compass mirror and a white/black stripe(ground) from the overhead console where the lights, homelink, and sunroof is. I tried a power wire from that same harness and it turned out it was for the tilt up part of the sunroof. So when I turned on the V1 it tilted up the sunroof! HAHA So I moved it to the rearview mirror yellow wire.
