I popped out the dome light and found the harness for the electrochromatic mirror (blue plug, wrapped up in tape tucked into roof)
Then I used the included wire splice and spliced the V1 power wire (red) to the yellow wire on the blue plug. I took out one of the screws that goes into the roof, and put the ground terminal thing on there, and put the screw back on. I then proceded to stuff all of the excess wires and the phone jack thing into the roof liner. Then I snapped the dome light back in, and it's worked PERFECTLY ever since!
Thanks for the info.
