Thanks, I've tried searching some threads and couldn't find much. One thread the installer already had the proper wire from the previous owner. I'm wondering if I can just use the constant supply wire from the cell phone adaptor?

Would appreciate it if you knew which thread, I tried searching 12v constant, metra radio, etc.
