Hello all. I have a 2006 chevy silverado with a Z1 installed in it. When i had the stock radio installed and i shut the truck off the radio would stay on until i opened the door. does anyone know what wire i need to hook up to make my Z1 do that? right now it will turn off as soon as i turn the key off. thanks for the help.
