katrinaxr6turbo

Hi, Can someone please help me. We have just put in a second hand ICC unit into my car as the old one was busted. When we have plugged it in, it comes up saying we need a code. I know this is generally specific to the car but does anyone know where I can find this info? Have looked through all the books and found nothing. Is it easier to take it to Ford and have them decode it? Thanks
