there appears to be a wire missing to connect into back of radio, its the small middle connector, if any thing goes in there? i assume its the right radio for the car as its the same that was in a previous 2001 mondeo? with regards the key, the locksmith needs a key code to cut off, as the 1 i have is very very very worn, so unable to take a copy of that! i need to know how to be able to read a code? would it mean diassmbling a lock on the car? would there b numbers on there?
