Can a used cluster from a bone-yard be reprogramed/recoded to show the correct mileage of my car. I am guessing if you just install the "bone-yard" cluster without recoding, it should logically just show the mileage of the donor car. However, I read another thread though the search here that it may display "True Milage Unknown" on the cluster unless it is properly reprogramed. Is it true?
