Well my truck is a 2 line display. I got the buttons for the center console and it was pre-wired for them so they plugged right in. I installed the 4 line cluster and several things happened. First it showed the milage of the original vehicle. Then my truck would not start and the security light was flashing rapidly. The buttons did work though. I am guessing that there is some PATS stuff in the cluster. I am guessing that a reprogram would be in order so it shows the correct milage if I could get it to work.
