Hey guys I have a 99 f150 and my cluster is screwed up I went to the junk yard and pulled one from a expedition 99 as well.. went and put it in and not start theft light flashing and so I swopped it and continued using my old one.. how can I use the new cluster any help please!!!!

 

The new cluster has to be programmed into the PATS system, usually by the dealer or a well-equipped locksmith or mechanic.

You cannon simply slap in a replacement cluster for any F150 starting in 1999 model year.
