PCM Swap
Need a pcm for a 99 cherokee sport.
If I get one from a junkyard it comes with a 3 year warranty. But can I just take old one out and put the other one out.I keeo seeing it needs programmed for the vin number? Just trying to make sure I do this right.

As far as I know programming is not needed but the numbers need to match with exception of the last digit. Do a search here just to be sure about exactly which digits need to match. At the minimum the replacement PCM must come from a an XJ with the same exact options and CA vs. non-CA emissions. What make you think you need to replace the PCM? They tend to last the life of the truck.
