Default 98 PCM questions

Can a new VIn number be flashed into a 98 PCM or do I need to change the PCm and harness to a 99-00 style for a new 01-02 VIN to be flashed into it?

Im trying to get away from the lack of tuning tables for idleing provisions in the 98 cars.

You cannot flash another year OS into a 98 computer.

OK..Will the 98 harness still bolt up to the newer shaped PCM's. Id think that they will, but id need to repin the harness since some of the wires are in different locations. Im on the right track here? yes or no?

not some of the wires, MOST 95+% of them need to be moved or more.

Some of the dash harness has to be redone, and the gauge cluster too.
