In theory... You will need to add the switches (99 up), change the clockspring and add the servo with it's vacuum line. I am in process of attempting this on my 98. Be advised that the switches are different. 96 down, 97 and 98, 99 up are the combinations. Leave it to Chryco to complicate it. The PCMs are the same inside of each year with the exception of the emission mapping. So you should not have to change the PCM.
