Ok, Im driving a 2003 Monte Carlo SS with a top swap (supercharged) I would like to know if I can switch the guage cluster from a 2004 Monte with the boost guage into my 2003, and what modifications, if any, need to be made... Anyone do it?

 

seriously good question! I have the S/C gauge cluster, and wanted a voltmeter, so I added a center console dual gauge cluster . The 2nd is trans' temp

Does anyone know the answer to this?

I'm going to guessyou need a PCM and maybe even a BCM from an '04 to get this to work. I can't say where the boost sensor is, but I'm guessing the wiring from the PCM to the cluster is identical N/A or S/C. The clusters are all electronic. Programming is different. ??????
