With the stock PCM located inside of the air filter box, many are left wondering what to do with it after purchasing an aftermarket intake. This PCM tray is a O.E. GM part and will look stock when installed. Simply snap the PCM into the tray and that's it.
Note: in order to use all of the trays mounting points 2 holes will need to be drilled on the fenderwell floor.
Most vehicles through 2005 use the large Series II PCM core. All 2004+ Grand Prix' and most 2006+ W Bodies have the smaller Series III PCM core. We do not offer a plate for the Series III smaller PCM. There is no tray for 1997 vehicles as they have a different PCM than all other years.
