Gauges on a 89-91 GA
 

On an 89-91 Grand am there was a standard gauge cluster and the optional cluster: which came with the tach, volts, and oil pressure gauge. I was wondering if I have a 2.5 engine with the regular gauges, will the optional cluster work? I'm guessing the gauges with the tach will physically plug into the dash but is the car wired for the extra guages?
