Actually the startup doesn't match exactly. The numbers and needles light up on the guages for start up whereas the STi cluster only the needles light up for the the startup. I was a little disappointed in that... but once they are started up they match PERFECT. Having the cluster and guages both made by Defi probably didn't hurt in that. And yes, my car is a mess. I planned on cleaning it inside and out when it was in the shop, but the install took longer than I had thought, mostly due to the fact that I was paranoid about screwing something up.
