I bought this instrument cluster to replace the original one I had in my 2005 STX. Mine didn't have a tach but this one did with silver highlighted background. Using Forscan and my laptop, I pulled the "as built" info from my original ic and transfered it to the new one to get all the lights and warnings to work. However, that was easy and now it functions just like the original. I am very happy with my new instrument cluster.
