That's also news to me (going to the dealer to program the new gauge cluster)!Soup,
This is the first I heard that the cluster needs to be matched with the car. Everything I have read up to now indicates that the clusters are just a simple display driven by the BCM and are interchangable.
Since I am planning on doing this with both my cars - custom Black Cat plus bright LEDs - I would like to confirm that I need a trip to the dealer when I do the swap.
I bought an extra KPH cluster and switch with a new face cover and works fine in MPH....
