Dealers are not set up to reprogram clusters, and the factory will not reprogram a cluster that is anything different than the exact one that came with the vehicle.
You may run into issues when switching clusters, as the later you get in WK model years the more features and options that are integrated into the cluster programming and wiring.
2005-2007 clusters use three connectors (16+20+20 pin). 2008-2010 clusters use two connectors (20+20 pin).
Every single model year WK has different pinout assignments for the clusters.

What model/model year WK do you have and what model/model year cluster did you install?
