Where is the mileage data stored? Is it on the cluster? Thinking about changing out the cluster but would like to keep the mileage info. Also anyone know of a cluster that displays gas info as well?

 

On most I think it's in the cluster itself. To maintain the right mileage you need to send your used cluster and some other kinda proof I forget what, to a certified dealer who will send you your new cluster with the fixed mileage.
