If I were to pull a cluster from an Escalade at a junkyard, what would I have to do to make it work?
I have an '05 Tahoe 4.8L
make sure it is an 03+ Esky cluster.
easy way to tell is where the fuel gauge is (upper row or lower). that has to match yours.
then just plug it in.
Done. mileage is stored in the cluster, so you may want it reprogrammed.
Alternately, transfer all the esky part's to your cluster...
I wouldn't bet on a 4.8 being pre-programmed for trans temp gauge motor though, so reprogramming the Esky's miles is probably the way to go.
