My Cluster is completely dead

If the vehicle’s battery was not disconnected prior to removal of the cluster, it may blow inadvertently blow a fuse along with the wiring behind the dash, a relay near the fuse box, or a fuse in one of the multiple fuse boxes located throughout the vehicle. Often times there are communication issues that may prevail if the cluster is installed back in the vehicles. One of the fastest and easiest ways to clear any soft codes in the vehicle is to do a simple battery reset:
                - Disconnect the battery cables and have the unit installed in the vehicle
                - Clamp the cables together with the terminals touching (off the battery!)
                - Leave the cables maintained in this position for 30 minutes and then re-install 
    *This should clear any soft codes and communication issues with the vehicle’s PCI bus.*
