Programming / Calibration of 03 Sierra Cluster

Question

Hi guys, just finished adding the seventh motor (Trans Temp) on my 03 Sierra 1500 cluster. When I turn the truck on, the needle doesn't move during the self test. Read that if it is dead, my cluster (which I suspect isn't the original) doesn't have the necessary programming. My friend who owns a fairly large repair shop, has the Tech 2. So my questions are, what needs to programmed? Can I do it with the Tech 2? If I can do it with the Tech 2, how do I go about doing it?

 

Thanks for any help
