Cluster won't work??? HELP
 

I purchased a cluster off of another LS1Tech member 99Z28camaroman , cause they had white faces, and blue bulbs. After getting it, I removed my working cluster and installed the one I purchased, and alot of the gauges on the new one will not work??? The speedo, tach, mileage will not work, the battery, oil, temp, gas do work??? I can put my original cluster back in and it will work fine??? I'm stumped!!! What can I do??? Reset the computer??? Take to the dealer??? My car is a 2002 Z, and he said the cluster came out of his 1999 Z.

if you can put the original cluster in and it works fine and you follow the same steps when putting the other one in..........that aftermarket cluster is the problem
