Good point, Wolfman. I did try both clusters (my original and the eBay) in a friend's '04 Aveo and the tach worked. In both cars, the miles indicated changed to what was originally on the cluster (now 6925 miles), so if one was to install it, and was worried about 'turning the clock backward,' so to speak, he'd have to go to the dealer and have it flashed to the actual mileage.
