is yours auto or stick? I think the auto you MIGHT have an issue but I dunno... stick should be ok. But you never know there are a lot of wires running behind the cluster and no connection might piss something off.
kinda off the subject, but on the S-10's in auto, if the evap plug is not connected (red one that goes into the little module that connects to the canister), the vehicle will not drive. you can shift into D or R but it won't go anywhere.
