Here is an 89 S10 Blazer cluster. Any idea if it would fit my 92 and would the tach work??

check the back of the cluster connections to make sure the color code pins are the same and that the cluster has ether the cable or not depending on the original one,i have an 87 s-10 and i change the cluster on it.had to do some changes on the pins they go by colors make sure they are in the right order.
