You can do a 88-89 cluster to a 90-91 but i've never done it befroe....probaly takes a **** load of wiring and ****...not to metion that the clusters are very different....
ITs one harness screwed into the back of the dash. If you find a 90-91 dash that has it just unscrew the warness and remove the plastic fasteners. They are almost exacatly the same but 90-91 has a wire that plugs into the rear middle section of the 90-91 cluster. The 88-89 does not have 3 plugs on the back Just two.
The 90 91 dash you have is useless to you for what you are trying to.
