No, you cannot directly swap a 1994 Tahoe or Suburban dashboard into a 1992 Silverado. While they share some GM lineage and might look superficially similar, there are significant differences in the instrument cluster, HVAC controls, wiring harnesses, and mounting points that make a direct swap impossible. The body styles and interior structures are different enough to create incompatibility.
You might be able to adapt *some* components, such as individual gauges or switches, with significant modification and custom fabrication, but a complete dashboard swap is not feasible without extensive custom work.
