COntrol Check display failed. Cap replacement no good. Found used instrument cluster (>2/89) to replace my original (8/88). Now odometer coding plug is built into cluster vs connector. Has anyone purchased a separate odometer coding plug? How can I get the mileage back to the original (114K) vs the mileage in the od coding plug (208K) in cluster bought used. Other than that, the "new" (used) cluster works great!!
