Seems to be a cluster of cluster problems lately.
The pink/white wire powers the check engine light when tripped by the ECU. It plugs onto a spade connector below the clock.
The main power to the cluster comes from the red/black wire in the three wire speedo edge connector. That red/black wire is hot when the key is in the ON - KPII - position, and powers up the warning lights in that key position. You can test for power there with a test light.
If you're not getting the warning light test before starting, and the speedo is not working, make sure that the edge connector is seated properly.
