Instrument Cluster Removal, Help!

First make SURE you have the battery unhooked. The ammeter connections are "right there" easy to short, and no fuse, 'cept for the fuse link

You already have the speedo cable off, ?? ALL ?? the screws out, and the column dropped down.

It just might be that the wiring harness in your particular car has not much slack. Be careful, there are two connectors on the PC board for the harness to the cluster.

You fold it "down" before pulling it out very much, it's sort of L shaped, and the speedo hangs down below the bottom edge of the dash opening.
