Cluster ground wire ?
NONONO!!! LOL. The ammeter is NOT grounded!!! That great big huge gigantic black wire on the ammeter runs to the alternator.
What you need is simply look at the cluster. Look at stuff like the illumination lamps, and the board traces. These are all connected together. One trace is the ground side, and works around at some point to mounting screws on the cluster. Any one of those is a ground point and you can use one of the screws.
Since there are several cluster designs this is difficult to show. This is out of a Dart, the black arrows are the mounting/ grounding screws. Any one of them will work for a ground point. Not all cluster housings are metal but these are still the ground for the lighting and cluster.
