That insulating piece on the terminals had a vertical section on the originals. That helps prevent the gauge from going "poof" if someone messes around while the wires are hot, or even just a random short between the terminals. Here''s a photo of that insulator. It would be pretty easy to fabricate a replacement from some card stock (gasket material?) Of course, the terminals need to be insulated from the cluster housing as well. It won't work very well if they're shorted together thru the cluster. Reminds me that I should go check mine before I install it.
