So I was driving my Miata after putting it back together and it was great... Except for the things mentioned in the title.

By electrical dash gauges I mean all the ones that are fed by an electric signal: The tach, the temp, and the dummy pressure gauge. Neither are the warning lights in the middle (CEL, handbrake, seatbelt, something).

The regular lights, running lights, brake lights, and those other things still work, is there a ground for only the things I mentioned? Perhaps 2 or a fuse or something?

Sorry if this doesn't belong at Miataturbo.net, I posted this over on M.net but no one notices those threads, they're all interested in posting in threads like:
I so seldom rev my car to high RPM's and when I wonder what I am missing out on - MX-5 Miata Forum

Any help would be greatly appreciated, I'm a noob when it comes to car electronics.
