This may be a dumb question, but I haven't stumbled across the 'ground block' yet. I would think that somewhere under the dash there's a place where the grounds are accumulating, but I haven't noticed it yet. I'm sure that I just need to start tracing the ground wires off the gauges or the switches...

At least the fuse block is obvious. Is that powered by a run from the starter relay terminal?
