OK, I think I got it now. However, if your drawing is good, I wired the fuse block incorrectly. I did it according to the directions, though. But, I guess all I need to do is wire the ammeter between the bulkhead and the fuseblock to make the ammeter work?

Also, can you advise which wire powers the gauges? This is for a rallye dash, btw. The fuse block has a terminal for powering the gauges, and I am considering using it. I have looked for a rallye dash wiring diagram, but haven't found one as of yet.
