Not Ranked
I'd recommend running the ground wires to a stud behind the dash somewhere, not on the gauge. The setup you're talking about will work, but I wouldn't want all that current on the back of the gauge looking for a ground if your #12 failed for some reason. I don't know what your dash material is. If it's aluminum, then there shouldn't be a problem even then.
I have to respectfully disagree, in personal preference only, to wiring the grounds all together, inseperably (if indeed, I understood Karl correctly). I very much like to be able to replace wires one at a time, and want failure modes to be independant. Of course, I have been worked with a lot of vintage Lucas, and this might have made me unreasonably paranoid!
I also like to add a couple of cigarette lighter sockets up under the dash out of sight. Wal-Mart sells them, and they come in very handy at times.
