Jason, So many questions so little time lol.

Lets start with the ammeter: If youre at Negative Ground, the + Supply side needs a hot battery feed, and thats often taken from the post on the starter switch as it has a big cable leading direct to the hot + ungrounded battery post or it could be taken direct from the battery + post itself, I would use 12 Gauge red wire there. The ammeters + post only has one wire there.

Ammeters - Load Terminal: It has two wires, one down to the BAT terminal on a 3 or 4 terminal Voltage Regulator (often mounted to Generator) or the BAT terminal if it has a 2 wire cutout relay. (Use 12 Gauge red) The other feeds loads like lights and ignition via a switch, so it wires to the BAT input terminal on the switch and I would use 12 gauge.

Switch: It receives its input voltage from wiring its BAT terminal to the ammeters - load terminal (see above). Its IGNITION terminal is what feeds voltage to the + coil when switched to ON. The coils other - terminal wires to the distributor.

if youre at Positive Ground, the ammeter leads are reversed from above, i.e. - to battery/starter and + is the load side to BAT on switch and BAT on a Voltage Regulaotr or cutout relay. Also if at Pos ground, the coil leads are opposite from above, i.e. - gets power form switch and + wires to distributor.
