Connect BOTH wires that are currently going to your ammeter to the positive side of your new volt meter. Connect the negative side of your volt meter to a good ground. Don't worry about the "fused" business unless you want the guage not to read when the car is off (not having an SPF wiring diagram in front of me). In that case, just feed the positive from anything that is turned "off" when the key is off.
EDIT -- Don't forget there's usually a feed for the little background light.
