Wiring in a volts gauge.

I'm in the process of redoing my dash and want to bypass the gauge in the cluster and wire in an aftermarket gauge.

Do I use the factory connection? Do I just connect those to wires and wire the gauge elsewhere?

The electrical system is not part of my clear understanding in some areas.

i did this bypass Bruce. then i wired my volt guage to a switched hot out of my fuse box and to ground.
