Correct Voltage regulator for 100amp Single wire Alt?

Imagine what happens when you find the directions (found HERE on FABO!)
Now that I have the single wire alt wired correctly with new heavier gauge wires
(charging nicely with revs) -thank you very much, what use is the Voltage Regulator on the firewall. I am using a new set of gauges (Summit) under the dash, pretty much ignoring the factory idiot lights in the cluster, except the speedo and fuel gauge.
Just unplug the thing and remove to VR?????
What will I be killing??
