The voltage regulator plug should be a direct swap, 2G to 3G.
Do you currently have 3 wires (or 2) on the voltage reg plug?
Do you have any of the wiring that came with the 3G, like the plug for the Voltage regulator? And if so did it have 2 or 3 wires on the original VR?

Are you wanting to be able to swap back to stock 2G ALT?

I plan on keeping the option open to be able to use both types of ALT so i can keep the old 2G behind the seat as a spare.
