If 1, then you need to get the above linked module.

If you have 3 wires, then the wire going to the 2 wire plug, labeled as #1, needs to wired from the ignition switch, then to the alt light bulb, then to the alternator spade labeled #1. This is the "field" wire, that needs to be energized to create a magnetic field, so the spinning alternator will create a charging voltage / current. The spade wire labeled #2, is the voltage sensing wire for the internal regulator, and is usually best connected to the fuse block hot, although many people jump it over to the Bat wire.

Just one wire
