Wiring is extremely easy. There are two connectors, one is a 3-pin, other 2-pin
The 2-pin connector is the Battery positive & ground
The 3-pin connector goes to your stator (yellow wires)
Note: my 2013 has a 2-phase stator, hence has 2 yellow wires. Most bikes (suspect the newer V7s) has the usual 3-phase stator. If you have a 2-phase unit, connect the 2 yellow wires in any of the 3 pins. If you have 3-yellow wires stock, you have a 3-phase unit and will connect each yellow wire to each pin on the regulator (order doesn't matter).
