It says "V2," but this wiring diagram is still valid:
http://www.saberforum.com/index.php?topic=6717.0It doesn't show the buck puck, but that goes between the LED+/- on the board and the actual LED+/-. However, a buck puck isn't necessary. You can calculate the amount of power needed for each LED and add resistor(s) to the positive or negative wires to perform the same function. However, the buck puck is more efficient. It will deliver the correct amount of power needed to each LED die and your color(s) won't dim as the batteries get lower. It's up to you what you want to use.
