So, there are quite a few of these, and I've found many more searching around.
Just wanted to be sure I'm getting things right:

subjects:
NBv4
powerex
Red/Green/Royal Blue Cree XP-E2 CopperNova
resistors

Speaker is fine; first 2 pads on nbv4
third pad, activation, goes to switch +
L1/L2/L3 are where the negative of each led goes: 2 straight from the leds, one going through the extender (from what I've gathered, it doesn't matter which goes where, right?)
- pad led negative, battery negative and extender negative goes here
+ pad all the led positives and the battery positive.

Question, where do i put the resistors?
I have a dynaohm (should be between led positive and NBv4 I think), a 0.5ohm resistor I've seen it used both on positive wires and negative wires, which is the correct way/ and a 1.2 ohm resistor (should be for the red I think) likewise seen it used both on negative and positive.

Thanks for your time, I will try and post a diagram if things arent clear enough
