Hello all,
So, I've decided to take the plunge into doing my own build. I'm converting an US Dominix stunt saber to one with sound and a new LED unit to take advantage of the Clash on flash feature. I've spent countless hours on these forums reading, reading and reading some more. With copious breaks of course to watch some amazing Youtube videos.
Here is my wiring diagram. I think I've done it right, but please point out anything that seems wrong or if I could do this better.

Other than making sure my wiring is correct, I have a couple other questions.

Will the LED holder module work in the Dominx hilt or is it too big?

I noticed in the description of the V6 chassis that it says it's not compatible with the pre-wired NB4? I was hoping to use the prewired version and cut off the JST connectors. I feel pretty confident about soldering wire to wire, but wire to sound board makes me a little nervous.

Thanks everyone and MTFBWY!
