Those are the ones. Figured I'd wait till I was in the office before replying instead of replying with "I'll send a link once I'm in the office" lol.
5 was plenty for me. I'm only using two. It depends on your setup.
If you're going with the aurora, it has 4 channels, so you would hook 4 of these up in-line between the actual LEDs (coming out of the hood) and the drivers (in your stand). This is how I have it set up:
It's not pretty, but it works, and it'll make it much easier to remove the hood than if the cables are still attached to somewhere in the stand. This is such a simple step, I'm surprised that for the cube retrofit kits they don't already include some form of quick disconnects.
You could look at something like
this, which will hold 8 wires in one single block, but you would need a crimper, and if you ever have to substitute something on either end, you have to re-crimp/connect that pair of wires, and if you ever want to switch drivers or LED strings or anything, it would just be a lot more complicated to disconnect than if it had it's own separate connector. But then it's just one neat clean rope of wire.
Make sure to do your heatshrink and/or sleeving before putting in the final connectors!
