quick update. I tried posting twice now but I guess it gets lost in the spam box because I put links in it.

I installed the spindle, and replaced its junk connector with a quality one.
Wires inside the spindle were smaller than I expected, 22ga or so.
Also they had blobbed silicone inside to seal it up. There are 2 o-rings that should do the job. I'll see for sure once I clean it all up and reinstall the cap permenantly. I'll probably leave it under vacuum to check for leaks. I'm not trying to have water running through the wrong parts of this thing.

Also I've got some backlash in my Z leadnut. I'm going to try replacing the tension o-ring with a smaller one. If that doesn't help, I guess a little misalignment will do the trick.
