Nitehawk-36 strain relief without cut/recrimp?

You don't. You almost always need to recrimp unless you want a big bundle or floppy wires handing off the toolhead.
Cool. Thanks! Where do you normally get those connectors?
thanks! and that works for power too - was worried the higher amps might burn through?
I think they can but I don't recall what they are rated for. You'll have to dive into that.

The cables to the LDO stealthchanger kits came with one end crimped but not plugged into the connector shell.
Can you maybe release the pins from the shell and re-insert after assembly (you may need to bend back the latch but that's straightforward).
Then, my printer doesn't have any openings where the connector does not fit through. It's very tight (I rounded off a few corners) but it can be disassembled by unplugging. I paid attention to this for the option of swapping out printheads later (one connector, one config file). The strain relief on the head would be the only reason I'd need to assemble the cable without connectors, everything else works with connectors on.
The clips on the umbilical itself are slotted (at least the variant I use, printed in TPU95) so they can be clipped onto a cable.
BTW, sherpa mini, got those too (CNC, FYSETC IIRC). Had to mod the backplate for Anthead (where the TPU "sock" with umbilical/PTFE tube/steel support attaches), ping me if interested.

Hey thanks @endstop and @NoGuru ! Appreciate your feedback. Update on what I ended up doing:
Noticed that JST PH2.0 was rated for too low amps (Docs say toolhead board is speced for 5A), and since the original cable uses microfit, I just ordered some new ones and that worked pretty well!
If anyone stumbles onto this in the future, I followed this guide and used this tool for the crimps. Also used very small tweezers to properly seat each crimp in the plastic housing. Also noticed that in newer versions of the umbilical cable shipped out by LDO there isn't a grounding wire for the sheathing, so I just skipped that pin all together.
Now @endstop - thanks for the offer for the modded backplate! Always interested to see what others are using. Right now I'm using this with a pg7 gland and it seems to be working pretty well.
I haven't added the clips, etc. for the umbilical since I don't have any TPU right now. But eventually I'm going this route. For the time being, I am using this exhaust plate with one of those pg7 glands, and its working decently. Again, since I don't have any TPU yet I just have some paper towels stuffed in the extra toolhead slots.
