Since there's three end stops that have wires that need to be kept track up, I'm illustrating two different ways of keeping them straight. The first is three different color pairings, white-white, white-black, black-black. The second is colored heat-shrink on the pairs to keep them together.
They're twisted to keep down interference since these apparently have high-ohm load resistors. In my designs I'd both twist AND use a lower ohm resistor to both reduce interference and to keep the contacts clean (a little current switched keeps contacts clean).
To get the connectors through the small heat shrink, feed one at a time.

Re: Wire marking/twisting
A very good idea! I have used cat6 patch cables and removed all the pairs and have used them for the endstops.

Re: Wire marking/twisting
Most of the low current wiring in my Max is now CAT-5 stripped. VERY nice wire.
BTW, what's with all the shielded 22 and 18 gauge wire that's stripped and used as regular hookup wire? Did SeeMeCNC get a boatload of that really cheap or something? That stuff is expensive.
Same with all the stainless hardware, have something against regular steel?

Re: Wire marking/twisting
Sometimes you run across deals you just can't pass up. I picked up a 1000 foot spool of shielded two-conductor 20-gauge cable for a mere $12 last year.
I've got a box of old serial cables I recycle wire from also...especially when I want already-twisted pairs.
As for labeling, I have one of the cheap Brother labelers from Costco. If I have a bundle that really needs a label, I just print one with a leader. It's a piece of tape once you take the backing off. Put the wires across the middle and stick the ends together to make a labeled tab. The labeler is also good for labeling panel switches and lights. And my parts boxes.
