Started building my Low Rider V4 and realized that I had no end stop wires.
The V1 shop is currently out of stock.
Can find dupont connectors but all the kits I’ve found have very short cables.
Where can I find cables long enough preferably with dupont connectors already installed?
Yea, my search found the same. I don’t know for sure but wouldn’t be surprised if they were back in stock soon.
A couple options I can think of.
- Get the stepper extender wires and either some of the 2 cable housings or just take them off shorter wires. Theyre just held on with a little tab. Each of the extenders would get you 3 really long ones.
-
Get the short ones and some wire to splice together. I like the heat shrink solder seal butt connectors. Or solder and heat shrink tubing.

I gave in and bought a crimper and connection kit. Dupont aren’t terrible (especially after doing some of the smaller ones and buying 3 crimpers until I found ones I liked).
@jeyeager Which crimper do you like? I think I’ll buy one too.
It takes a little practice no matter what one you use.
I find the iCrimp IWS-2820M the easiest by far. It is non-ratcheting and requires crimping the wire and the insulation separately, but I think that simplifies the process. It’s not fast, but I can crimp reliably and see what I’m doing.

Having a decent pair of wire strippers and wire cutters helps a lot too. I use these:

For ratcheting crimpers, I still use the iCrimp IWS-3220M sometimes too. They work ok with a little practice and do crimp both parts at the same time.

I also have the iCrimp SN-2549 as well. These were the first ones I bought and I hate these. I have a really hard time getting a good crimp with them. Just getting the wire positioned correctly is really frustrating.

Thank you
I opted for a small gauge wire from a local electronics DIY store, same size as stepper wire. One end I soldered to the switch, other end crimped. I was terrible at it, so probably for each crimp on average I tried twice before I succeeded. The crimper I have was purchased from LIDL of all places. It cost about 20 EUR, included all the required crimps, the tool and the connector plastic bodies.
If you have access to shorter version of the required wires already crimped and you don’t want to crimp, probably extending the short wires by soldering would work and be more cost effective if you have the soldering iron, solder and flux laying around, compared to buying a crimper for a one off project.

I think youll find continual use for a crimper. That is a good tool to have.

Jamie recommended SN-025 for DuPont connectors. Crimps enough so that connectors fit inside the plastic shells without putting up a fight, which is something that SN-28B would often cause. Have been happily using SN-025 ever since …

I used to hate crimping. But, over time, with the right tools and some practice/experience it’s become tolerable. Useful skill if you’re likely to keep making, breaking and repairing things…
IWS-2820M mentioned by Jason has been helpful for various situations too, including getting a crimp started for more specialized tool.

I have a ratchetting crimper with dual dies, similar to the SN-025, but not an iCrimp.
It could be the version of the tool I bought, but it seems like good quality and I subscribe all my issues to operator error. Trying to get the end registered properly in the tool and keep it from rotating with limited eyesight and dexterity is challenge for me.
I find the IWS-2820M to be much easier personally. Each crimp may theoretically take twice as long, but in practice it does not - the more open design makes each individual crimp much quicker to set up than trying to get proper alignment in the dual jaw. Also, when I get to the fourth crimp on a 4 pin connector and bugger it up so badly with the dual ratchetting type that I damage the wire and have to re-do all of them I grab a beer and am done for the night, so wiring that way can take weeks 
I now mostly just buy pre-wired/crimped connectors, cut them to length and splice with heat-shrink butt connectors and only crimp when I have to. A little more expensive, but more reliable and far less frustrating for me.
I do agree that good strippers and cutters are worth every penny.

Let me repeat that coz it’s important: Good strippers are worth every penny!
To the point: It was Aza who said I should try again with crimping and for some unexplainable reason I listened… and I am happily crimping those tiny a**oles like a pro 
just kidding, I just do it okish but it works and is so much better then soldering.
I do recommend the tool from iCrimp 2820M.
