Looking for these connectors, I need male and female, 3 and 4 pin. What are they called and where can I find them? Preferably uncrimped pins would be nice so I can crimp them myself and not have to solder and use heat shrink. Links to a website are greatly appreciated, Thanks in advance.
I believe what you’re after is 3 and 4 pin JST SM plugs and receptacles.
@Kyle_Halvorson - If you want to make your own JST connectors then go to @Jason_Coon ’s Tree V2 webpage at:
https://evilgeniuslabs.org/tree-v2.html
Scroll down to the parts list and Jason has a link to where he purchased his JST connectors and the crimping tool to make your own.
I purchase mine on eBay with the wires already connected. Make sure you get the ones with the lower gauge wires if you get then on eBay.
yup…JST plugs…I made my own for awhile since I needed longer header cables & jumpers between strips, then I found our friend Ray Wu makes a 1m jumper and then he custom made me some 30cm jumpers…well worth at least MY time making them 
the connectors and pins and crier can be found at element14/ Newark electronics
Awesome, I’ll look into all those, thank you!
eBay or Aliexpress just search for… 3 and 4 pin JST SM
exactly what Marc suggested
I always cut those off and throw them out lol
@Cristian_Martinez I keep them, but I want brand new ones to crimp myself to send to my customers. Haha
Lol. I bought smaller 3 pin JST plugs. And i have tiny 2 pin JST plugs for my batteries as well
I get them from AliExpress, they’re 2.54mm JST connectors. This is the most common size but other sizes are available. The Japanese crimping tools are the best, but normally only available from Japan!
Yeah and shipping takes forever… 
@Jeremy_Spencer what brand are the crimpers? Do you have a model number or part number?
The info is in that link to Jason Coon’s post. Just search eBay or Aliexpress for SN-048b. Don’t look for a brand name there go for the cheapest you can find.
Oh gotcha, ok.
Thanx @JP_Roy ill probably buy some too lol
i just bought a hundred jst sm connectors from aliexpress, i haven’t found out which tool to buy though

Japan Solderless Terminal, in case you were wondering 
I use “engineer pa-20” and “engineer pa-21” crimping tools. Sorry for the late reply…
