These housings work with our wires with pre-crimped terminals and our crimp pins to let you quickly make
custom cables that mate with various 0.1"-spaced connectors,
including male and female headers and solderless breadboards.

and snap them into the housings
(note: it’s not easy to get the wires back out, so plan carefully!).

You can easily make cable harnesses or assemblies that branch from one connector on one side to multiple
connectors on the other; you can also cut off one pre-crimped end and solder the wires
directly to components to make swapping connections easy:
