Using these female crimp pins is quite easy. First, pick a 22 - 28AWG wire that you need. Then, crimp the pin onto the wire. After that, snap the crimped pin into the crimp connector housing to make your custom cable. When using these pins, make sure the crimping is done tightly so the connection is stable. Store them in a dry place to avoid rust. If you notice any bent pins, try to straighten them gently. That's all you need to know to use and take care of these pins.
