Using this pack is easy. First, gather your 22 - 26 AWG wires. Then, use a crimping tool to attach the included pins to the wires. Next, insert the wired pins into the housings to form the male JR connectors. When using the crimping tool, make sure to apply enough pressure to secure the pins properly. Store the pack in a dry place to avoid any damage to the components. If you're not using the spare pins right away, keep them in a safe spot. And that's all you need to know to make the most of this male JR connector pack!
