Using this pack is easy. First, gather your 22 - 26 AWG wires. Then, take the included crimp pins and use a crimping tool to attach them to your wires. After that, place the wired pins into the provided housings to create the male Futaba J 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 prevent the pins from rusting. If you have any extra pins, keep them safe for future use. That's it! Enjoy creating your custom cables with these connectors.
