Using these crimp connector housings is easy. First, take your wire with pre - crimped terminals. Then, carefully insert the terminals into the 2x12 - pin housings. You can now connect your newly made custom cable to male or female headers or solderless breadboards. When handling the housings, be gentle to avoid any damage. Store them in a dry place away from dust and moisture. If you notice any dirt on the housings, use a soft, dry cloth to clean them. This will keep your connectors in good working condition for a long time.
