Using these 2x13-pin crimp connector housings is easy. First, take one of the pre-crimped terminal wires and insert it into the housing. Make sure it fits snugly. Then, you can connect the housing to different 0.1-inch spaced connectors, such as male or female headers or solderless breadboards. When handling the housings, be gentle to avoid any damage. Store them in a dry and clean place to keep them in good condition. If you notice any signs of wear or damage, it's best to replace them to ensure a reliable connection.
