Using these 1×16-pin crimp connector housings is easy. First, take a wire with a pre-crimped terminal. Insert the terminal into the housing. Do this for all the wires you need to connect. You can then use the custom cable you've made with different 0.1'-spaced connectors, such as male or female headers and solderless breadboards. When handling these housings, be gentle to avoid any damage. Keep them in a dry and clean place to prevent corrosion. If you notice any signs of wear or damage, it's best to replace the housing.
