For starters, you need wire wrap (most commonly 30 AWG silver-plated copper wire with Kynar™ insulation in a variety of colors), a wire wrapping/stripping tool, and preferably some machine tooled wire wrap sockets. While you can wire wrap just about any pin, machine tooled wire wrap sockets provide a 0.025" square post specifically designed for wire wrapping tools, and the connections will be much more secure. You may also find it more than helpful to utilize wire wrap socket ID markers. Because all of the wrapping is done from the underside of the socket, the ID markers label the pins so you make the right connection.
