You simply twist the bare wires of the LED light cords onto the power supply bare wires and then cover in electrical tape or heat shrink tubing. One power supply can power many LED lights in this way.
It is important to only use a "regulated" 12vDC power supply with the LED lights. "UNregulated" power supplies can send too much voltage to the lights and burn them out.
