Hello and Thank You for the question - You will either need to remove the face of the unit to find the connections ,or you may need to remove the unit from its cage, or there will be a small cover that you remove on the unit to expose the connection. Once you have located the connection to the unit there will (should) be a white, black, and green wire. On the replacement cord you will have the same colors. Match the colors and secure with wire nuts. There will also be some sort of a cord clamp to secure the cord to prevent it from pulling out of the unit. Re-assemble and you are finished. If your cord is the flat type with 3 wires along side each other the middle wire is the green (ground). Let me know if you need more information about this, I'm here to help - just ask.
