Thanks for your question, Dale!
The Brake Buddy Classic 3 part # HM39494 will pull power from your Xterra's battery. You will also want to pick up the charge line kit part # RM-156-25 so that you can keep the battery charged when flat towing. We also have the Curt RVi Series towed battery charger part # RVI74FR. What's really cool about this one is that based off the color of the LEDs it will tell you the health or status of your vehicle battery.
Let me know what you think or if you have any more questions.
