Whether you're a contractor on your way to the jobsite or just a casual fisherman heading to the boat landing, you need working trailer lights to tow safely and legally. For any towing setup, CURT offers quality wiring components, including complete wiring kits, circuit breakers, wiring connectors and more. This relay kit is made for certain years of the Nissan Armada and Nissan Titan without a factory tow package. It is recommended for applications where over-protection is required. The kit includes two small blue relays and one large brown relay that are required to complete the circuits for a trailer wiring connection.
