Running Lights Not Working After Installing New Trailer Wiring on 2015 Nissan Frontier
Question:
no running lights on 2015 frontier sl new installed trailer light wiring

This problem is usually caused by the lack of a running light relay. On the 2015 Nissan Frontier, there is a relay harness that must be installed behind the passenger side kick panel. This harness uses two blue relays, one of which activate the tow package running lights, and a larger brown relay for the 12volt battery charge circuit.
If the wiring harness you installed did not come with the relay harness, then you will need to purchase a wiring harness with the jumper harness like part # C56225 for a 4-way trailer connector. The jumper harness is not available separately.
If you have the jumper harness, but you are missing the relay, then you can use one of the blue relays from the
Curt Relay Kit # C57000. I have attached an installation video on a 2015 that shows how to install the trailer connector and the relay harness for you to check out.
