Running Lights Not Working After Installing Wiring Harness On 2015 Nissan Frontier

Question:

I bought and installed the C56225 trailer wiring on my 2015 Nissan Frontier. I have brake and turn signal lights working on my boat trailer but i dont seem to be getting any power for the running lights on the power pin in the connector. Should I have power there when I turn the truck lights on? DO I need another harness to get the trailer running lights?

If you have the trailer wiring harness, part # C56225 installed on your 2015 Frontier and everything works but the running lights, you may need an additional relay like part # C57000. This is located under the driver side dash to the left of the steering column as shown in the attached photo.

Nissan did install the relay on some vehicles but failed to do so on others.
