If you installed a trailer wiring harness on your 2012 Nissan and the running lights are not working, then you may need to install an additional blue relay under the driver's side dash. You can use one of the blue relays from the Curt Relay Kit # C57000 for this. For some reason Nissan included the running light relay on some models but not others, even if they did not come with a tow package.

The location for the running light relay is behind the driver's side dash to the left of the steering column (see photo).

Answer 5

On the Nissan vehicles sometimes the running light relay circuit is behind the dash panel to the left of the steering. I'd check there since the relays are good behind the passenger side kick panel.
