Question:
Guys, Your videos are great but somehow it seems my 2012 Pro 4x looks different than your videos. The truck came tow ready and everything works except my running lights for the trailer. My blue relays are under the hood in a fuse/relay box see pic and both signals work, brake lights, and flashers. I only lack the running lights. I have also tested every fuse in the box and cannot find a bad fuse. I also checked under my dash L of driver and there is one lone relay. Wasnt able to remove it but not certain of its function. I am truly at a loss of what to do next. Greatly appreciate any suggestions.

Finding the trailer wiring relays of Nissan vehicles like your 2012 Nissan Frontier can be somewhat challenging but since you already checked the panel under the hood and behind the dashboard the location you will find it at is behind the kick panel on the passenger side of the vehicle.
I attached a picture that shows which panel I am referring too. I also attached a link to a video that shows how it's accessed and where the relays harnesses are as well. This blue relay from the Curt Relay Kit # C57000 will activate this circuit.
