I actually know the solution. I just went through it. It's a very long story, and I cannot tell you how mad I am at the Nissan Dealership in Grand Junction, Colorado, for not knowing the answer to this question right away. It has cost me over $500 and 500 miles of driving to learn the location of this tiny fuse holder. Look straight up above the brake pedal and accelerator pedal (under the dashboard) and see a wiring harness that plugs into the "Body control module" above the steering column. You should see two mini fuse holders sticking out of this harness. They are whitish in color, like a gallon milk bottle. One is for the right trailer turn signal, and one is for the left.
This is the only year Nissan Frontier where this is true (as far as I know) it is the result of a recall on that year where they installed this harness. If your truck went in for the recall, then you will have the same harness located in the same place. Good luck, Bob Walker, Moab, Utah

There should be a 30 AMP mini blade fuse in the fuse box under the hood that you are probably missing. I assume that since you got the relays with the wiring kit, that you got the kit from a Nissan dealer. If that is true, there should be a fuse in the kit also- in a sealed bag that has the "trailer wiring harness owner's manual" in it.
Hope this is helpful!

mine was the same way the fuse was pulled out. the fuse box is on passenger side of consoul it is the frist fuse on top to left.
SOURCE: i just installed the 7 pin factory trailer harness
In the passenger side behind the plastic kick panel there is a control module that works the trailer lights, if you got the towing package. My lights were malfunction and it turned out the unit in the kick panel was not wired up properly from the dealer. Have a dealer check it or get the installation diagrams from a nissan dealer or the web and investigate your module on your own. Best of luck.

you have a short... a bad ground somewhere. sorry i cant be more specific but if you have a wiring diagram you can find the ground for this... possibly corrosion but unlikely. good luck

You'll need to disconnect the wires from either the truck connector or the trailer connector...
I highly suggest purchasing a voltage checker- it looks like a screwdriver with a pigtail of wire with an alligator clip on the end. The tip of the 'screwdriver' has a point for probing. The light in the probe will light up...makes it easy to trouble shoot without a helper behind the trailer.
Hook the aligator clip to a good positive grounding point on the bumper or frame(not painted).
then pin by pin on the truck connection, stick the probe on each terminal tab.. and write a simple diagram where you find brake, tail, backup, etc...
Then i'd suggest, taking the connector off of your trailer, exposing the wire ends.
Run again thru your diagram and turn on each light of the truck. As you do, touch the wires from the trailer to that specific terminal. (make sure your ground wire is attached on the trailer) you can mark each wire with a piece of tape and label it which is which.
then simply attach your trailer wires according to your diagram to the terminals in the connector... that should get you in business..
hope that makes sense...
That way if the factory wiring harness remains the same, you'll be able to use it with other trailers if the need arises..

Update, I found the fuses. If you don't know where to look you'd never find them. They control the LH and RH turning signals on the trailer. They are in a small white connector together by themselves. Way up under the dash by the steering column. No were near any other fuse. They are standard 10amp fuses. Luke
