Just asking. Your truck doesn't have the trailer connector under the bumper? If it's not there you may want to look around up underneath and see if the harness is there but just not connected to anything. I'm probably wrong but it was my understanding that they all used the same wiring harness from the factory and just didn't use what they didn't need to for that particular truck. That might save you some hassles down to road and if it's in place you know it will work correctly. Just get the factory connector, mount it, and plug it in. Splicing is fine if done correctly. However, most places that install anything take shortcuts and use those little "quick splice" connectors. THEY WILL FAIL! Not today, maybe not for a few years but around here (yep, Pittsburgh also) with all of the crap they dump on the road every time they see a snowflake it will get into them and then their done. Just vibration can cause them to fail. I DO NOT USE THEM UNDER ANY CIRCUMSTANCES.

I agree with Clint. If your going to add something as safety important to your truck or most anything else go with the factory item. It's made to work with your vehicle and you know it will fit. Sometimes spending the extra is worth it. Just wondering if for some reason Nissan has a computer(s) monitoring the electrical system. Even if they don't and you splice into a circuit that uses a supply(+) and a ground, NOT A CHASSIS GROUND, and YOU use a chassis ground you are asking for trouble. That might be where people are having issues. There is always a reason something is wired without using a chassis ground. Normally because whatever it is needs a floating ground. If you don't then many BAD THINGS can happen. We added some LED fog/work lights under the rear bumper of my sons (Vaethund) truck as extra back-up lights and wired them directly into the trailer harness. We used the wire for the trailer back-up lights and the ground wire in the harness. Everything soldered and sealed with heat shrink nice and neat and have had no problems. We didn't need to use the ground wire as we were only adding some lights and a chassis ground would have worked fine but why not use whats there and not worry about the ground connection getting corroded and not working down the road.
