No matter who does it make sure no splicing is done to the truck, Nissans are finicky when the wires are messed with and then you'll regret it. Plug and play is a great thing.
Your location isn't in your profile so if you needed help nobody would know if they could help you.

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.

Nissans are so tempermental I won't add a remote start system to my wiring. Too many stories of Nissan owners getting electrical gremlins down the road.
Too bad they don't sell a plug and play remote setup.

So correct me if I'm wrong , to pull the pop up camper I need the class 4 hitch receiver and wiring harness installed ? Is that it

Buy the heavy duty receiver and 7 pin wiring setup so you never have to revisit this again. Even buying it from Nissan it's not that bad but you definately better off that way. If you weren't so far from here I'd do it for you. Just always take the safest route and option in trailering.
