I have a 2013 Nissan Xterra. It has factory harness installed already. What do you mean by "need hardware"? Do I need the clips and the 2 bolts?

Clips bolts yes. You also need the signal lever with fog light switch above headlight switch. Without it the factory harness does not work. It cost $110. Better off getting the oem package for about $200

My 2014 challenger came with the harness in place. Just pulled back the fender well and the wires were there.

No, it's not. You will need a harness and a dash kit, also if you want the steering wheel features you need the module interface

Well it depends. In my Volkswagen all I needed was the wiring harness that connects from the stock harness to the aftermarket, and of course the end connectors. I also needed a harness for my antenna, but that's Volkswagen for you. I would say once you receive your deck look at the back and then figure out what you need. You may need to add a dash install kit depends on the size of your stock stereo.

You use some of the existing hardware clips already installed on vehicle and it comes with additional hardware that slides onto the vehicle.

The hitch works perfectly well with out a wiring harness. It is just not legal to tow a trailer of any type on public roads without at least brake lights and turn indicater lights, often that includes tail lights and a license plate light for trailing at night.So, in practicality, yes you need the harness. I found the Curt harness to be well made with good clear simple to follow instructions and easy to connect. Make sure that you get the exact one for your particular year, make, and model car.

It has everything needed. I used my own wire harness but it included one that would have worked.

You will need the harness because it depends on your vehicle different cars have different cables and also the frame so it looks good in the dash board but these two things 1) harness 2) frame are really cheap just buy them on amazon or local audio shop

No. Not without you buying a bunch of hardware and some ingenuity. I got it work but I would not recommend this product for the Xterra

They attach using the existing factory mounting holes. Everything you need is included. Very easy to install.

Comes with bolts, nuts, and clips. Installed them on my 2007 wrangler X in about 20 minutes.

I don't know about the Nissan, but with my ford, it was money well spent to buy the custom rail brackets instead of using the universal ones. You will go through a ton of drill bits otherwise and may still not get a good fit.

I installed this on my Subaru Forester XT and it plugged into the factory harness...it is a tight fit but you can install it with no cutting or splicing

You'll need the adapter to match your car's harness unless you want cut and hack your harness. You may have to mod mounts/bracket depending on your car. You will need the double din mounting kit including front plate cover. You do know this unit does not have a built in cd/did player right?
