Curt Manufacturing 56225 Vehicle-Side Custom 4-Pin Trailer Wiring Harness,Fits Select Nissan Frontier,Pathfinder,Xterra,Suzuki Equator ,Black

I am 64 years old. In the old days, to install harnesses, one would need to locate, mark, strip/cut, and splice wires to rig a harness. This was amazingly simple. I had a hard time finding the 12 pin plug behind the kick plate. The plug was tucked behind the other plugs and had no flexibility to pull from the wall of the truck. However, it turned out to be very simple. The instructions that come with this package show various steps of progress. However, for a novice such as myself, the instructions were missing information. A quick online search for videos, explained the other steps and within no time, all was connected and mounted. My test light indicates all is working properly. My boat has been in the shop. I am assuming all will work upon connection. Knowing one's way around vehicles is also important. On my Frontier, the kick panel is accessed by prying off the sill at the bottom of the door. Then unscrewing the black plastic retainer holding the kick plate. This retainer is on the upper floor board under the glove box area. One must also understand how to disconnect auto wiring plugs without damaging the clips. Between installing my new hitch and this harness, I would estimate it took this idiot about 2 dedicated hours. A person that has the right knowledge could have installed the hitch and the harness in about 30 minutes.

Lightning fast installation. Literally took me less then 7 minutes to install the wiring and relays. Everything works including running lights. Took me about 3 minutes to get the cap off the connector under my truck to plug it in. My truck is a 2012 Nissan Frontier SV. Definitely money well spent.

Love the ease of this install. Literally plug and play.Install in less than 20 min.

The item worked as advertised and as expected.

Easy to install on Xterra. Plugs right in. Now I have running lights on the trailer.

This works as advertised and installation was super easy. I’m only downgrading to 4 stars because the exposed pin where the trailer hooks up to got loose really fast like it’s about to break off. Not sure if it had some defect but I connect it carefully each time and everything still works as it should.

Very good

You have to have the 3 way relay harness. No tail lights otherwise. Easy to install, nissan xterra is plug and play for trailer towing wireing. Got it all on Amazon. Although ebay has it also.

I researched a lot because my trailer marker lights would not work. Turns out Nissan has some weird lighting system that requires you to purchase an add on to make the marker lights work on a trailer. The trailer wiring and hitch was factory installed. It was easy to install and now my lighting system works! Highly recommend this if you have a 2018 Nissan Frontier Pro4X. Priced right too.

Perfect fit and quick install, less than 15 minutes and I had working trailer lights on my Nissan Frontier.

Need this harness to set my 2013 Frontier SV ready to tow a camper.All factory plugs are already there. Really easy to install.I have also buy a 4 & 7 pins connector for the back and the front connector to plug the brake controller.All work great.

Everything I needed was in the package,and everything fit. The trailer lights all worked on the first try.

Neat and tidy and plugged into factory wiring.
