CURT 56225 Vehicle-Side Custom 4-Pin Trailer Wiring Harness for Select Nissan Frontier, Pathfinder, Xterra, Suzuki Equator

Easy to install. I never had a chance to test it until I need to a 1000 miles from home…. Worked perfect!

I installed this harness on 2015 Nissan Frontier. I found the instructions very clear. This was an easy DIY project. I used it to move my furniture using a U-Haul trailer. The trailer was a perfect match with this harness. I recommend this product.

Perfect fit on my 98 forester, no problems at all.

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.

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.

It's a good quality harness. On a 2008 Xterra, the harness under the vehicle was very easy. It was also fairly easy to install the harness that goes behind the passenger footwell kickpanel, but when I couldn't find the empty receptacle mentioned in the directions, I noticed a receptacle that was the same size, but had a plug already in it. I switched it out and everything seemed to work but then I realized that the passenger window had stopped working... I went back into the footwell, with a headlamp this time, and found the correct receptacle, which is a few inches further forward, and all issues were resolved. In summary, it is possible to plug this into the wrong connector. Just mentioning to help someone avoid the same silly oversight that I made.

As described, fast delivery. Thank you

Works well, made well, and good buy

Was happy with purchase but have not installed yet and not concerned as all was in order and ready to go. No let downs . Good Product..

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.
