## Overview

The CURT 56357 is a vehicle-specific 7-pin RV blade trailer wiring harness designed for select Nissan Pathfinder and Infiniti QX60 models. It offers a heavy-duty, plug-and-play connection that supports all essential trailer lighting and braking functions without any cutting or splicing. Built with durable rubber housing and a spring-loaded dust cover, it ensures long-lasting, weather-resistant performance for hassle-free towing.

## Description

CURT custom wiring connectors and harnesses are the easiest way to outfit your vehicle with a trailer wiring connection for towing. Each one is custom-fitted to work with a specific make and model. This particular 7-way RV blade socket is designed to be a custom wiring option for certain years of the Nissan Pathfinder and Infiniti QX60 (see application info to verify fitment). It provides a universal trailer connection for the tail lights, brake lights, reverse lights, turn signals, electronic trailer brakes and auxiliary power. 7prong taillight wiring can be used as a replacement or new wiring and is typically used for towing fifth wheel and gooseneck trailers. This 7 way female outlet comes with all necessary hardware to establish a solid connection, as well as a dust cover to keep the connector socket clean when not in use. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this factory tow package socket is not equipped on every vehicle, a CURT custom wiring connector (also called a T-connector) utilizes the socket for simple, stress-free installation. Instead of cutting, splicing and soldering into your vehicle's wiring system, the custom wiring connector uses a single OEM compatible plug and instantly provides a standard vehicle-to-trailer hitch wiring connection. To ensure long-lasting reliability, all CURT custom tconnector wiring is thoroughly tested for optimal functionality.

## Questions & Answers

**Q: will it work for a 2022 pathfinder?**
A: No

**Q: The description saus this will work with 2018 nissan pathfinder the amazon message says it will not. is this compatible? thanks.**
A: I have a 2916 Pathfinder and installed it on my vehicle.  I had to watch a UTube video to get it to work.  Once I did it worked great.  My Pathfinder has a tow package with towing controls inside or I would have had to have someone else install additional equipment in the vehicle, such as trailer brakes and transmission cooling.  Find a UTube video for your model car before buying and then you can check your car if it has the plugs this kit will need.

**Q: My fuse panel already has 2 blue fuses in the “open cavities (N)” Should I replace these with the ones from the kit or leave them in there?**
A: Mine had the fuses too, I just left them and kept the ones they sent just in case.

**Q: The pictures show this having a 4 pin in addition to the 7.   Is that accurate?  As the description never mentions it**
A: Mine only had 7 pin
