They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this special 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. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Nissan Frontier, Nissan Pathfinder, Nissan Xterra and Suzuki Equator (to verify your vehicle compatibility, see application info). It comes with all necessary hardware to establish a solid connection. It also comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality. Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it. ## Features - Plugs into existing OEM vehicle socket to provide a 4-way flat socket - Simple plug-and-play design eliminates the need for cutting or splicing - 4-way flat output connects tail lights, brake lights and turn signals - Dust cover included to keep connector clean when not in use - Slit loom keeps wires contained and well protected ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B00SZ5GOXY | | Best Sellers Rank | #284,870 in Automotive (See Top 100 in Automotive) #539 in Towing Hitch Wiring | | Brand Name | CURT | | Cable Type | Flat Ribbon | | Connector Type | 4-Way Flat | | Customer Reviews | 4.6 4.6 out of 5 stars (757) 4.6 out of 5 stars | | Global Trade Identification Number | 00612314562251 | | Included Components | Custom Wiring | | Item Dimensions | 9 x 6 x 3 inches | | Item Type Name | Nissan Frontier, Pathfinder, Xterra, Suzuki Equator | | Item Weight | 13.12 ounces | | Manufacturer | Curt Manufacturing | | Material Type | Plastic | | Model | 56225 | | Number Of Items | 1 | | Number Of Packs | 1 | | Part Number | 56225 | | Recommended Uses For Product | trailer wiring | | Unit Count | 1 Count | | Upc | 612314562251 | | Warranty Description | 1 Year Limited Manufacturer Warranty | ## Product Details - **Brand:** CURT - **Connector Type:** 4-way Flat - **Item Weight:** 13.12 ounces - **Item dimensions L x W x H:** 9 x 6 x 3 inches - **Material:** Plastic ## Images ![CURT 56225 Vehicle-Side Custom 4-Pin Trailer Wiring Harness for Select Nissan Frontier, Pathfinder, Xterra, Suzuki Equator - Image 1](https://m.media-amazon.com/images/I/71enRjd-aqL.jpg) ![CURT 56225 Vehicle-Side Custom 4-Pin Trailer Wiring Harness for Select Nissan Frontier, Pathfinder, Xterra, Suzuki Equator - Image 2](https://m.media-amazon.com/images/I/71vfLqL-GbL.jpg) ![CURT 56225 Vehicle-Side Custom 4-Pin Trailer Wiring Harness for Select Nissan Frontier, Pathfinder, Xterra, Suzuki Equator - Image 3](https://m.media-amazon.com/images/I/A10wck2XOqL.jpg) ![CURT 56225 Vehicle-Side Custom 4-Pin Trailer Wiring Harness for Select Nissan Frontier, Pathfinder, Xterra, Suzuki Equator - Image 4](https://m.media-amazon.com/images/I/918qO0g05BL.jpg) ![CURT 56225 Vehicle-Side Custom 4-Pin Trailer Wiring Harness for Select Nissan Frontier, Pathfinder, Xterra, Suzuki Equator - Image 5](https://m.media-amazon.com/images/I/61KMYxigWNL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple plug and play *by on Reviewed in the United States June 21, 2026* purchased this trailer wiring harness for my 2022 Nissan Frontier, and I couldn’t be happier with it.
