## Overview

The CURT 56285 Vehicle-Side Custom 4-Pin Trailer Wiring Harness is a plug-and-play solution tailored for select Volvo XC90 models. It enables quick, no-fuss installation without cutting or splicing, providing a reliable 4-flat trailer connector for tail, brake, and turn signals. Built with surface mount technology for efficient power delivery and equipped with a dust cover, this harness ensures durable, weather-resistant performance for all your towing adventures.

## Description

If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Volvo XC90 (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great value!
  

*by B***C on Reviewed in the United States on May 27, 2024*

I installed this in about 30 minutes on my XC90, directions were a bit all over the place, but i watched the video on you tube and that made it a breeze. Saved me from paying someone over $100 to do something that took no time at all.Have not had any issues with this and have used it many times already.A lot of people were complaining about warning lights and such... If it is installed correctly you won't have that issue.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Fit my 2018 XC-90, installation made sense to me.  All wires were long enough to do their jobs.
  

*by C***R on Reviewed in the United States on May 2, 2022*

Instructions could have had better images, especially for tail light connector on the passenger side.  It still only took me 15 min or so to install it and get functional Tail lights on the trailer.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Flawless installation despite bad instructions. Watch the eTrailer video.
  

*by J***F on Reviewed in the United States on November 4, 2023*

Instructions were pretty much useless but the eTrailer YouTube video was very helpful. Wiring works perfectly. Spring for the Curt tester.
