## Overview

The CURT 55341 Vehicle-Side Custom 4-Pin Trailer Wiring Harness offers a vehicle-specific, plug-and-play solution for Toyota 4Runner owners needing a reliable 4-way flat trailer connection. Featuring advanced SMT circuitry for durability and a dust cover for protection, it eliminates cutting or splicing, ensuring a fast, secure installation that powers your tail, brake, and turn signals with OEM precision.

## 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 Toyota 4Runner (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.

Review: Perfect fit for '98 4runner - Worked perfect for my 1998 4runner. Plug and play.
Review: Works - Works great easy to install plug and play. Design is different from the original the plug cable goes in the other side but you can just keep the cable in the trunk compartment. If you really wanted to run the cable through the bumper you could but you would have to either make bigger holes or cut the cables and reconnect them.

### ⭐⭐⭐⭐⭐ Perfect fit for '98 4runner
*by A***Y on August 11, 2025*

### ⭐⭐⭐⭐⭐ Works

### ⭐⭐⭐⭐⭐ Perfect fit for 2000 Toyota 4Runner
*by S***E on June 17, 2026*

Exact fit for 2000 4Runner!! Super easy to install! I watched a YouTube video before installing so I would know how to remove the necessary panels. No drilling or modifications required. It was a little tricky getting the 4-pin flat plug thru the portion of the bumper that exits just above the spare tire, but only because the plug was a little bulky in comparison to others. This harness is literally plug and play. The connectors are male/female style so it’s impossible to plug into the wrong wire. I simply disconnected the battery before installing. I used a piece of electric fence wire to pull the wire thru the holes. Any stiff wire will work to fish thru the holes to attach the wire to so that it can be pulled to the other side. I chose this route instead of leaving wire beneath the carpet where abrasion could damage and/or short the wires. I highly recommend this product. I initially search for a Hopkins brand but the specific part number for this model of Toyota has been discontinued. I was unsuccessful finding another suitable harness before stumbling across this one. The reviews gave me enough assurance it would work and they proved right! I will come back to this brand the next time I need a harness.
