## Overview

The CURT 58240 is a compact, waterproof 3-to-2 wire splice-in taillight converter designed for reliable trailer wiring on vehicles without custom harnesses. It features color-coded wires for fast installation, requires no additional power sources, and is intended for interior mounting on vehicles with traditional bulb taillights (not compatible with LED systems). Ideal for professional-grade towing setups seeking a dependable, long-term wiring solution.

## Description

When your vehicle does not readily provide an electrical connection for hooking up your trailer, CURT electrical converts offer the solution. Working tail lights on your trailer are absolutely essential any time you tow, and a converter provides an effective way to properly equip your vehicle for safe towing. A CURT electrical converter, much like our custom vehicle-to-trailer wiring harnesses, provides a trailer connector on your vehicle by splicing into the vehicle's electrical system. Electrical converters are designed to splice directly into the taillight wiring, rather than plugging into various sockets, giving them the nickname "taillight converters". Though it requires a little extra work compared to a custom wiring harness, a tail light converter offers a reliable, long-term connector solution. This CURT electrical converter is designed to convert a 3-wire system to a 2-wire system.

Review: This unit was a great problem solver, just be sure to order the one you need as there are several different ones for different applications. My particular one was wiring trailer lights on a school bus that had individual turn and brake lights. Unit has worked flawlessly since installing.
Review: I brought this thinking it would work on my Australian 2021 SR5 Toyota Hilux. I wanted to use one of those UTE LED tail light strips as they don’t have a seperate wire for the brake light. Instead, they use the turn signal to trigger the brake LED. So if that’s what you’re trying to do, this device won’t do it.

## Features

## Questions & Answers

**Q: I want my marker lights and then signals to be the same bulb. can i use this for that? they're also leds**
A: this turns you stop and turn to the same bulb, not marker and turn signal. And you still have to wire in running and ground. In the title it says Not Compatible with LED Lights, so NO you cant use it with LED's.

**Q: Is this same configuration made to use with led lights?**
A: I believe so. LED lights are only different from conventional bulbs, other than their brightness, in the required power they use. They use very little compared to old style lights thus the wiring to feed them can be a much smaller (thus cheaper) gauge. You should have no problem using this. Tim.

**Q: Will this work on a 6-bolt negative ground system?**
A: It works perfectly on 12 Volt but I doubt it would on  6 Volt

**Q: Is this LED conpatible**
A: Don't see why not, as long as your flasher unit is led compatible

### ⭐⭐⭐⭐⭐ Review
*by C***N on 29 April 2024*

Hooked the wires up as indicated on the module. Wasn't working quite right for the trailer lights. I changed the flasher to an aftermarket Wagner one - then worked perfectly. Not sure how I came to that conclusion about trying another flasher but it worked. Says it not for trailers with led lights, haven't tried it though. They make powered ones for trailers with led lights. You don't need any additional hookups for this one, like a 12volt power source.
