## Overview

The CURT 59236 Weather-Resistant Multi-Function Splice-in Trailer Tail Light Converter Kit is a universal-fit, epoxy-sealed wiring harness that converts multiple trailer wiring systems into a standard 4-pin output.

## Description

Rain, road grime and salt can deal a vicious blow to your trailer wiring, and it takes electrical components with an extra-thick shell to stand up to the elements. The CURT multi-function electrical converter is an advanced taillight converter that offers the ultimate in vehicle compatibility and weather resistance, giving you a reliable wiring connection any season of the year. The potted design seals the internal electrical components in a watertight enclosure and is filled with a solid compound to protect against impacts, vibrations and moisture for long-lasting use, even on the exterior of the vehicle. The converter also features our advanced surface mount technology (SMT), using smaller components mounted directly to the surface of the circuit board. This produces lower resistance, reduced heat generation, longer life cycles and higher reliability. The CURT multi-function electrical converter comes with pigtail wires that are able to be spliced into two-wire, three-wire or PWM wiring system with combined stop and taillights. It converts any of these systems to a simple two-wire system, using a standard 4-way flat output, to be compatible with most trailer wiring. The converter is controlled using a microprocessor that is able to sense the current passing through it, allowing for quick reaction to dangerous conditions such as overload and short circuits. It also filters unwanted input signals to protect your wiring systems and uses a mere seven volts for low-voltage operation. The CURT multi-function taillight converter is a heavy-duty electrical converter for virtually any vehicle-trailer combination. It comes with color-coded wires and an easy-to-read wiring guide, as well as a dust cover to protect the 4-way flat connector. This package includes a powered converter wiring kit #55152 and four snap locks for faster, more secure splicing.

Review: Good price, easy to install! - Installed on Mercedes 2010 ML350. Installation was straightforward except that since the main module has to be placed on the right side of the car, the left turn signal wire was short and I had to extend it. It would have been nice if the manufacturer had longer turn signal wires for both left and right to make it easier for users to place the module on either side of the car. Extending the cable was easy enough and the unit worked as intended. The shop wanted $150 to install it in addition of charging retail price for the unit; it takes less than one hour to install everything for a newbie!
Review: Know your wiring code colors on your car for brake lights - Easy install instructions were a plus and user friendly I highly recommend this For your vehicle have been a mechanic for over 40 years and it was an easy install

### ⭐⭐⭐⭐⭐ Good price, easy to install!
*by P***D on May 25, 2025*

### ⭐⭐⭐⭐⭐ Know your wiring code colors on your car for brake lights
*by M***I on January 8, 2026*

Easy install instructions were a plus and user friendly I highly recommend this For your vehicle have been a mechanic for over 40 years and it was an easy install

### ⭐⭐⭐⭐⭐ Great kit for my 2011 Audi Q5
*by C***Z on August 9, 2016*

Worked great in my 2011 Audi Q5. Wire just hides inside under the cargo floor and then hangs out over the bumper when in use. Instructions must be found on the internet. I had it wired wrong at first where the trailer lights only worked when the back hatch was open, so I dug around and found a different way of doing it and it works now. Overall easy installation with everything included. - Oh, you should get the smaller snap splicers from an auto parts store for 20-22g because the Q5 has tiny wires. Remember that your lights must be on too when testing. :) Get it!
