Do I Need A Tail Light Converter?

Difference between 2 wire systems and 3 wire systems

Some vehicles operate on a 3-wire system, wherein the brake signal and the turn signals run on separate wires to illuminate different lights. (Typically, these vehicles have amber turn signals.) But most trailers run on a 2-wire system, which means the brake and turn signals travel along a single wire. You'll notice that, on your trailer, the brake light will flash for the turn signals.


If your vehicle operates on a 3-wire system, it will need to be converted so it will be compatible with the wiring system of your trailer. This is where a tail light converter comes into play. This converter lets you combine the brake and turn signal functions of your vehicle so they run on a single wire to properly activate your trailer's tail lights.


This particular converter also works with newer types of vehicle wiring, like PWM. Pulse Width Modulation (PWM) is standard on European vehicles.


Powered by Your Battery

This converter won't overload or cause damage to your system because it pulls power straight from your vehicle's battery. So you can be sure that your trailer lights will activate no matter what type of bulbs your vehicle has - or your trailer, for that matter.

Powered Tail Light Converter Installation

This kit comes with all the wiring you'll need to convert your vehicle's lighting system to match your trailer's. The powered converter box has splice-in wires on one end and a harness with a 4-way flat vehicle-end connector on the other. It also comes with a power wire that will connect to your battery so your electrical system doesn't get overloaded.


To begin the installation, use a circuit tester (sold separately) to double-check the function of each wire on your vehicle's tail light wiring harness. The color/function of the splice-in wires on this converter may not match the color/function of those on your vehicle, so you'll want to be sure to check all of the wire functions first. Once you've figured out the functions of your vehicle's wiring, use the included quick-splice connectors to connect the corresponding wires on the trailer connector. Quick-splices, or "wire taps" offer a quick way to make connections without you having to strip and twist wires. Just place the wires in one of the taps and snap the cover down.


Using double-sided tape, stick the converter box to a flat surface inside your vehicle near the tail lights. It's helpful to clean the surface so the tape can adhere fully.


Once the converter box is spliced in, you need to run the power wire up to your battery. Be sure to remove the fuse before connecting anything so you don't blow it! You can put it back in once everything has been installed. To hook up to your battery, you'll need to disconnect the negative cable from your battery and attach the power wire to the positive terminal with the included ring terminal.


How to find a grounding point

Find a raw, unpainted metal surface to use as a grounding point and secure the white ground wire using the provided self-tapping screw. Cleaning the surface prior to securing the white wire will ensure your converter is fully grounded. Finally, secure the converter wires to your vehicle using included cable ties. If you have a 2-wire system, the red brake wire will need to be grounded as well. You can do that in the same way, using an extra ring terminal (sold separately). Finally, secure the converter wires to your vehicle using included cable ties.


Quick Tips:

  • Butt connectors - especially heat-shrink ones - provide the most secure, longest-lasting connection, so we'd recommend you grab a few and swap them out for the quick-splices in this kit.
  • Use a circuit tester on the plug terminals once the harness is installed to make sure everything's working. There's nothing worse than figuring out that you have a bad ground or a faulty connection right before you're about to hit the road.
  • Be sure to put a little bit of dielectric grease on the 4-way plug to protect the terminals from dirt, grime, and corrosion.

Built Using Surface-Mount Technology

Curt SMT Circuit Boards

Curt builds each tail light converter using surface-mount technology (SMT). This construction method involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a smaller circuit board that provides more routing area and that offers superior performance, reliability, and durability.


Circuit boards constructed using SMT perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, increasing durability and lifespan. In addition, lower resistance levels ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.
