Curt Wiring - C56196

  • Trailer Connectors
  • Converters
  • 2-to-3 Converter
  • Curt


When your vehicle does not readily provide an electrical connection for hooking up your trailer, Curt electrical converts offers 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 a Curt custom vehicle-to-trailer wiring harnesses, provides a trailer connector on your vehicle by slicing into the vehicle's electrical system. Electrical converters are designed to splice directly into the tail light wiring, rather than plugging into various sockets, giving them the nickname "tail light 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 2-wire system to a 3-wire system.


  • Converts a 2-wire electrical system to 3-wire
  • Intended for a vehicle being dinghy towed behind an RV or other vehicle
  • Constructed with SMT circuitry for better performance and durability
  • Color-coded wires for easier installation
  • No heavy-duty flasher or direct battery connection required
  • 2.1 Amps per circuit
  • 1-Year limited warranty

Curt 2-To-3-Wire Tail Light Converter - C56196

i used this on my trailer so that i was able to use taillights with separate (amber) turn signals, it works like it is supposed to, BUT it doesn't work with LED tails bc it drops the brake wire voltage coming out of the convertor to 10v causing the brake light LEDs to not function properly; i solved this issue with a voltage regulator (10-32v in - 13.8v out) so if you've got a little wiring knowledge or are using incandescent taillights then it will work great for you. 651911

so far its still working just like it did since day one, no complaints so far.

Used it to wire up a third single brake light bar on a teardrop trailer. Works well. OEM trailer lights are LED which necessitated the choice of this controller over the standard controller. Written and graphic wiring instructions posted by etrailer were easily followed, and so far, after a year of use, no issues. Thanks. 640215

It works as described under normal circumstances, but I have one problem with the hazard flashing. Using it makes the brake lights light up on my trailer and not the turn signals like on the car. I still have to do some research on that issue. 421306

The CURT 2-to-3 wire conversion kit was easy to mount and install. Upon fist glance, there seemed to be an issue with the quality of the plastic box, and where the seems did not meet. However, the longevity of the part is yet to be seen. The converter was marked clearly, and instructions were good. I used the converter for a Swedish boatwashing machine that was imported into the USA. The European style connector was removed, and the CURT conversion kit was wired in. After wiring up the inputs and outputs as labeled on the part itself all lights worked independently just as they should. Great product with ez to understand instructions and works as it should. 695277

This item is exactly as advertised. I use it to convert a U.S. Spec vehicle with red turn signals to pull a E.U. trailer with the yellow turn signals and works like a charm. I have ordered several times from this company and continue to receive excellent service from the ordering processing all the way thru to the delivery. Would recommend both this product and the company to anyone asking. 526377

I found a camper shell for my Ranger that had an LED brake light, but it had never been wired up before. Before I found this product I had simply spliced a connection into one of the vehicle's brake light circuits. While this DID work, it also meant that it would flash the turn signal from the side that I wired it into (I used the left side; Ford used amber turn signals on the Ranger from 1993 to 1999, but mine is a 2011). This would have confused anyone behind me whether I was slowing down, turning, or both with too many flashing lights at once. This tail light converter was the solution to this problem. An ordinary converter (3-to-2 wire) will NOT work b/c it can't be wired in backwards (tried it before on a similar project). Same for this one (it even says it on the labeling) except it works in the opposite direction (2-to-3 wire). I wired it in the same way as just the light itself, & nothing happened. Eventually I found out it needed power from the left AND right brake lights for it to function. EUREKA! Everything lit up when I pressed the brake pedal. I also found out that the hazard flashers run through the brake light circuit in the converter after being separated from the turn signals--the brake light still flashed along with them (but ONLY them); the same thing happens with the high-mount stop lamp on my Wells Cargo trailer, so I can live with that. Had to find extra wiring to reach the right side though. Only suggestions are to make the the input wires longer & explain in the instructions that you need the left AND right inputs for the converter to run properly. Otherwise an excellent product! 552854

Purchased a set of European style taillights for a trailer rewire I was doing. Got everything wired in and couldn't get the taillights to work properly due to they had a 5 wire configuration, after some research found that over seas the turn signal and brake signals are separated on trailers, in the states ours are combined on one signal wire, thus they're wasd no way to make these lights work, until I stumbled upon a forum and there was a link to etrailer and what do you know here's this little black box that does what I need. I ordered it but yet was hesitant cause I really didn't think it would work. Once installed all works perfect. I stil got to use my taillights I wanted on my rewire and everything works just as normal. 711304

Works like charm. Easy install. This application was used for my chevy avalanche to meet the foreign countries specifications on lighting requirements. Simple wiring solution to split the turn signal from brake light signal. 401969



- C56196
by:

Does what it says it does. Internally, it uses a relay that triggers when both turn signal inputs are activated, so there is a pulse on the output when hitting the brakes, or when the cautions are activated. I used this to install turn signal / marker light combos on my trailer. This stops the brake light functionality from lighting up the turn signal portion of the marker lights, but there is still a brief pulse or strobe when the brakes are hit, or the cautions are activated. I would have personally used a mosfet in this unit instead of a relay, as the switching and signal processing would be orders of magnitude faster with no pulse or strobe effect. So, it does separate out the brake lights from the turn signals, but not 100%, more like 95% 388962

  • How To Add Third LED Brake Light On Trailer
    If you would like to add a third brake light that is LED I recommend to use the Curt 2-To-3-Wire Tail Light Converter part # C56196 because it is more compatible with LED lights in our experience compared to the Tow Ready version part # 118158. Since your trailer has a combined wiring system the the converter will separate it so the third brake light will only come on when braking. I also recommend to use diodes to prevent feedback with Roadmaster Single Park Light Diode part # RM-690....

  • Does the Tail Light to Tail Light Converter # C56196 Work with LED Trailer Lights
    The converter # C56196 will work with LED lights. However because LED lights draw less power you may see some bleed over (the lights faintly lit when they should not be) but it will not be as if the lights are full on and it will only really be noticeable at night.
