  • Limited 1-year warranty


Installation

To determine where to splice into your vehicle's tail light wiring, you will need to consult the included instructions. Use the quick-splice connectors to attach the input wires of the tail light converter to the corresponding wires from your vehicle. To get the power necessary to operate, the harness must be connected to a 12V power source. This kit contains the power wire that connects the module to your battery, as well as the necessary ring terminals and butt connectors.


Once the harness is connected, locate a flat surface inside your vehicle near the tail lights and adhere the black converter box using the provided double-sided tape. Find a raw metal surface to use as a ground point and secure the white ground wire using the provided ring terminal and screw. Finally, secure the converter wires to your vehicle using the included cable ties.


It is recommended that you use a small amount of dielectric grease on the 4-pole connector to help prevent corrosion.


Powered Tail Light Converter with Surface-Mount Technology

Because most trailers run on a 2-wire system - wherein the brake and turn signals are carried on 1 wire - the signals from your vehicle may have to be converted to be compatible with your trailer's wiring. If your vehicle operates on a 3-wire system, which means that it has separate brake and turn signals, then those signals will need to be combined so that they run on 1 wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction 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 circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to 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, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


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

Video Transcript for Curt Wiring - Trailer Connectors - C56190KIT Review

Today we're going to take a look at the CURT Powered Taillight Converter Kit with the 4 way flat trailer connector. Now this is a custom fit part, it does fit many vehicles so what I would recommend is to go to our website, use out fit guide. Put in your year, model, vehicle and it will show you if this will work with your application. This will provide this 4 way flat trailer connector at the back of your vehicle, part of your trailer signal lights. It will ensure that your vehicle's wiring will match that of your trailer. It is designed to work with 2 wire and 3 wire electrical system.

The converter itself is constructed using SMT, which is surface mount technology, for consistent reliable performance. It will help maximize your trailer light yield and intensity while producing minimal heat. It ensures superior operation in any rough road conditions. It is also designed to resist water and vibrations. Now this will connect directly to your vehicle's wiring with these included quick splice connectors here. The color coded wires on this nice wiring guide here, that tells you which wire goes to where, will help an easy installation.

This other part includes is the battery power wire. You need to supply the power to this converter from your vehicle's battery. This part will include the battery power wire, the inline fuse holder, all the ring terminals, butt connectors, the fuse grounding screw and some cable ties to take up any slack in the wiring. Also comes with a nice set of detailed instructions on how to install it, also comes with this nice dust cap for your 4 way when you're not using it. Basically you just attach it onto here and then, when you're not plugged into your trailer, just go ahead and put your dust cap over that. It will protect the terminals from any damage or from the elements.

Now these parts are made in the USA, few specs on this converter. The maximum amp reach for the stop and turn light circuits is 7.5 amps per circuit. For the tail and running light circuit, it's 7.5 amps total. Briefly how you would install this is you go to your car. Now in your instructions, it will tell you where you would need to splice in these colored wires to your electrical wiring using these connectors. Once you get that all done, you would have a white wire left that you'll need to ground.

They do include this nice grounding screw that you can make your own ground. Then you'll be left with the black wire which is the power wire that will go to the vehicle's battery. What you want to do is this double faced tape they include, you want to stick this onto the converter and attach it to a nice, flat surface so it doesn't move around. Then to connect your power wire to your battery, is you got this length of wire. What you'll do is take one of your butt connectors and put it on the end here. Connect it to the black wire coming out of the converter, run your length of this wire up to the front to where your battery is. Take your other butt connector, put it on this other end, connect it to one end of your inline fuse holder just like that. Once that's connected, you'll take your other side of your fuse holder. Put the eyelet connector on and that will connect to your battery. You want to make sure you have your inline fuse holder between your connection to the battery. Once that's all connected, they include a 10 amp fuse. Just put your 10 amp fuse in the fuse holder, put your cap on and you'll be all ready to go. Again, you do have some extra cable ties to take up any slack in the wiring. That should do it. This is a review on the CURT Power Taillight Converter Kit with the 4 way flat trailer connector.

by:
2015 Honda Fit

I bought this kit for my 2015 Honda Fit. All is fine with three exceptions: 1. The green wire that runs over to the right side turn signal was not long enough to reach the right side turn signal wiring!!!! CRAZY, no excuse for that. 2. The blue connectors included do not work. When you clamp them down they do not make contact with the Honda Fit wires. Apparently the Honda wires are too small. Curt should know this. I had to remove all blue connectors and carefully squeeze the little metal plates inside the connectors so that they make contact with the tiny Honda wires. It was a frustrating pain in the rear to diagnose the problem and fix it. Come on Curt, FIX this issue. 3. Lastly, some of the Honda Fit wires were not the colors that Curt said they were. You must test all Honda wires, regardless of colors before making connections, not the end of the world, but confusing none the less . 316447

Do you have a question about this Wiring?


  • Recommended Trailer Wiring Harness for 2011 Audi S4
  • There is not a harness that plugs into your factory wiring without splicing so I recommend the Upgraded Heavy Duty ModuLite Circuit Protected Vehicle Wiring Harness with Installation Kit # 119190KIT. This will have the amperage you need whether you pull a trailer with incandescent or LED lights. I've attached a video of this installation on a Q7 to assist with the installation. I've also attached the installation instructions to help.

  • Curt Trailer Wiring Comparison for 2015 Honda Fit
  • The difference between the two Curt harnesses you mentioned is that the part # C59236 has a newer converter box which has a higher amperage rating than the older kit part # C56190KIT. For that reason the part # C59236 would be the better option.

  • Class III Trailer Hitch & Trailer Wiring Harness for 2013 Audi Q5
  • The Curt # C13136 and the Draw-Tite # 75940 2-inch Class III hitches share identical weight capacities but their designs differ and this will affect the complexity of the installation process. The Draw-Tite hitch installs in place of the aluminum bumper and this hitch requires a more involved installation than the Curt. I linked the instructions and an install video for both hitches to help you decide with which one you feel more comfortable. If it were me, I would go with the Curt in this...

  • We are happy to help with getting you the correct parts for your vehicle. For your 2013 Infinity JX35, the Curt wiring harness # C56281 you referenced is the correct fit for a factory replacement. The relays you need to install are not in the 6x6 fuse box according to my tech contact but rather in the small box by the firewall that is about 1-1/2 by 6 inches and has a black cover you will remove.

  • Left Turn Signal on 2012 Dodge Journey Stays On All the Time After Installing Curt Wiring Harness
  • First, let's make sure your are using the right wiring harness for your 2012 Dodge Journey. Wiring harness # C56330 is designed for models that have LED tail lights. If your Journey has regular incandescent bulbs then you would need a different harness # C56190KIT. It is important that the white ground wire be attached to a clean bare metal surface. There can't be any paint or coating of any kind. To test to see if the converter is the problem you can test it using a circuit tester...
