    2- And 3-Wire Systems

    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.


    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.


    Curt SMT Circuit Boards

    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.


    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.


    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. To do this, you will need the Curt powered converter wiring kit (55151 - sold separately), which contains the power wire that connects your battery.


    Then 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.

    I didn’t like the way it cut into the vehicle wiring, so I bought an OEM harness from Mazda for my 22 CX5. My dealer gave me great instructions and nice sealed connectors. YMMV- I think trailer is a great company and will do business again. The hitch I bought is FANTASTIC.

    Installed easily on my 2019 Sprinter RV. Works well which is something I could never say about the Sprinter tow system. Thanks to etrailer for the advice and excellent training videos.

    I installed this on my 2004 bmw325 and it was an easy install and it has worked great.

    I can't believe I have to use this universal kit for my Corolla Cross just because it is an XLE and you (Curt) cannot figure out how to make a plug and play kit like for all other models of Corolla Cross.

    Fast delivery , easy installation

    Installed this kit on my 2022 VW Passat. It works good however finding the right wire was a challenge. I wish that there was a plug and play taillight converter available.

    I have used this products before , these are for stock on future builds . Good price and quick srvice

    Still working great. Absolutely no problems. Had to tap into the fine wires on my 2006 Nissan X-Trail near the spare tire. Also brought a higher gauge wire from the battery via a fuse in the engine compartment routed under the car. Highly recommended.



    by:

    great product! I had the local UHaul install this product. So far it works real good



    by:

    Have purchased a number of hitches and wire harness for a number of different vehicles I have owned. All products were easy to install and worked perfectly . The instructions were clear and quality of their products is top notch. I have used their customer service to ensure I was ordering the right product for a older vehicle (75 Toyota Landcruiser) they were patient and ensured I got the right set . Their customer service is matched by their pricing and that would be hard to beat . Delivery (Canada) was exceptionally fast. Probably not my last order and I have recommended this company and their products to my friends. If your considering a purchase I don't think you will be disappointed and you will be saving lots of money doing it yourself.

    Quick service! haven't installed yet, but appears to be all that I needed.

    • LED trailer lights
      Yes, the Curt Upgraded Circuit Protected Powered Tail Light Converter part # C56496 will work perfectly with LEDs on a trailer. The wiring harness draws power from the vehicle's battery so you don't have to worry about faults with the vehicle caused by the amp draw of LEDs on a trailer.

    • Where are the Towing Light Fuses on a 2015 Jeep Grand Cherokee
      I checked the owner's manual for your 2015 Jeep Grand Cherokee and found all of the locations you need to check that relate to the trailer lights. There are several so it is certainly possible that you missed a few but I don't see any relays. These fuses are all located in the power distribution center (PDC) or aka fuse block under the bonnet next to the engine. There may also be fuses in the interior fuse panel but I was not able to look the locations up for you. F29 20 Amp Blue – Trailer...

    • Why Is Trailer Wiring Converter Harness Needed for 2007 Cadillac SRX
      In a lot of vehicle the turn signals are separate from the stop lights which is different from how trailer lighting works. That's why a converter is needed to match the circuit styles. Also a lot of vehicle't taillights can't handle the amperage draw of the trailer taillights so the power has to come from the battery which is what the # C56496 also allows.

    • How to Replace Just the Converter Box of a Curt Trailer Wiring Harness
      You could cut the old converter box out of your # C56164 and then install the converter box of part # C56496 in it's place. Normally we recommend to check the trailer wiring for any shorts and fix as necessary before connecting new trailer wiring so that the new box doesn't short as well. But since your trailer is brand new and works with your other vehicle you would most likely be fine.

    • Tips for Finding Taillight Wiring on Hatchback Vehicle
      What you will need to do is find the rubber conduit that carries the wiring from the hatch lights to the door frame of the vehicle. Typically this is at the top of the door. If you look for a black rubber hose that runs from the hatch to the door frame that's what you need. Inside this will be the wiring for the taillights. You will need to use a circuit tester like what comes with the # C56496 to test the wires to find the correct circuits.

Part number # C56496 and part # 56146KIT that also includes the wiring and fuse holder for routing the power wire of the kit up to the vehicle battery.

    • Turn Signals Intermittently Working While Running Lights And Tail Lights Work
      If the signals are trying to draw more power when in function, but are only working intermittently, I would first check the ground contact point. This will be the white wire from the converter box. Make sure you have a clean, maybe even bare metal surface to give you a solid ground connection. You can use a little sand paper to remove any paint or coating to this surface that might hinder a quality connection when grounding. Also look for any possible kinks or bends in the power from...

    • Troubleshooting Right Turn Signal Flashing Fast with Curt Wiring Installed on 2022 Mazda CX-5
      Thank you for your purchase of the Curt Upgraded Circuit Protected Powered Tail Light Converter # C56496 for your 2022 Mazda CX-5! Normally when we see hyperflashing like that it means there is a bad connection somewhere on that circuit. So what you'll want to do is check the fuse for the right turn signal on your CX-5 and if that looks good then look at the spice connection you made for that function. Be sure the connection is secure and nothing along the wiring is damaged. Another thing...

    • Trailer Wiring 4-Way Harness Recommendation for a 2005 Subaru Baja
      For your 2005 Subaru Baja there is a trailer wiring option confirmed to fit, but not a T-connector type that would plug inline. Instead you would need to use the hardwire kit part # C56496 that is a universal fit kit that will work on your vehicle. This is the best priced option we carry as well.

    • Why Would Trailer Wiring Stop Working on Trailer When Headlights come On
      Try improving the connection of the main ground wire of the trailer wiring harness. Make sure it is attached to a clean metal surface. Or you can run all of the trailer wires back to the main ground. This is actually the ideal solution. But you can also check the current grounds for the lights to make sure they are making a solid connection to a clean metal surface. What you described is the classic insufficient ground scenario so finding a way to improve the grounds will fix the problem....

    • Does the Curt Upgraded Circuit Protected Powered Tail Light Converter Draw Power While Not In Use
      The Curt Upgraded Circuit Protected Powered Tail Light Converter - 4-Pole Flat Trailer Connector part # C56496 only draws power from the vehicle while a trailer is attached and the lights are activated. Therefore, you don't have to worry about it draining your battery without a trailer attached. If you choose, you could remove the inline fuse on the power wire that leads from the battery to the converter box but this would not really have any affect so I just recommend you leave it inside...

    • Replacement Trailer Wiring Converter Recommendation to Replace Shorted One
      To replace the bad converter box you could use the # C56496. This will allow you to wire the converter to existing wiring of your vehicle and will come with a new 4-way connector. You will want to check the wiring of your trailer to find what shorted out your current converter before you replace it so that you don't short out the new one as well.

    • Troubleshooting Trailer Wiring that Stops Working when Vehicle Headlights are On
      What you described is a classic ground issue. The problem is that the added amperage draw of the head/running lights being on for your vehicle makes the trailer taillights a bit weaker. What you would want to is run the grounds of the light assemblies of your trailer back to the main ground harness of your trailer. I can almost guarantee that will fix the problem. I attached a help article for you to check out as well that covers 4-way troubleshooting.

    • Will Curt Trailer Wiring for a 2015 Acura TLX Short Out
      The only people that have problems with the Curt trailer wiring part # C56496 burning out are the ones who do not properly secure the converter box. If the box comes loose and starts banging around it will eventually burn out. Aside from that it is an excellent option that has been confirmed as a fit for your vehicle. We don't have any confirmed fit T-connector style harnesses for your vehicle so I am not sure if they have your vehicle confused with a different one like a regular TL.

    • Trailer Wiring Availability for a 2013 Kia Soul
      I was able to find a trailer wiring harness that will work on your 2013 Kia Soul, but the Tow Ready Harness # 118431 that you referenced has not been carried over to the 2013 models. Curt recommends the Curt Circuit Protected Powered Converter # C56496. This is a kit that will require you to hardwire to the wiring of your Soul, but it will work well for you. I attached installation instructions and an install video for you to check out.

    • Troubleshooting Installation Of Curt C56496 On A 2023 Chevy Bolt EV
      I did not see any mention of connecting the black wire on the converter. In order for the Curt # C56496 to function properly, you will need to connect the black wire to the battery in order to power the converter. If you do not have the black wire connected this will explain why you are getting low voltage out of the converter. You can use the wiring kit # 55151 to run power to the converter module.

      If the trailer wiring was working properly why do you need to run that additional wire to the converter? It sounds like that is the problem. Only one source for the right turn and stop light circuit is needed. What you will want to do is test the wires going into the box of the converter box for voltage with a circuit tester like the # 3808 to see if there is voltage going into the box when the taillight functions of your vehicle are applied, and then test the output side of the box to...
