    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.

    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.

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

    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.



    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.

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

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

    • 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...

    • Recommended Trailer Wiring Harness for a 2014 Volkswagen Jetta GLI
      Correct, the GLI models have different tail lights so you won't be able to use a plug-in trailer wiring harness. That said, we do still have an option in the Curt Tail Light Converter with 4-Pole Flat Trailer Connector part # C56496 which will hardwire directly into the wires behind the tail lights. It provides a 4-pole/4-way connector which is the most common and widely used. If you don't already have a trailer hitch picked out then I recommend adding the Curt Trailer Hitch Receiver...

    • Testing Trailer Wiring Converter Box to Determine if it is Damaged
      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...

    • Does 2003 Mercedes ML320 Need Brake Controller to Activate Trailer Brakes
      Sounds like the brake lights circuit of your trailer wiring was either accidentally or intentionally ran to the brake output circuit of your trailer wiring which is why your brakes lock up when the brakes are touched. You do need a brake controller to take care of applying the brakes as full 12 volts from a light circuit will always lock them up. A brake controller will vary the voltage of the circuit to give the brakes the correct amount of pressure. The easiest solution is the Curt...

      It will definitely be worthwhile to test the wires behind your trailer plug. This way we can know if the issue lies with the receptacle itself, or with the vehicle wiring harness. To replace just the receptacle, you can use the Curt # C55774. If you are needing to completely replace the vehicle side wiring, we suggest using a 4 flat harness # C56496 along with the Universal Install Kit # ETBC7. There are no plug-and-play options for this truck so this will require cutting and splicing...

    • Could Install of Curt Trailer Wiring without Disconnecting Battery Damage Converter
      It is possible that you created a short during the install of Curt trailer wiring harness part # C56496 which damaged the converter. If you can test for voltage with a circuit tester like part # PTW2993 on the input size of the wiring and see that there's voltage going in but none coming out that would indicate that the box is shorted out.

    • 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.

    • 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...

    • 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....
