Curt Wiring - C56236

Install a 4-way flat on your vehicle with this splice-in harness. Potted, SMT construction boosts water and vibration resistance. Works with 2-wire, 3-wire, and PWM systems. Requires wiring kit (C55152 - sold separately) to connect to battery.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Ensures that your vehicle's wiring matches that of your trailer
    • Works with 2-wire, 3-wire, and pulse-width modulation (PWM) systems
  • Constructed using surface-mount technology (SMT) for consistent, reliable performance
    • Maximizes trailer light yield and intensity while producing minimal heat
    • Ensures superior operation in rough road conditions
  • Resists water and vibration thanks to potted enclosure
  • Connects directly to your vehicle's wiring with the included quick-splice connectors
    • Requires Curt powered converter wiring kit (C55152 - sold separately) to connect to your battery
    • Color-coded wires and wiring guide ease installation
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 5 amps per circuit
    • Tail lights: 7.5 amps per circuit
  • Limited 1-year warranty


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. This converter will also ensure that your trailer's lights illuminate fully, even if your vehicle has pulse-width modulation (PWM) wiring. Note: This will not affect how the tail lights on your vehicle operate.


When used with the Curt powered converter wiring kit (C55152 - sold separately), this converter offers circuit protection and 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.

I bought the converter wiring kit along with the taillight converter to install on my 2006 Mini Cooper. The kits included everything I needed to do the installation, except for a 6/ 12V tester, which I was able to get locally at a hardware store. The instructions were clear and easy to follow, so the full installation time was about 30 minutes. In fact, I did the installation on my lunch break in my employee parking lot. A quality kit for a great price, would recommend. 436532

Ask the Experts about this Curt Wiring

Do you have a question about this Wiring?


  • Where Does Curt Trailer Wiring Harness C56325 Install on a 2017 Cadillac XT5
  • The Curt wiring harness # C56325 is designed to replace the factory 4-Way flat on models of the 2017 Cadillac XT5 that came with a 4-Way connector from the factory. You can check on your XT5 to see if it has the factory connector to plug the Curt harness into. The factory harness should be located behind the rear bumper about in the center of the vehicle. I have included a link to a video below of a difference harness that installs the same way so you can use it as a guide to locate the...

  • Trailer Hitch and Wiring Recommendation for 2017 Volkswagen GTI
  • I checked with Curt and they do recommend the universal fit trailer wiring harness part # C56236 as a fit for your 2017 Volkswagen GTI as a fit. This is a universal fit harness though that will require some hardwiring. The other option is the no-splice Tekonsha kit part # 119250KIT which uses sensors to tap into the taillight wiring instead of requiring splicing. The Curt Trailer Hitch, part # C11412 is a confirmed fit as well and would work great. For a ball mount you would want...

  • What Trailer Wiring Harness Do I Need If My Vehicle and Trailer Both Have LED Lights
  • I do have an option for you but the Hopkins Plug-In Simple Vehicle Wiring Harness part # HM11143175 is not designed to be used on a vehicle with LED tail lights. The issue is that the LED lights do not carry enough of a load therefore what we call a powered converter is needed and for that I recommend using the Curt Tail Light Converter with 4-Pole Flat Trailer Connector part # C56236 which will work with both LED lights on the vehicle and trailer. However, this harness as you can tell...

Now for wiring we have universal wiring kits like the part # C56236 which are a confirmed fit. Or, if you wanted a wiring harness that does not cut into the wiring of your vehicle at all we have the ZCI part # 119250KIT which would also work well. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with...

  • Which Trailer Wiring Harness is Recommended for 2011 Audi Q5
  • For your 2011 Audi Q5 the correct trailer install harness is the part # C59236 that you referenced. Your vehicle has pulse width modulation taillight wiring which is what the Curt harness is designed to work with. The brown wire of this harness (for the running lights) needs to get grounded on your taillight setup.

  • Best Trailer Wiring Harness for a 2018 Chrysler Pacifica L
  • The best trailer wiring harness we have for your 2018 Chrysler Pacifica L is the Curt Tail Light Converter with 4-Pole Flat Trailer Connector part # C56236. This kit will require you to splice into the vehicle's factory taillights but as there is not a custom plug and play kit available for the L trim package this will be your only option. In order to find the correct circuits to splice into on your Pacifica you will need to obtain a circuit tester. While you have the signal active,...

  • Recommendation on a Trailer Hitch for Either a 2017 Infiniti QX30 or a 2017 Mercedes-Benz E-300
  • The Curt Trailer Hitch # C11454 is a custom-fit hitch that fits the 2017 Mercedes-Benz E-Class. This Curt hitch is a Class I hitch with an 1-1/4 receiver opening. The gross tongue weight is rated at 200 lbs and the gross towing weight is rated at 2000 lbs, but you will want to check the owner's manual or with a local Mercedes-Benz dealer for this vehicle's weight capacity. If the vehicle has a lower tongue weight capacity, then you will want to abide by that capacity You will also need...

  • Which Curt Trailer Wiring Harness is a Confirmed Fit for a 2010 Audi Q5
  • Actually the Curt harness part # C56236 that you referenced is essentially the most recent version of the now discontinued C56200KIT. For your 2010 Audi Q5 the # C56236 is the recommended universal harness. The YouTube video you found that shows the older harness being installed on a 2010 Audi Q5 like yours would still work as a guide.

  • Recommended Trailer Wiring for 2013 Audi S5 Convertible
  • I'm glad to hear that you're happy with the hitch you purchased! Curt hasn't tested a wiring harness on your vehicle, so they couldn't make a recommendation. The correct harness will depend on what kind of wiring system your S5 uses. You'll need to use a circuit tester like part # 40376 on the circuits feeding the taillight assemblies to determine whether your vehicle uses a 3 wire or a Pulse Width Modulation (PWM) system. If you discover that the running light, turn signals and...

  • Separating Brake and Turn Signals on 2018 Ford F-150 with Pulse Width Modulation for Compatibility
  • You have the pulse width modulation figured out using the Curt Tail Light Converter with 4-Pole Flat Trailer Connector # C56236 but there is not a combined splitter option with a PWM converter. I personally prefer the Upgraded Modulite Vehicle Wiring Harness Kit with 4 Pole Trailer Connector (Includes Install Kit) # 119147KIT for the converter or the heavier duty # 119190KIT. We see less issues over time with the Tekonsha converters compared to the Curt brand. You will still need to...

  • Can Curt Trailer Wiring C56236 Install in Vehicle with LED Taillights
  • The Curt wiring harness part # C56236 can be used on a vehicle with LED taillights because it draws all of the amperage needed for illuminating the trailer lights from the vehicle battery. You need to use the power kit part # C55152 to make the connection to the vehicle battery. Basically it just uses the taillight circuits as signal wires and draws all the amperage from the battery.

  • Trailer Hitch Recommendation for 2006 Volvo XC70
  • The Curt hitch for your 2006 Volvo XC70 # C12318 is what i would recommend for you as it has the higher weight capacities and is made in the USA. Then for trailer wiring the part # C56236 will be your best option. With Class I hitches like this you have to use the required ball mount that the manufacturer specifies. So for the Curt hitch you'd need the # C45016 which has a 2-5/8 inch rise or 3-1/4 inch drop. If your trailer needs a 2 inch hitch ball you'd want the part # A-82 or for...
