    • Ensures superior operation in rough road conditions
  • Comes with dust cap for 4-way flat connector

    • Tail lights: 6 amps per circuit
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your trunk.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


Powered Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. 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.

Been a year and gets used daily. no wear and tear to speek of and the plug and play ease of install made it simple to install. They offer this as a universal kit as well but for the few bucks more purchasing the spacific kit for your car is well worth it.

update: 2 years now and still rock solid. I tow a small trailer every day, 7 days a week connecting and disconnecting the trailler and have had no issues at all with the power connections or the wires becoming frail or fraid. Simply a quality product thats proving to be durable over time.



by:

Video made it super easy to follow along. Everything you need is provided in the kit. Would advise a lift or ramp to create more clearance under the car but still able to complete, without one.

See what our Experts say about this CURT Custom Fit Vehicle Wiring

  • Fuse Blows on 4-Way Harness When Using Circuit Tester 2013 Jeep Compass
    It sounds like the 4-way tester you are using like part # I26 has a short somewhere which is in turn causing the 10-amp fuse on the Curt T-Connector Vehicle Wiring Harness part # C56344 for your 2013 Jeep Compass to blow. What I recommend doing is testing each circuit with a standard test light like part # PTW2993 to check for function. If all is good, then you know the problem was in the 4-way tester you are using. All of the converter boxes used in Curt's wiring harnesses are tested...

  • Will the Curt Trailer Wiring Harness for a 2015 Jeep Compass Kill the Battery With Trailer Unplugged
    The Curt T-Connector Vehicle Wiring Harness part # C56344 which is a confirmed fit for a 2015 Jeep Compass is an excellent option to power a set of trailer lights providing the most basic trailer lighting functions. The converter box will need to be powered via the vehicle's battery to minimize strain on the vehicle's tail light circuits. In regards to amp draw, there will be none without a trailer plugged in so you don't have to worry about draining the battery or unhooking the wiring...

  • How to Test Trailer Wiring for 2016 Jeep Compass to Determine if 4-Way is Functional
    Try plugging in a trailer to the 4-way of the # C56344 and you should find that it works fine. Testing the wiring on the input side of the box doesn't always tell you if the harness is working. If you wanted to further test the wiring though test the pins of the 4-way. The brown wire should have only running lights, yellow should have left turn/stop, and green should have right turn/stop.

  • Troubleshooting Trailer Wiring Harness for Vehicle Where Pin Stay Active All the Time
    Whenever a trailer wiring harness has a circuit that stays on all the time that means that the converter box like what comes with the # C56344 has shorted out and you'll have to replace it. Since these boxes don't short out on their own typically you'll want to go over your trailer's wiring looking for any obvious signs of shorts like corrosion or exposed wire and fix as needed. We've found that the most reliable brand of trailer wiring is the Tekonsha brand so for a new harness I'd recommend...

  • Troubleshooting Curt Trailer Wiring C56344 That Flashes Vehicle Brake Lights Then Shuts Them Off
    That is definitely not a good sign but it's most likely that you just need to unplug all of the connectors and plug them back in to clear any possible connector seating issues. Also make sure the power wire is connected to your battery and the fuse is good and installed.

  • Recommended 4-Pole Wiring Harness for 2014 Jeep Compass
    Trailers can kill off a wiring harness if they present a short or if the total power demand from all the trailer lights exceeds the harness maximum output current. The folks at U-Haul ought to know the power drawn by their trailers' lighting set-up to prevent the latter problem from occurring. It sounds like they decided to use a hard-wired harness rather than either of the plug-n-play units we offer that are custom-fit for your vehicle. Trailers can have intermittent shorting issues....

  • Is Curt Trailer Wiring Harness for 2017 Jeep Compass Compatible with LED Trailer Lights
    The Curt trailer wiring harness part # C56344 that you referenced for your 2017 Jeep Compass is perfectly compatible with LED trailer lights and would not require any additional adapters or components. I also attached a link to this page that shows all of our LED trailer lights as well.

  • Parts Needed to Tow Trailer with 2016 Jeep Compass
    If you were planning on towing with your 2016 Jeep Compass there are a few items you will need. First let's start with the hitch. For that you would want the # C13081 that you referenced which is a confirmed fit. I attached an install video for this. For trailer wiring you then would want the part # C56344 which is a confirmed fit as well. Since you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise...

  • Turn Signal Shows Hot all the Time with Plug-In Trailer Connector Tester
    If a 4-way trailer connector tester like part # I26 shows that the drivers side turn signal on the Curt T-Connector Vehicle Wiring Harness part # C56344 for your 2014 Jeep Compass is constantly hot then you would first want to remove the driver's side tail light assembly. Once this is done you would then need to remove the connector to the harness and inspect the pins making sure none of them are bent and or corroded. If they are then you will need to clean them up with some electrical...
