This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side interior trim panels in your rear cargo area. 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 cargo area.

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.

Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.

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.

Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector - 56061

Average Customer Rating:  4.3 out of 5 stars   (6 Customer Reviews)

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.


I ordered the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector for my Subaru a year ago and it's still going strong. I'm using it to haul a utility trailer that I use for hauling yard waste, lawn mower and snowblower.
Even though this product said it was for my make and model, the tail light converter did not work. I contacted e-trailer and they worked hard to insure they got me the correct one and also updated their website product specs to reflect the correct information. For this reason I am giving them 5 stars.

2011 Subaru Impreza

The wiring is pretty easy and fast to do by yourself if you are handy. One thing I would like to see for this product is a professional instal video on my sedan. They only have a video up for the wagon which has few key features different.


Loved it. Simple enough to install. Follow the layout on the print and you’re good. Pleased


Plug and play. It was super easy!

  • Does the Fuse Holder Wire Loop Need to Be Cut to Install the Fuse Holder
    Yes, you are correct. You will need to cut the loop, strip both ends of the wire and then use the included butt-end connectors to attach the fuse to the Curt Wiring Harness # 56061 and the ring terminal to the positive side of the battery in your 2012 Subaru Impreza Sedan. I would recommend cutting the wire in the middle so that you have equal distance of wire on either side of the fuse.

  • Recommended 4-Pole Trailer Wiring Harness for 2009 Subaru Impreza Sedan
    We do offer a trailer wiring harness for your 2009 Subaru Impreza Sedan, Curt custom-fit harness # 56061. This wiring installs at your taillights with snap-together connectors and requires only one wire, the 12V power wire to the battery, to be spliced. The linked article explains how to route that one wire. The written instructions are linked for you as well. The 4-pole trailer wiring harness you referenced, Tow Ready # 118467, is a fit for several Subaru models including the Forester,...

  • 2015 Subaru Impreza Wagon Trailer Wiring Recommendation
    For the wagon or hatchback models of the 2015 Subaru Impreza for trailer wiring you would want the part # 118573 as the # 56061 only fits the sedan models.

  • Trailer Turn Signals Not Working After Installing Curt Wiring Harness in a 2013 Subaru Impreza
    You can test Curt trailer wiring harness # 56061 on your 2013 Subaru Impreza to determine if the converter is faulty. The first step is to test the wires leading into the converter box from the vehicle using a circuit tester such as # 40376 or a meter if you have one. Have someone sit in the vehicle and go through the lighting functions while testing the input wires on the converter. If everything works as normal on the input side then move on to testing the output side (4-Way end). But...

  • Troubleshooting Curt Trailer Wiring Harness 2013 Hyundai Sante Fe Installed on 2013 Hyundai Santa Fe
    First thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring. That would mean that problem is either due to a ground issue or a short issue. Make sure that the trailer side connector are clean...

  • Troubleshooting Converter Box of Trailer Wiring That Is Not Blinking with Vehicle
    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 # PTW2993 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 see if the current is making it through the converter. If not then the problem is that the converter box has shorted itself out and would need to be replaced. Before you replace it you will want to inspect...

  • Availability of T-1 Connector for 2009 Subaru Impreza Wagon
    Due do differences in the tail light assemblies on the Impreza Wagon, the # 56061 T-1 harness for the sedan will not work with the wagon. For the wagon model, you'd want to use the Curt # C56111 which installs as shown in the linked video. Routing that power wire isn't too difficult, I'll link to an article that explains the process.

  • Recommended Trailer Wiring Harness for a 2009 Subaru Impreza Hatchback
    Trailer wiring harness # 56061 is for Sedan models of the 2009 Subaru Impreza. For your hatchback you can use T-connector harness # C56111. Or you can use hardwire harness # 46255. Considering the T-connector is easier to install and costs less than the hardwire option I would go with it, # C56111. I have linked a video showing how it installs.

  • Trailer Hitch for 2012 Subaru WRX With Receiver That Fits Through Cutout in Bumper Fascia
    When installed, the Curt # C11317 receiver tube would sit right under the bottom edge of the rear bumper fascia. It would not use the cutout in the bumper cover. We do offer a hitch that would install in that manner, though. The EcoHitch # 306-X7279 would indeed install so that the receiver would fit through the cutout you describe. The hitch also includes a magnetic cover that would conceal the receiver opening when the hitch isn't being used. For a trailer wiring harness, you'll want...

  • Flat Tow and Trailer Tow Wiring Recommendations for a 2008 Subaru Impreza
    The wiring kits used for flat towing are designed to receive signals while the wiring for trailer towing is designed for sending signals. The TowDaddy Custom Tail Light Wiring Kit # TD3003 that you referenced would get you halfway there but it actually fits a 2005 - 2010 Chevrolet Cobalt Sedan so you need to use different wiring. For your 2008 Subaru Impreza I recommend using the Tow Ready Tail Light Isolating Diode System # TR118821 for your flat tow wiring and then the Curt # C56111...

  • How to Choose Correct Ball Mount for Towing a Trailer with a 2013 Subaru WRX and EcoHitch
    To choose the correct ball mount/hitch ball combo you simply need to measure the height of the top of the inside of your EcoHitch Invisi Trailer Hitch Receiver # 306-X7279 when it is installed on your 2013 Subaru WRX Sedan as well as from the ground to the bottom of your trailer coupler (while it is level!). You then just need a ball mount with a drop if the receiver is higher or a rise if the trailer coupler is higher. The ball mount kit # 989900 is a great option because it comes with...

The instructions do not exclude models with that light at the bottom center, the hitch receiver should be below the rear fascia once installed.

  • Fascia Trimming Required to Install Curt Class I Part # C11120 on 2011 Subaru Impreza
    The lower bumper fascia would need to be trimmed approximately 1-5/8 inches by 4 inches. You can get a better idea of the necessary trimming by checking the install instructions, and looking at the photo I produced for you. Remember the old woodworkers adage: Measure twice, cut once. If you were planning on using the receiver as a mounting point for a bike rack or cargo carrier, be aware that Curt requires the use of a stabilizing strap like part # 18050. Failure to use a stabilizing...

    If your Impreza is a Hatchback model with single exhaust, the Curt Class I receiver, # C11286 would be a fit. If your Impreza is a Sedan, Draw-Tite and Curt receivers are available. If you were planning on using the receiver only as an attachment point for a hitch accessory like a bike rack, the Draw-Tite # 24807 would be your best choice. The Curt Class I, part # C11284 would also be an option, but if it were to be used for a bike rack or cargo carrier, a stabilizing strap like part #...
