Features to know about

Installs Fast with Plug-and-Play Connectors: Inline Tail Light Connection

Wiring for towing doesn’t have to mean cutting into factory wires. This Curt T-Connector plugs inline with the tail light connectors to give you a 4-pole flat trailer connector. It’s a mostly plug-in setup that keeps the job clean and simple, so you can get your trailer lights working without rewiring your vehicle.

Protects Your Factory Wiring: Powered Converter Module

The included powered converter routes the trailer lighting power through a dedicated 12V wire that runs to the vehicle battery. This design keeps the trailer load off the factory circuits so your car’s wiring stays safe from overloads or shorts. Even if the module loses power, your vehicle lights continue to work normally.

Keeps Trailer Lights Reliable: 12V Hot Lead for Steady Current

The harness uses a 12V hot lead that supplies direct power for the trailer lights. This helps ensure consistent brightness and dependable turn, brake, and running light signals even on longer wiring runs or with multiple lamps. It’s the same circuit used in testing by Curt for stable performance.

Clean Install Using Existing Grommets: Factory-Style Routing

Running the black power wire is straightforward thanks to existing grommets and factory channels under the car. You can route it cleanly up the firewall and along existing wiring, securing it with zip ties and finishing with a fuse near the battery for easy access. The end result is a tidy install that looks built-in.

Ready for Everyday Towing: Standard 4-Flat Output

Once installed, you get a standard 4-flat connector that powers running lights, turn signals, and brake lights on most small and medium trailers. It’s durable and convenient for quick plug-ins whenever you’re ready to tow.

Received the package on time, and install was very simple.



by:

This product was easy to install while the car was on a lift as I opted to run the power wire on the outside of the vehicle. It worked great right from the start and did not interfere with tail light functionality. Overall a great product.



by:

Took about twice as long to install than the hitch but mainly because I took my time. The trunk part of the installation was really quick and everything fit great! The tricky part was the run up to the battery for power - this was daunting until I watched the etrailer video and saw how they ran the wire under the car, not through the interior. Once I figured this out the install only took about 2 hours (again, I was in no hurry and was very cautious). I used a fish tape to run the wire through the channel and up the fire wall for the everything ahead of the rear wheels. Great product and advice, thanks!



by:

I haven’t installed it yet. But,
It looks
comprehensive and if it’s as easy to install as the trailer hitch, this will be a piece of cake.



by:

Great customer service and on time delivery. Harness work perfectly and was a breeze to install. Made a mistake of ordering the harness from a national auto parts distributer on April 4th and it wasn't shipped until April 12th and I still can't track it. Ordered the trailer hitch from another national auto parts distributer and when I got it it was damaged. My advise to anyone is if you need to purchase any trailer related gear get it form it form a company that knows what they are doing like etrailer.

  • Is There a Trailer Hitch Receiver Available For a 2020 Volvo S60?
    While I do not see any aftermarket manufacturers with a trailer hitch receiver for your 2020 Volvo S60, you may still be able to have one fabricated at a nearby fabrication shop. The Weld-On Receiver # E17 may help them to create a custom hitch on your Volvo. I recommend also installing the Curt T-Connector Vehicle Wiring Harness # C56224 when you have the receiver fabricated. This will give you a 4-flat connector which connects to most small trailers. It will also allow for Auxiliary...

  • Troubleshooting Curt Vehicle Wiring Harness Causing Vehicle Turn Signals To Not Function.
    It sounds as if one of the pins is either damaged on a connector or in the wrong place from the factory on the Curt T-Connector Vehicle Wiring Harness # C56224. First check the connectors on the Curt harness for any pins or receptacles that appear to be bent, broken, pushed out of their socket or damaged in any way. The only way to determine if one of the wires is installed in the wrong location is to trace the wires on the Curt harness. Since most of the wires used on the right side...

  • Trailer Wiring Harness For A 2020 Volvo S60 T5 Momentum
    Hey Charles, The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56224 is listed as a fit for the 2020 Volvo S60 by Curt so that makes me wonder if you possibly got the wrong wire harness or if you're just trying to plug into the wrong connectors. Curt usually has their part numbers on the packaging and the on the paper instructions. If you do have the # C56224 then send me some pictures of your tail light connectors.

  • Curt Trailer Wiring Harness Hot Lead Wire Installation On 2014 Volvo S60
    To run the hot lead wire to your battery from the trunk, I recommend running the wire under the car versus inside the cabin of your vehicle and then back out. You will use existing grommets where available and then follow other wires through the channel up the firewall and to your battery. I recommend using zip ties to secure the wire as needed. I recommend using the fuse near the battery for easy access. I've attached an article to help.

  • Will The Draw-Tite Trailer Hitch Receiver # 75916 Fit a 2017 Volvo S60 Cross Country?
    Jenny, I can confirm the Draw-Tite Max-Frame Trailer Hitch Receiver # 75916 will fit on your 2017 Volvo S60 Cross Country. While Matt did not get the receiver from us we do have several reviews verifying the fitment without any issues. I recommend installing the Curt T-Connector Vehicle Wiring Harness # C56224 when you install the receiver. This will give you the common 4-way flat connector used on most small trailers and with Auxiliary Lights # C53201.

  • Carrying a 231 Pound Motorcycle on a 2014 Volvo S60 with 165 Tongue Weight Capacity
    Tongue weight is the downward force put on a hitch by whatever it is carrying. When you're using a hitch for a carrier, like the cargo carrier you're getting or a bike rack, all of the weight on the hitch is tongue weight. The etrailer Motorcycle Carrier, part # e98873, weighs about 58 pounds itself. So between it and the 231 pound motorcycle combined the tongue weight you're trying to carry is about 289 pounds. If your Volvo has a 165 pound maximum tongue weight then you're way over...

  • Can the Curt T-Connector be Connected to 12V Outlet for Installation on a 2016 Volvo S60
    The whole purpose of the black module box and running the power from the battery on your 2016 Volvo S60 for the Curt T-Connector # C56224 is to bypass the wiring on your vehicle so that your trailer won't overload your factory wiring and that if anything happens to your trailer wiring your vehicle wiring is protected. If you were to connect the black power wire to a 12V outlet on your S60 then there is a possibility that your vehicle wiring won't be protected. We always recommend installing...

  • Is There a Custom Fit Trailer Hitch Receiver For a 2019 Volvo S60 T5 Inscription?
    It appears you will need to have a custom receiver fabricated for your 2019 Volvo S60 T5 Inscription. We have the 1-1/4" # E-911 or 2" # E-9 receiver tube that you can use to have a receiver fabricated. Currently none of our aftermarket manufacturers are producing a receiver for your Volvo. I was able to verify with Curt that their T-Connector Vehicle Wiring Harness # C56224 will fit your Volvo and give you a 4-way flat connector. This will connect to the tail lights on most small trailers...

  • Replacement Wiring Harness for a 2013 Volvo S60
    Sounds like you blew out the converter on the Hopkins item # HM11143720. These converter's are extremely sensitive to faults and surges from trailer wiring and tend to do crazy things when they are damaged. They don't offer a replacement part for this so I am sorry to say you will have to go with a completely new wiring harness. The Hopkins item # HM11143720 harness is still available and it looks like you got quite a few years out of yours. You can chose to replace it with the same part...
