Features to know about
Installs Without Splicing: Plug-In T-Connector Design
Wiring a trailer can be intimidating, but this harness skips all the tricky stuff. The Curt T-Connector plugs directly into the existing taillight connectors, so there’s no wire cutting or splicing required. Everything fits cleanly behind the lights for a simple plug-and-play setup that’s ready to go once connected.
Protects Vehicle Electronics: Powered Converter Box
This harness uses its own powered converter to draw current directly from the battery through a 12-volt power wire. That means the vehicle’s internal wiring never carries the trailer load. The result is clean, reliable power to your trailer lights while protecting the vehicle’s sensitive electrical system from shorts or overloads.
Delivers Standard Trailer Lighting Functions: 4-Flat Connector
Once installed, the 4-pole flat connector provides all the essential lighting signals—running lights, brake lights, and turn signals—for safe towing. It’s the standard connection used by most small and midsize trailers, so you can hook up and hit the road with confidence that everything works as it should.
Built for Clean and Secure Connections: Weather-Protected Fit
The connectors snap tightly into place at the tail light housings to ensure solid contact. When everything is plugged in properly, you get consistent signals without flicker or lost connections. It’s a durable setup that keeps out moisture and road grime for dependable performance every time you tow.

excellent packaging, good description of installation, and very well made. Fit is not perfect for 2018 NX. Back of mount forces tailpipe to contact hitch. This caused a very load vibration in the vehicle. I modified hitch by removing some "extra" material so that exhaust could hang free. See pic. Also, wear gloves! I had a wrench slip and had my hand get cut on sharp decorative exhaust tips.

I'm so grateful for the help and expertise I received from the folks at etrailer, and for the great quality products. My wife and I will be driving across the country as part of a move and we needed to be able to pull a trailer behind our small SUV. Justin at etrailer figured out exactly what we needed in a single, simple phone call and all the materials were at my door in just a couple days. A service station down the street helped with installation and we are good to go. (And my hitch also works with my bike rack!) A truly excellent experience.

Tricky installation due to number of panels that need to be removed, but once that part is figured out the product goes in easy. If removing interior panels gives you ulcers this might not be for you. The instructions don't really tell you how to remove the panels although they do indicate where any fasteners that need removal are. Once the fasteners are out it's a matter of pulling and hoping. The final side panels where the connectors are located do not need to be removed all the way to access the connectors. Four stars only because the instructions could be more precise.

- Installation Process for 4-Pole Trailer Wiring Harnesses C56268 and 118652 on 2016 Lexus NX 200tFor the 2016 Lexus NX 200t F-Sport both of the aftermarket 4-pole wiring harness kits we offer, Curt # C56268 and Tekonsha # 118652, use a separate 12V power wire that will be run to the battery and connect through an included fuse holder. This separate power connection delivers the actual current to operate trailer lights, bypassing the vehicles internal wiring. This isolates the car's wiring from any potential damage from short-circuits on the trailer. Apart from this one power wire...
view full answer... - Trouble Locating the Factory Taillight Wiring Harness On a 2016 Lexus NX 200tThe T-One Vehicle Wiring Harness part # 118652 is a confirmed fit for your 2016 Lexus NX 200t. This harness actually installs inline with the factory taillight wiring harness so there will not be any sort of unused plug if that was what you were looking for. In order to access the factory taillight wiring harness you need to remove a few trim panels. I have then attached a photo that shows where the factory taillight wiring harness is located. Unfortunately, we have not yet had the chance...

- Curt Trailer Wiring Harness that Fits 2018 Lexus NX 300 Actually we do list the Curt trailer wiring part # C56268 as a confirmed fit for the 2018 Lexus NX 300 now. You may have bought this before the fit was updated but currently we have this as a fit for the 2018 model.
view full answer... - Recommended Hitch for a 2020 Lexus NX 300hI would be happy to help you. To add a hitch to your 2020 Lexus NX 300h, I recommend the Curt Trailer Hitch item # C13337. This hitch is custom fit for the NX 300h models and bolts to your Lexus with included hardware. This is a class III hitch with a 2" receiver. It has a 3,500 lbs towing capacity and a 525 lbs maximum tongue weight. We had a NX 300h in the shop awhile back and I have attached a couple of pictures and linked the installation video we made putting the Curt item # C13337...

- Comparison Of Curt And Tekonsha Wiring Harnesses For 2017 Lexus NX TurboBoth the Curt # C56268 and T-One # 118652 wiring harness are designed to work with your 2017 Lexus NX Turbo. The difference between the two harnesses is that the T-One maximum amperage draw is 2.1 amps for stop/turn lights and 7.5 amps for tail lights. For the Curt harness the maximum amperage draw is 3.0 for stop/turn lights and 6.0 for tail lights.

I did grab a couple of images from the install details that I've attached. The install details are attached as well. This hitch is confirmed to fit your Lexus. If you're going to be towing you'll also need trailer wiring. The Curt Wiring Harness # C56268 will provide you with a 4-way trailer connector. This will power a trailer's running, brake, and...
view full answer... - Trailer Wiring Harness Recommendation for 2015 Lexus NX 200tFor your 2015 Lexus NX 200t the Tow Ready harness part # 118652 is a confirmed fit. There actually aren't any install videos for this specific harness so you may be thinking of the # C56268 which is also a fit for your vehicle and does have a review video which I linked. The converter boxes do look different. The Tow Ready would be the kit I would recommend though as we have the best luck in terms of reliability with this brand.
view full answer... - Trailer Wiring Recommendation for 2018 Lexus NX 300 F SportFor your 2018 Lexus NX300 F-Sport we have universal trailer wiring kits like the ZCI part # 119250KIT which will work well, but at this time (August 2018) we don't have any custom fit options. As far as universal wiring goes though the ZCI is the best option as it doesn't require any splicing. It instead uses sensors to tap into the trailer wiring.
view full answer... - Does Trailer Wiring for 2014 Lexus RX 450h Require Trip to Dealer for ReprogrammingThe trailer wiring kits we offer for your 2014 Lexus RX 450h like the Tekonsha part # 118255 do not require a trip to a dealer to reprogram anything. This installs really easily and you're on your way!
view full answer... - Does Curt Trailer Wiring Harness Fit 2020 Lexus NX 300Yes, the Curt trailer wiring harness part # C56268 that you referenced is a confirmed fit for your 2020 Lexus NX 300 F Sport front wheel drive.

view full answer... - Troubleshooting Turn Signals and Running Lights Not Working Curt C56268It's probably just a matter of unplugging the connectors and plugging them back in as it sounds like some of the pins aren't making contact. If that doesn't fix the issue I would assume the converter box is bad and would need to be replaced.
view full answer... - No Trailer Tail Lights On 2016 Lexus NX 200t With Curt T-Connector Vehicle Wiring HarnessThe correct Curt T-Connector Vehicle Wiring Harness for a 2016 Lexus NX 200t (F-Sport Included) is part # C56268 so we first need to confirm this is what you have. Once this is done we then need to confirm the vehicle's running lights are working correctly. If so then test the brown wire with a circuit tester before it enters the converter box while the signal is active. If you don't have power here then there is an issue with the vehicle's wiring so make sure you have the pigtail ran to...
view full answer... - Which Trailer Hitch Receiver Fits a 2016 Lexus 200t SUV? The Curt Trailer Hitch Receiver # C11389 you found fits the 2016 Lexus IS 200t sedan. I believe you are looking for the either the Curt 1-1/4" # C12143 or 2" # C13337 receiver which fits a 2016 Lexus NX 200t as this is the only 200 version SUV I see Lexus made in 2016. Please let me know if you are looking for something different or a different vehicle entirely. If the NX 200t is the correct vehicle the 4-Way # C56268 will allow you to connect to the lights on most small trailers you...

Yes, the Draw-Tite Max-Frame Trailer Hitch Receiver # 75956 and Swagman XTC2 TILT Bike Rack # S64671 are compatible and good options for your 2015 Lexus NX 200t. Do note this bike rack is only capable of hauling 2 bikes up to 35lbs each with a maximum tire width of 2-1/2". If you have the wider tires on your mountain bike you will need the larger Hoops # S64674 for each bike to fit fat tires up to 5" wide.

If there will be any interference, it'll be right where the receiver tube is located. If you try waving your foot in the area a few inches right of left of the receiver opening, the sensors will pick up the movement of your foot and the hatch will open for you. Then for a wiring harness you'll need the Curt T-Connector Vehicle Wiring Harness with 4-Pole...
