  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • Powered Converter
  • CURT

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.

    • Tail lights: 6.0 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 interior trim panels in your rear cargo area. You will have to remove all trunk floor coverings, storage trays, and the scuff panel to access these connection points. 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.


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.

Good kit. Everything was pretty easy other than running the power wire to the trunk but not impossible. Good video online to help with removing panels and installing. I'm happy.

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.




by:

Was pretty easy to install and straightforward instructions.




by:

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.

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.

    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.

  • No Trailer Tail Lights On 2016 Lexus NX 200t With Curt T-Connector Vehicle Wiring Harness
    The 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...

  • Does Trailer Wiring for 2014 Lexus RX 450h Require Trip to Dealer for Reprogramming
    The 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!

  • Comparison Of Curt And Tekonsha Wiring Harnesses For 2017 Lexus NX Turbo
    Both 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.

  • Installation Process for 4-Pole Trailer Wiring Harnesses C56268 and 118652 on 2016 Lexus NX 200t
    For 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...

  • Trailer Wiring Harness Recommendation for 2015 Lexus NX 200t
    For 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.

  • Trouble Locating the Factory Taillight Wiring Harness On a 2016 Lexus NX 200t
    The 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...

  • Trailer Wiring Recommendation for 2018 Lexus NX 300 F Sport
    For 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.
