  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat

Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located inside your trunk, behind the tail lights on both the driver's side and passenger's side. You will need to remove some interior trim or carpeting to access the 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 and insert the provided fuse.


Once installation is complete, the 4-way flat 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.


ModuLite Powered Tail Light Converter

A ModuLite power module is built into this T-One connector. 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 your trailer. This power module functions as a tail light converter to combine 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.


With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Hitch slider as expected, wiring was a breeze. I opted to keep the main powered wire external rather than muck around with it but plug and play and the lights are spot on, no splicing so I can return it to factory if needed for some reason. Hands down the easiest trailer wire I have installed and customer service that should be used as a benchmark for the digital world.

I have yet to receive the wiring harness so I am unable to rate the wiring harness at this time.


Comments
I see that you have also received a hitch receiver. We like to keep all of the items in the same box. Can you please check the box holding your hitch to make sure that the wiring harness is not also in there?

My mistake, I received the light kit inside the box that the trailer kit came in.

  • Recommended Trailer Hitch and Wiring for 2017 Nissan Sentra
    For your 2017 Nissan Sentra, I recommend the Draw-Tite Class I Sport Frame Receiver Hitch # 24907. This Class I hitch is confirmed to fit your vehicle as long as you do not have the SR model. I recommend this over the Curt alternative because unlike Curt, Draw-Tite does not require you to use additional stabilizing straps for non-trailer loads, such as bike racks and cargo carriers. We have not yet had a chance to install this on your 2017 Nissan Sentra, so we do not currently have a...

  • Comparing Curt and Tow Ready Trailer Wiring Harnesses for a 2014 Nissan Versa Note SL
    Like you mentioned, the Curt trailer wiring harness # C56206 for the 2014 Nissan Versa Note does not require a direct connection to the vehicle battery whereas Tow Ready harness # 118582 does. At the back of the vehicle the installation of the harnesses will be the same. The only difference is that power wire on the Tow Ready harness. That power wire is what will power the trailer lights. With the Curt harness the trailer lights will be drawing on the vehicle tail light wiring. Modern...

  • Trailer Wiring Recommendation for a 2015 Nissan Versa Note
    I have a solution for you, but the # HM11143704 only fits the sedan models of the 2015 Nissan Versa. What you have is the 2015 Nissan Versa Note so you would instead need the # 118582 which has the square connectors you described.

  • Will the Draw-Tite DT48MR Hitch Fit a 2021 Nissan Sentra SR
    The Draw-Tite # DT48MR will indeed fit your 2021 Nissan Sentra SR, and actually the SV models as well. Though there will be drilling required for the installation, as with all hitches for your vehicle, the included instructions will lay out what needs to be done in detail. If you were planning on towing with your Sentra SR, I recommend also installing the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat # 118582. This is mostly a plug and play harness, but you will need to run one...

  • Recommended Trailer Hitch for a 2014 Nissan Versa Note
    I recommend the Draw-Tite I hitch # 24909 as the towing capacity is 2,000 pounds and will have a maximum tongue weight of 200 pounds. It's corrosion resistant and the fully welded steel construction ensures great strength and durability. A pin and clip is included with this Draw-Tite hitch # 24909 and if you plan on doing any light duty towing, I recommend the ball mount # 3592, 2-inch hitch ball # 19258 or 1-7/8 hitch ball # 19256 and wiring by Tow Ready # 118582. I would double check...

  • Will Draw Tite Hitch 24909 Fit a 2014 Nissan Versa Note S
    Draw-Tite trailer hitch # 24909 is listed as a fit for all models of the 2014 Nissan Versa Note so that means it would also fit the Versa Note S. For trailer wiring you would then want the part # 118582 which is also a confirmed fit. For a ball mount you would want the part # 3592. For a 2 inch ball you would want the part # 19258 or for 1-7/8 inch ball part # 19256.

  • Height of Curt Trailer Hitch C11349 For 2016 Nissan Sentra
    Definitely can help you out here and the height from the ground to the top of the receiver on your 2016 Nissan Sentra will be approximately 10 inches for the Curt hitch you asked about, which is the following part number: - Curt Trailer Hitch Receiver # C11349 The actual height should be very close to that once you install the hitch, but could vary based on a number of factors, like tire pressure or size, etc. So I do recommend installing the hitch first and measuring it and the coupler...

  • Parts Needed to Tow Motorcycle Trailer with 2017 Nissan Sentra
    I have a solution for you, but the Curt # 13555 is designed to fit on mid 2000s Honda CR-V's and not the 2017 Nissan Sentra, so you wouldn't be able to use that hitch. Instead, I recommend using the Curt # C11349 which is a confirmed fit on your vehicle. The Curt hitches tend to have a more durable powder coating on them to some of the other available hitches so it will hold up much better to rust and corrosion. In order to tow with your 2017 Nissan Sentra you will also need a wiring...

  • Will the Draw-Tite Sportframe # 24794 Fit a 2018 Nissan Sentra
    We do have a trailer hitch that is confirmed as a fit for your 2018 Nissan Sentra but the Draw-Tite Sportframe # 24794 only fits Nissan Sentra models from 2007-2012. For your 2018 you need the Draw-Tite Sportframe # 24907 instead. You will also need wiring # 118582, a draw bar like part # 3593, and a hitch ball like 1-7/8" part # 19256 or 2" part # 19258. Be sure to follow any instructions in your owner's manual regarding towing with your vehicle.

  • Trailer Hitch Receiver and Wiring Harness For a 2022 Nissan Sentra SR Trim
    The Draw-Tite Sportframe Trailer Hitch Receiver # DT48MR is confirmed to fit your 2022 Nissan Sentra SR. The S is the only trim level of your Sentra that the receiver will not fit. Draw-Tite recommends using their Drawbar # 3593 in the rise position with either a 1-7/8" Ball # 19256 or 2" Ball # 19258 to match your coupler. I recommend adding the T-One Vehicle Wiring Harness # 118582 when you install the receiver. This will allow you to connect to small trailers with a 4-way flat connector...

  • Highest Capacity Trailer Hitch Receiver for 2017 Nissan Sentra
    The highest capacity trailer hitch receiver for a 2017 Nissan Sentra is 2,000 lbs towing and 200 lbs tongue weight (please keep in mind there are no fits for a Sentra SR) the Draw-Tite Trailer Hitch Receiver # 24907 and Curt Trailer Hitch Receiver # C11349. You mentioned 103 kg (227 lbs) and neither of these hitches will be able to utilize a motorcycle and carrier with that much weight, and there isn't a hitch available for your Sentra that will allow you to use a carrier. The only option...

  • Trailer Hitch That Fits 2013 Nissan Sentra SV
    Yes, the Curt Trailer Hitch # C11349 is absolutely compatible and will fit your 2013 Nissan Sentra SV. This is a Class I hitch with a 1-1/4 inch receiver and is a complete bolt-on installation, which is great for your car because it does not require any drilling to install. For wiring which will give you a 4-way connector and allow you to power your trailer's lights you need Wiring Harness # 118582. The correct ball mount for this trailer hitch is the Curt # C45521 which requires Pin...
