Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located in your rear cargo area. You will have to remove the threshold cover, cargo trays, and some interior paneling to access this 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 your rear 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.


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 multiplex-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.

Item was easy to install, although instructions could have had better pictures. Kit was missing a fuse, which the instructions said was included. Other than that, order received faster than I expected. Would order from you again.

Ask the Experts about this Tekonsha Custom Fit Vehicle Wiring

  • Recommended Trailer Hitch Fit for 2017 Nissan Rogue
    The trim levels of the 2017 Nissan Rogue won't have any bearing on the hitch fits, but the hitch you need will depend on whether you have the Rogue or the Rogue Sport which are distinct models that have different hitch fits. If you have the Rogue, I'd recommend the etrailer brand Class III hitch, part # e98846. If you'll be towing with the hitch, you'll also need the # 118480 wiring harness, the # 2753 ball mount and # 19261 for a 1-7/8 inch ball or # 63845 for a 2 inch. If you have...

  • Trailer Hitch and Wiring Recommendation For 2017 Nissan Rogue Sport
    There are two hitch options for the 2017 Nissan Rogue Sport, Curt Class III 2" hitch part # C13377 and Draw-Tite Class III 2" hitch part # 76177 which are almost exactly the same. The installation, weight capacity and concealed cross tube design are the same for both hitches. The only real difference is that the Curt option is assembled in the USA which is why I recommend it. I have attached an installation video for your reference. If you need wiring, I recommend Tekonsha T-One Vehicle...

  • Why Hitch is Made for 2019 Nissan Rogue Sport When Nissan Says No Towing
    This is a really good question, but the short answer is that if there's a demand for a hitch for a vehicle our manufacturers are going to make one regardless of what the owners manual states. Some people will chose to tow with the hitch while a lot of others will carry only a bike rack or cargo carrier in the hitch. For your 2019 Rogue Sport the hitch I recommend is the Draw Tite part # 76177 which is a Class III, 2 inch hitch with plenty of capacity and also only has the hitch opening...

  • Where Does a Draw-Tite Trailer Hitch Mount on a 2017 Nissan Rogue Sport
    When installing Draw-Tite trailer hitch # 76177 on your 2017 Nissan Rogue Sport you will use the included hardware on the driver's side. There are 2 bolts and 2 blocks that will get fed into the frame. The threaded ends will exit through 2 of the holes in your picture, through the holes in the hitch, and secured with washers and nuts. If you plan on doing some towing I recommend etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and...

  • Trailer Hitch Recevier Fit for 2019 Nissan Rogue Sport
    There are trailer hitch receivers which fit your 2019 Nissan Rogue Sport, though not the one you mentioned, as that is a fit for standard Nissan Rogues. Instead, the trailer hitch that fits your '19 Rogue Sport is one of the following: - Curt Trailer Hitch Receiver # C13377 - Draw-Tite Trailer Hitch Receiver # 76177 These hitches are identical in terms of installation, bumper clearance, and ground clearance so I recommend you go for the one with the best price point, as both will...

  • Why is Trailer Hitch Made 2018 Nissan Rogue Sport if Owners Manual Says No Towing
    The short answer is that if there's a demand for a trailer hitch for a new vehicle our hitch manufacturers will make one. We have to recommend you stick with any guidelines listed in the owners manual for the vehicle but some people are still going to tow with the vehicle or others may install a bike rack into the hitch. The Draw Tite hitch part # 76177 is a great hitch confirmed as a fit for your 2018 Nissan Rogue Sport. Only the hitch opening hangs below the rear bumper which means...

  • Trailer Hitch for 2019 Rogue Sport
    The Draw-Tite Class III hitch you mentioned, part # 76177 is a fit for your 2019 Nissan Rogue Sport. Draw-Tite estimates that an experienced installer should be able to complete the install in about an hour. Any trusted mechanic should be able to handle the installation with no problem. What you'll pay for the installation will depend on the going rate for hourly ship labor in your area. I've linked you to some installation videos that I hope you'll find helpful.
