Installation

This custom-fit T-One connector plugs into your vehicle's factory tow package wiring harness, which is located just behind the rear bumper. You will have to remove the access cover on your bumper to access this harness.


Once installation is complete, the 4-way flat connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


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.

  • Which Trailer Hitch Receiver and Ball Mount For a 2019 Land Rover Range Rover Sport
    For your 2019 Land Rover Range Rover Sport I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver # 75229 which has a 2x2 receiver and will work with both hybrid and standard models. I included the installation video of the Draw-Tite # 75229 being installed on a 2016 Range Rover Sport and a picture of it installed for you to take a look at. For a ball mount I recommend going with the etrailer Ball Mount Kit # 989900 which includes two ball mounts that offer 3/4 inch rise/2 inch drop,...

  • What Is Needed To Carry Bike Rack W/ Curt Trailer Hitch 13243 On 2018 Land Rover Range Rover Sport
    As long as the Thule bike rack you have is designed for a 2" receiver there is nothing else you will need to install it in the Curt Trailer Hitch # C13243 you were looking at for your 2018 Land Rover Ranger Rover Sport. You mentioned also towing a jet ski trailer, so since you have a ball mount already you just need a vehicle wiring harness # 118681 to allow your vehicle to control your trailer lights. I included a link to the written instructions of the # C13243 and an installation video...

  • Recommendation For Mounting Wire Harness With Connector For 2015 Land Rover Range Rover Sport
    It sounds like you already have a hitch like the Draw-Tite Max-Frame Hitch, Item # 75229, and a vehicle wiring harness like The Tekonsha T-One Wiring Harness, Item # 118681. Going with this assumption, the wiring harness will plug into your OEM package behind your rear bumper. You will have to remove an access cover to get access and you can either store the connector side beneath your hitch under your 2015 Land Rover Range Rover Sport or you can mount it. To mount the connector, you...

  • Recommended Brake Controller For A 2017 Range Rover Sport
    On your 2017 Range Rover Sport, the best option for a brake controller is the Curt Echo # C51180. This will use a factory 7-way or aftermarket 7-way for proper function. If you have a factory 7-way, you can simply plug this brake controller into your trailer connector and you will be ready to go. If you don't have a factory 7-way, you will need to start with a 4-way flat connection. If you don't have one, I recommend the Tekonsha T-One Vehicle Wiring Harness for Factory Tow Package...

  • Will Curt Trailer Hitch for 2019 Land Rover Range Rover Sport Void Warranty/Lease
    The Curt Trailer Hitch Receiver part # C13243 is a great option for a 2019 Land Rover Range Rover Sport and it won't void any warranty. That said, it does require trimming of a plastic under body panel. This may or may not need to be replaced when the lease is up, that would really be between you and the dealer whether they ask you to replace it or not. It won't be very noticeable at all as the panel is on the underside of the vehicle. In regards to the T-One Vehicle Wiring Harness part...

    We have the perfect solutions for you to tow with your 2016 Ranger Rover Sport TD6.

  • Brake Controller Options for 2016 Range Rover Sport HSE
    The trailer company was correct in advising you that with a 2016 Range Rover Sport you would need a wireless brake controller such as the Curt Echo # C51180. This controller works using a factory or aftermarket 7-way, so if you have the factory 7-way you will not need anything else. Should you need to add a 7-way you will first need a 4-flat connection, which you can add with the 4-Pole Flat Trailer Connector # 118681. Then you will want the Installation Kit # ETBC7L to get the necessary...

  • Recommendation between Curt and Draw-Tite Hitches for 2018 Range Rover Sport
    Both the Draw Tite hitch part # 75229 and the Curt part # C13243 are really solid options for your 2018 Land Rover Range Rover Sport and they're both really similar in design but the one difference they have is the brackets toward the front of the vehicle. I slightly like the way the Curt is designed better as it looks like it would carry more weight but even then the Draw Tite is still really solid. So if I were in your shoes I'd buy the Curt. For trailer wiring then you'd want the 4-way...

  • Adding a 4 Way Trailer Wiring Connection to 2015 Land Rover Range Rover Sport
    If your 2015 Land Rover Range Rover Sport has the factory towing package, it will have a small plug somewhere on the rear end that allows you to easily install a 4 way connector for towing. The Tekonsha T-One Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector # 118681 is exactly what you need. If your Range Rover Sport was not equipped with the factory tow package, I recommend using the ZCI Circuit Protected Vehicle Wiring Kit # 119250KIT which will provide you...

  • Trailer Hitch and Wiring Fit for a 2018 Land Rover Range Rover Sport
    We carry two trailer hitch receivers that fit your 2018 Land Rover Range Rover Sport; the Draw-Tite # 75229 and the Curt # C13243. Between the two I recommend the Draw-Tite because Curt requires a strap to be used if you're ever using the hitch for a bike rack or cargo carrier. Since you're going to be towing this may not matter to you. In which case it's pretty much a toss up because both hitches are very similar and both high quality. I've linked the install details to both of them...

  • Will Installation of Trailer Hitch Receiver Void Warranty on 2019 Land Rover Range Rover Sport
    Installation of a hitch like the Curt # C13243 on your 2019 Land Rover Range Rover Sport will not void the warranty. It is not uncommon for a dealer to tell a customer that it will void the warranty. However, consumers are protected under the Magnuson–Moss Warranty Act. This allows aftermarket parts to be installed without warranty issues unless the installation or part caused a problem. The simple act of installing a hitch or other aftermarket part does not void the warranty.
