Installation

This custom-fit T-One connector plugs into your vehicle's factory tow package wiring harness, which is located behind the access cover at the center of your rear bumper.


Once installation is complete, the 7-way 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 7-pole connector itself - to help prevent corrosion.

Good value but bracket sent with connector is too small and mount holes do not ine up.


Comments
I recommend using bracket part # A10-9394VP
Mighty Cord Universal 7-Way Mounting Bracket
$7.94
as it will give additional oblong holes for a more universal fit.

Needed hitch to go on vacation quickly they delivered on Tuesday and I ordered it after 4pm Friday so happy with there quick service and all the parts were correct. Hitch was installed by us and had great instructions took about 90 min with the electrical. Thx etrailer for being so prompt..




by:

I ordered 4 items for my 2017 Range Rover Sport SVR. The items came quickly. The box for the hitch came damaged but the hitch was fine and not scratched or bent.
1) Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2" - Item 75229
2) 7 pin wiring harness - Item: 118275
3) 6 and 7-Way Trailer Connector Mounting Box, 3" - Item 18157
4) Reese Trailer Connector Adapter w/ LED Circuit Tester and Dust Cover - 7-Pole to 4-Pole or 5-Pole - Item 78118

I’m relatively inexperienced at working on cars so it took me 3 hours to do the complete install. Was nervous about cutting the bottom plastic panel to accommodate the hitch portion. The instructions were pretty poor but the cutout sizes were shown. Otherwise just watch the video and You’ll be fine.

A few tips:
1) watch the video on their website: very helpful.
2) Much easier if you have an extra hand. The sucker is heavy.
3) On the RRS, put your air suspension at the highest setting so that you don’t have to jack up or ramp your rear wheels.
4) make sure you have a 4.5 inch angle grinder. It was my first time using it but it was easy. you won’t regret it.

Wiring harness clicked in to factory harness perfectly (you’ll find them once you take the panels off). Initially I thought they wouldn’t fit but then I realized the harness ships with the male and female part connected. Once I figured how to pull them apart it all made sense. All the parts were excellent quality and I’m very happy with the result.

NEWS FLASH!!!
This fits 2016-2019 Range
Rover Sport too! Its unfortunate etrailer and manufacturer are unaware of this ever so important info. Hopefully this post will solve your problem. This is a plug and play unit. Now we have lock out of our surge breaks for boat trailer. Forgive the dirt in the photos. This is a 2019, had a 2016 and has same set up.


Comments
At one time, vehicle manufacturers were pretty good about lending vehicles to the hitch and aftermarket wiring companies. Now, especially with upscale brands like BMW, Mercedes-Benz, Range Rover and the like, the vehicle manufacturers arent lending out vehicles like they used to which makes it difficult for the aftermarket suppliers to determine product fits in a timely manner.

  • Mounting Bracket For 7-Pole Connector

  • Trailer Hitch for 2021 Land Rover Range Rover Sport
    For your 2021 Land Rover Range Rover Sport the Curt hitch part # C13243 is a confirmed fit and would work great. It has great towing capacities and is mostly hidden too since only the hitch opening hangs below the rear bumper. If you need trailer wiring too the 7-way kit part # 118275 is a confirmed fit and installs easily.

  • How to Mount 7-Way Connector on a 2015 Land Rover Range Rover Sport with 2" Trailer Hitch
    Thank you for the purchase of the Draw-Tite # 75229 trailer hitch and T-One # 118275 for your 2015 Land Rover Range Rover Sport! We have exactly what you need to mount the 7-Way connector without having to modify anything. If you use the Easy Mount Bracket # C58000 you can secure the 7-Way to the 2" receiver of your trailer hitch (see attached picture). I have attached a sample installation video of this being installed on a 2005 Tucson for you to reference.

  • Recommended Trailer Hitch Receiver and Wiring for 2016 Land Rover Range Rover or Range Rover Sport
    For a 2016 Land Rover Range Rover, there is not an aftermarket trailer hitch option from any of our manufacturers. If they have a 2016 Land Rover Range Rover Sport then I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2" # 75229 and if they have the factory tow package the # 118275. If you don't have the factory tow package then splicing is required and I recommend using the Upgraded Modulite Vehicle Wiring Harness Kit w/ 4-Pole Trailer Connector...

  • 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...

  • What Is The Process To Get My 2020 Land Rover Range Rover Sport Without A Tow Package Ready To Tow
    We have trailer hitch and wiring options for your 2020 Land Rover Range Rover Sport. You will start with the hitch receiver. My hitch receiver recommendation is the Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2", part # 75229. This hitch receiver has a maximum tongue weight of 800 lbs and a maximum gross towing weight of 8,000 lbs. Please keep in mind that you should check your vehicle's owner's manual to see what the maximum gross towing weight and maximum tongue...

  • What Hitch and Wiring do You Recommend for My 2021 Range Rover Sport with a 2021 Flagstaff E-Pro?
    For towing your 2021 Flagstaff E-Pro with your 2021 Range Rover Sport (non-hybrid model), I recommend the Curt - 2" # C13243. Since your E-Pro has a gross trailer weight of about 4,300 pounds and a tongue weight of about 400 pounds, this hitch will provide you the weight capacity you need. It also comes with a gloss outer coating over a base powder coat to give you superior rust and corrosion protection. The hitch is also assembled here in the U.S.A. As far as wiring, since you have...

  • Trailer Hitch Fit for 2020 Land Rover Range Rover Sport Hybrid
    According to Draw-Tite, their # 75229 Class III hitch is a fit for all models of the 2020 Land Rover Range Rover Sport, including the Hybrid. If you'll be using the hitch for towing, you'll need a few other items to complete your towing system. For a trailer wiring harness, use part # 118275 if the vehicle is equipped with the factory tow package or # C59236 without the factory tow package. For a ball mount, use # D-28 with the # PC3 hitch pin and either the # 19260 for a 1-7/8 or # 63845...

  • Trailer Hitch Receiver, Wiring Harness and Brake Controller for a 2016 Land Rover Range Rover Sport
    The T-One Vehicle Wiring Harness # 118275 connects to the factory tow package wiring connector. You will need to verify with Land Rover that your 2016 Range Rover Sport Autobiography has the wiring and connectors from the factory. You will then be able to connect a Redarc Tow-Pro Liberty Brake Controller # RED24FR with their Wiring Harness # RED87FR to your Range Rover. If you do not have the factory tow package you will need the Universal Wiring Harness w/ ModuLite and Brake Controller...
