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 plug on your automobile and the 4-pole connector itself - to help prevent corrosion.

Draw-Tite hidden hitch was very easy to install on 2018 RX450h F-Sport. Just had to remove a plastic underbody panel that covers the area where the hitch is installed. Zero modifications needed. The hitch is a little bit heavy to install by one person but I was able to do so by propping one end up with a cardboard box while getting the other end bolted on. The 2” hitch receiver is a bit tight to get installed the first time, but that will probably ease up over time.
Very pleased with the hitch and feels very solid. Did a road test with bikes loaded and will be taking the e-bikes out for a road trip this weekend.

Hitch and wiring harness installed in less than an hour and half! 2017 RX 350 was equipped with towing package. The converter behind the panel on the rear passenger side. The harness plug was above the end of the exhaust pipe, driver side.

QUALITY PRODUCTS and Quality Company that recognizes Military Veterans with a generous discount!



by:

This is the second harness I have ordered. They work so well and the set up is excellent. I love that they have instruction videos linked to the product. Makes the job that much easier. When I need one in the future I’ll definitely be buying it from from etrailer.



by:

This hitch was very easy to install. I did not have to lower the exhaust. I
just had to pull down a little for the hitch to slip over it. My vehicle was
already prewired from the factory so the wiring was simple plug and play.
One connector just had to remove the factory connector cover and plug it the
harness and route harness along hitch. A couple of long tie wraps, black
electrical tape or any other type of tape would work great for running the
harness along the hitch (not supplied). I am attaching several pictures
after the installation. It looks great and is very well hidden. Receiver is
all that shows with wire connector. There is about 12 to 18 inches of wire
above the facia that can be pulled down for use if needed. Very glad I
ordered the Curt hitch #13541 and T-One wiring Harness for the Factory Tow
package #118252. By the way Great service from ordering over the phone to
delivery.

The hitch on my 2012 and wiring harness are working out great. I even took it to my dealership and they added it to the their records on my vehicle, showing that I added the hitch and harness. They were also impressed with the way I trimed around the hitch, hiding as much as I could. My wife didnt even notice it for a week. This was the first time I used it. Good job with the design and fitment.



by:

Easy and complete instructions to insta ll.



by:

Just installed Draw Tight hitch, wire assembly along with the brackets for a nice look. Everything went smooth with installation and it has a nice clean look as the hitch is well hidden. This is going to work for our bike rack and the cargo carrier I am now going to by. Now I can also get a small utility trailer to pull and haul stuff. I strongly recommend etrailer for all your needs as they communicated with me the whole way through and readily replaced a lock unit that somehow came without the key. Customer service is top notch.

Absolutely Fine!



by:
2017 Lexus RX 450h

The box arrived damaged and part of the hitch was sticking out a good 10" but there was little damage (minor scratches) and all the parts were there. Customer service is second to none and they have been in constant communication with me. I cannot stress how refreshing it is to deal with an online vendor with such a high quality product, integrity and outstanding service. I can't imagine ever ordering from anyone else.

by:
2006 Toyota 4Runner

My 2006 4Runner had a factory installed mounting plate for the trailer wiring hub that was a bit challenging to leverage with this harness. I was able to work though that and make it work though with some zip ties. It would be nice if future versions contemplated those factory mounts.

2020 Toyota Highlander

FITS the new 2020 HIGHLANDER! There is a new connector with the 2020 Highlander redesign under the driver side rear bumper. This cable plugs directly into the Highlander connector. See photo. There is no need to route or run wires for the trailer wiring. You will also need a converter to provide the correct signals to this cable. I recommend using the Toyota Plug-n-play converter part number: PT725-48200. It’s around $60 online. Be aware it is installed behind a panel located next to the driver’s side second row seat. Toyota completely changed the vehicle wiring for the 2020 model year. I also recommend the CURT C99FR hitch. Fits perfectly, easy to install and hides behind the bumper.



by:

I've installed several trailer hitches in the past. The only way this installation would have been any easier would have been the young lady, taking the order, agreeing to come over and do it. I'll install these hitches all day for half what [the vehicle dealer] charges.

The 3 plastic/rubber plugs, on the left side, pop right out and the 2 tow bracket bolts, on the right side of the car, unscrew easily with a 19mm socket. I didn't have anyone to hold up one end of the hitch so I used an upside bucket to hold one end up while putting the two bolts in the other side.

The heat shield never came close to contacting the hitch, so no adjustments were needed.

The wiring harness was also easy to install. There's a pre-wired plug on the left side of the car near the exhaust pipe the harness plugs into. This car was ordered with the towing package so it's my understanding the harness is all that's needed.



by:

I ordered and received a trailer hitch and wiring kit for my 2015 RX350 and also received a very informative video with it. It fit great and is almost invisible and no drilling was necessary. The only issue I had was I was supposed to reuse 2 of the bolts to rehang the exhaust but my bolts were tapered on the end and wouldn't fit so I had to use some generic bolts. But it's still a great product.

2016 Lexus RX 350

I got the trailer hitch the rubber hitch cover and the wiring harness delivered in 5 days from the day that I put my order in, very easy to install nice and tucked underneath the bumper,very well built and very well priced.



by:

Product worked as expected and is high quality.



by:

Was absolutely a plug and play system on a lexus RX350. I did use a marine stainless steel ring clamp to secure the trailer plug side of the holder for my application rather than the recommended installation. Directions were well written.



by:

The wiring plug and harness were an exact match to original specifications for a 19 year old factory install except for turn signals were reversed, this was a minor fix. The final price was OK, but I was disappointed that the website had shown a price of $14.08 less than 12 hours before I placed the order. When I placed the order the following morning the priced jumped to $20.08 plus shipping. After all is said and done, still a great value for the money.

Etrailer,
Very pleased with the service
and feedback on my order of a wiring harness for my 2013 Lexus RX350. Both the customer service and the ordering staff contacted me and indicated that the wiring harness was correct for my vehicle. My order arrived on-time, and the shipping package was in excellent condition. I recommend Etrailer products, relieable customer support, and prompt shipping method.

Quality was excellent

Works as advertised. I installed a pair of these on our new cars in under an hour...the wiring was truly "plug and play!"

    The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118578 is the confirmed fit for the 2017 Toyota RAV4. This custom-fit T-One connector plugs into your Toyota RAV4's wiring harness, which is located inside your trunk, behind the tail lights on both the driver's side and passenger's side.

  • Recommended Trailer Hitch for a 2019 Lexus RX 350
    The trailer hitch I recommend for a 2019 Lexus RX 350 is the Curt Trailer Hitch Receiver part # C13272 which is a fit for all models even the F-Sport. The Curt hitch offers a complete bolt-on installation with no cutting or drilling required. Therefore, the Curt hitch is very easy to install and should only take around thirty minutes or so. The best part of all is that the Curt hitch has a hidden cross tube which you can see in the attached photo and this means that only the receiver tube...

    I recommend picking up the etrailer Trailer Hitch Receive # e22TR for your 2015 Lexus RX 350 because it features a hidden crosstube and a matte black finish so you get a great looking hitch receiver that is going to do a great job at resisting rust and corrosion. If you are planning on using this for towing then you also need the T-One Wiring Kit, part # 118252 if you have the tow package or part # 118255 if you don't, as well as a ball mount kit like the TowSmart Towing Starter Kit #...

  • Troubleshooting Wiring Harness for 2010 Lexus RX 350
    The trailer wiring harness, # 118252, is for a 2010 Lexus RX 350 that came with a factory tow package. It sounds like your RX 350 does not have the factory tow package so you would need to use trailer wiring harness # 118478. If your vehicle is supposed to have the factory tow package (have the dealer run the VIN to determine if it does or does not have the tow package) then the missing components to make it active could be obtained through a dealer.

You will need to push in the locking tab with your thumb and at the same time pull the cap off.

The T-One Vehicle Wiring Harness for Factory Tow Package # 118252 is only designed to replace a damaged factory connector. It is missing the powered convertor.

    The Curt wiring harness # 56083 and the similar Tow Ready # 118252 are intended as replacement parts for the RX 350 that came from the factory with tow package wiring. Since yours does not have a factory hitch this means you will not likely find any connector under the rear bumper/along the frame rail to plug in one of these harnesses, but you can certainly check easily enough.

    According to my Curt representative, there's no record of the existing parking sensors interfering with the installation of the # C13272 Curt Class III hitch or that the parking sensors will interfere with your ability to tow. You'll need the hitch as well as the trailer wiring harness # 118252.

For the RX450h, use # HM11141945 for vehicles equipped with the factory tow package, or # 119250KIT for vehicles without the tow package. For a ball mount, use # C45010 and # 19260 for the 1-7/8 or # 63845 for a 2 inch trailer ball. You'll also need a # PC3 hitch pin. If you click the provided link, you can...

Use a circuit tester such as # PTW2993 to test the connector while someone goes through the lighting functions in the cab of the vehicle. If it has power, then you could use harness # 118252.

To complete your towing setup I also recommend picking up the Tekonsha T-One # 118255 if you don't have the tow package or the T-One # 118252 if you do have the tow package.

For a trailer hitch, I recommend the Draw-Tite Class III Trailer Hitch, # 75676. This trailer hitch has a 4,000 lb towing capacity and a 400 lb tongue weight capacity.

For a trailer hitch I recommend the Curt # C13143 because we have found that they tend to have a stronger construction, and then for wiring you need to start off with the T-One # 118252 for basic trailer lighting.
