  • Trailer Hitch Wiring
  • No Converter
  • CURT

Quickly and easily install a 4-way trailer connector on your Lexus RX 450h with this custom harness. Connector plugs directly into OEM tow package port - no cutting, splicing or tapping required.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Designed for use with a factory tow package
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection point behind rear bumper
    • Plug in connector

Installation

This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located behind the rear bumper, along the driver's-side frame rail.


Once installation is complete, the 4-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 plug on your automobile and the 4-pole connector itself - to help prevent corrosion.

The wiring worked out great! It was an exact fit for my car. This is really a great website with plenty of technical information for making a buying decision and plenty of videos to help support the installation process. After a year of you something zero problems.

When it comes to quick, slick, and easy DIY relative to a trailer hitch wiring harness for trailer lights, this puppy is the ticket! I am not a very technically adept individual and so having the simplicity that this plug-and-play harness offers is HUGE!



by:

Took my local independent garage only 45~ minutes to Completely install and wire. The 6" cut of the underneath plastic is about 8"-12" depending on car FYI. Good assistance via phone and a perfect recommendation. Nice quality hitch! Wiring is plug and play!



by:

Worked great. Connected right up to the OEM plug for easy install. Perfect length to run to hitch receiver



by:
2015 Lexus RX 350

Shipping was prompt and extremely well packaged. I received timely updates on the progress of my order (which was much appreciated as I needed this an upcoming trip). Both the recommended hitch and wiring harness were a perfect fit. The installation video and PDF were informative and accurate, making the installation stress free and within the estimated timeframe. One hint: if working alone, a floor jack to support the hitch works as well as another set of hands.

This was my second order from E-trailer. Their products and support are excellent.

Literally cannot get simpler to install than this. Luckily, my 2010 Lexus Rx450H was set up with the factory tow package (and luckily I kept the window sticker to verify that!), so once the trim panel below the bumper is removed, the electrical connection is on the driver's side frame rail, capped. Remove cap, plug in the wiring harness, zip tie to the cross bar of the hitch, you're done. Shipping was super fast--ordered on Wednesday 6-14-17, scheduled for arrival 6-19-17, arrived late morning 6-17-17. Thank you!

I'm using it to tow troop equipment and canoe trailers for my son's Boy Scout events.



by:
2015 Lexus RX 350

As easy as all the reviews said it would be. Took a little while to get new bolts started that replaced OE self-tapping bolts. But it all lined up and gave a professional finished look when completed. Now I'm ready to help my friend install the hitch on his wife's RX. Won't hesitate to recommend etrailer.com to all in the future.



by:

Great product, excellent support. Very easy install in 25 minutes. Install directions very good. Holes are slotted in hitch, would recommend starting all bolts leaving bolts loose, then center hitch by bumping with wooden block before tightening. Then torque to spec.



by:
2013 Lexus RX 350

Super easy to install especially if you have the tow prep package on your car. The bracket makes the look more professional.



by:

Very happy with my etrailer purchase. The dealership wanted to charge $1,700.00 to install my hitch. Etrailer saved me significantly without any hassles. I was able to purchase and have my mechanic install a hitch for 1/3 of the dealership cost.



by:

Fits perfectly ... installed in less than an hour with a second set of hands from my son. And the genesis that snapped right in to the prewired rx350 tow wiring package .... all at 1/3 of the price the Lexus dealer was going to charge !!



by:

This was an easy installation. My Lexus has the built in towing package.



by:
2013 Lexus RX 350

All I can say is, thanks etrailer for having the right product for the Job!! Product as advertised! Installation was a breeze taking only 45 minutes. I did the installation without raising the vehicle up off the ground. As a side note, the Lexus dealer wanted over $700 for doing the same job, no surprise there..



by:

Easy to install with on line videos to assist you. Very affordable compared to the car dealership

The shipping was a little slow. All my other packages came 2 days earlier.



by:
2021 Lexus RX 350

WOW. Fast shipping and packaged well. Great video to assist if needed. I made a call to verify that it fit my car. Very quick phone pick-up. Very pleasant and helpful.
The hitch is barely noticeable.
I give this place a 10.

The trailer hitch is an excellent product, well made & easy to install. I give it a 5 star rating. The wiring harness also was good quality
and worked well.



by:
2017 Lexus RX 350

The video combined with actual product made this install easy. The connector was exactly where it should be, it plugged in and with the 5 ties, it went snuggly into place.

Excellent product. really east to use



by:

Hitch fit perfectly and instructions were clear. It would be nice if there were a method for stowing the wiring harness connector out of sight.



by:
2019 Lexus RX 350

you guys did a great job. you got me exactly what i asked for and got it out quick. the trailer hitch is actually much better than i was expecting. it is very heavy duty and mounts to the vehicle with 6 bolts instead of just 4 bolts like other manufacturers hitches do. i can't wait to install it and tow something lol. once again thanks for the great job and nice product



by:
2018 Lexus RX 350

Fit perfectly on our Lexus RX 350 and there was plenty of length to allow you to route the wiring harness any way you choose. The video series etrailer puts together on how to install the time is wonderful and very helpful, especially for those who learn by watching someone do the install first.



by:

The product is probably fine but I needed an electronic converter for my vehicle since it didn't have the trailer wiring from the factory. This was not clear from the eTrailer description.

When entering the year, make, and model of the vehicle and then ing trailer wiring harness there is a down menu asking if the vehicle has a factory tow package or does not have one. For a 2015 Lexus RX 450h without a factory tow package you will want part # 118255.

  • Can The Bumper Fascia On a 2022 Lexus RX 350 Be Trimmed With a Razor Blade?
    It is very difficult and dangerous to try to trim the fascia on your 2022 Lexus RX 350 using a razor blade when you install the Draw-Tite Max-Frame Trailer Hitch Receiver # 75540. Since you have to trim the rear fascia as well as a couple panels under your Lexus to install the receiver you have a couple options. First you can take your Lexus to a service center before you install the receiver to have the panels trimmed per the manufacturer instructions that are linked below. You can also...

    The Draw-Tite Max-Frame Trailer Hitch Receiver # 75540 has been successfully installed on other 2022 Lexus RX 350 F-Sports with the kick sensor for the rear lift gate. Do note that the receiver tube will limit the range and function of the kick sensor and you may no longer be able to use the function.

  • Recommended Hitch for a 2022 Lexus RX 350
    Yes, we do have a trailer hitch for your 2022 Lexus RX 350. It is the Hidden Hitch by Draw-Tite item # DT58GR. This hitch is custom fit and bolts directly to your Lexus with included hardware. The reason I like this hitch is that the 2" x 2" receiver is completely removable. When you're not towing or using an accessory you won't be able to tell your Lexus has a hitch. The crosstube attaches behind the rear bumper and the receiver attaches behind the bumper as well. To tow with this hitch...

  • Trailer Wiring for 2020 Lexus RX350 That Doesn't have OEM Tow Package
    Hey Shane, for your 2020 Lexus RX 350 that didn't have a factory hitch the trailer wiring that you honestly should have gone with is the part # C56217 which is for the versions of the vehicle that don't have the tow package. While your vehicle has the connector it's not active which is why it's not working as-is. Maybe Lexus dealer could activate the wiring harness but we don't have any info on that.

I have linked an installation video below so you can see how to get it set up. If you are planning on towing you will also need a wiring harness item # 56083 for the Lexus's with the factory tow package or item # 119250KIT for the vehicle's without the tow package and a ball mount kit item # C45534.

What you saw came from before the hitch had been tested and confirmed to fit on your vehicle. If you plan on doing some towing, you will also want the # 56083 for wiring.

    Yes, we do! The Hidden Hitch by Draw-Tite Hitch item # DT58GR you were looking at actually fits both the F-Sport and standard model of the 2021 Lexus RX 350. This hitch is custom fit and bolts to your Lexus with included hardware. I really like this hitch because the 2" receiver is detachable and the crossbar installs behind your rear bumper.

    When using the Tow Ready Mounting Bracket # 18144 to mount the 4-way trailer connector from the Curt T-Connector Vehicle Wiring Harness # 56083, you should not have to cut the harness in any way. After installing the mounting bracket, you will simply route the 4-way through the bracket opening and input the cap on the end of the connector. The opening on the bracket is 1-3/8 inches in length horizontally. You can use the bracket along with the short bracket # 18140 for a no drill application....

Instead, you're going to want to use the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56217, as # 56083 was designed to be used with vehicles that have the factory towing package.

The other possibility is that the plug that you found on your 2010 Lexus RX350 still has the protective cover on the plug.

The 10 pin connector should be located on the passenger side just below the taillight. The 4 pin connector will be underneath the drivers side bumper cover. It may require you to use the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package # 56083 to make that connection. The video that I linked below will help you find the 4-pin connector.

    All of the hitches available for your 2013 Lexus RX 350 are pretty similar. The biggest difference is that the Curt Hitch part # C13143 can fit the F Sport and non-F Sport models. Because of that I would recommend the Curt hitch. The trailer wiring available for your vehicle, part # 56083, is only available for the models of the vehicle that have the factory tow package. Without the factory tow package use # 118255. I attached videos for you to check out as well.

    The Curt T-Connector Vehicle Wiring Harness for Factory Tow Package # 56083 requires your 2021 Lexus RX 350 to have the factory tow package which includes a factory installed module to power the trailer lights.

    I'm assuming you have a 2013 Lexus RX350. Did the # 56083 wiring harness ever work, or did it work for awhile and then stop? From my research, the connector should work once plugged into the factory towing connector under the vehicle, unless your vehicle isn't equipped with the tow package. If the tow package wasn't purchased, you'll need to add the fuses or relays to activate the tow package. I'd recommend you check your owner's manual or with Lexus, as I was unable to access an online...
