  • 4 Flat
  • Powered Converter

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring - no cutting, splicing or tapping required. Powered ModuLite reduces strain on wiring system.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Tow harness with 4-way connector plugs into port behind rear bumper
    • ModuLite connects in rear cargo area
  • Includes ModuLite power module that connects directly to battery to avoid overloading vehicle's electrical system
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 2.1 amps per circuit
    • Tail lights: 5.6 amps per circuit
  • 1-Year limited warranty


Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness. The connection point for the ModuLite power module is located behind the interior trim panel in your rear cargo area. The 4-way tow harness plugs in just behind the rear bumper. Once you've made the required connections, insert the included fuse into the in-line fuse holder.


Once installation is complete, the 4-way flat connector will be stowed in an out-of-the-way location within your 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 Power Module

A ModuLite power module is built into this T-One connector. 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.

A challenge with the RX350 since you need to know if your car came from the factory with or without a towing package...this will determine the correct wiring harness. etrailer did a great job talking me though the specifics for my car to select the appropriate part. Very satisfied with etrailer...would definitely buy from them again...great customer service. 751626

2015 Lexus RX 350

2015 RX350 without trailer towing package. Worked perfectly. The plug to use on the vehicle was hidden from view. I had to reach back in the compartment on the passenger side toward the tail light. It was not plugged into anything. (White plug to white plug.) That was the hardest part which wasn't hard at all. After connecting the gray plug (gray plug to gray plug) under the vehicle toward the rear opening in the undercarriage moulding on the drivers side, I tested the lights and the all worked. Highly recommend this product. 688478

I am a lousy do-it-yourselfer and these types of projects are the kind of thing I usually do not pursue. However, when I came across the #118255 Custom Trailer harness by Tekonsha and that it would work with my 2015 Lexus Rx350, I was taken in by the ease/simplicity of the installation. When I reviewed the simple instructions contained in the packaging, I proceeded with caution, again, thinking that this is too good to be true. Well, I couldn't believe how it all came together. Still skeptical, I withheld from completing the outside wiring until I put the trailer light tester to the test. Wow, everything checked out fantastic!!! I would recommend this to anyone looking to install this type of harness. 544141

As other reviewers have stated, installation of this kit (on a 2011 RX 350) is a breeze, could be done by a below average 12-year old in roughly the same time it would take to check your tire pressures.. Looks to be high quality, and, yes, it works as it should. So grateful that [vehicle dealer] incorporated the connectors in the wiring harness, and further grateful that I could obtain a reasonably priced aftermarket kit to complete the set-up. 693174

2016 RX 350. This kit is excellent. Installs easily on the 2016 RX. Remove the trunk cover to expose the spare tire area. Remove the first aid kit (velcro) from the passenger side rear wall. On inside corner cover, pry up the center of black plastic fastener and remove. Reach under the cover with small plier and squeeze hidden second fastener's prongs to pop the cover loose. The white connector for the kit's 10 pin adapter, located in the passenger side rear location will have a black rubber sheath. It is located slightly up and out of sight toward the rear of the vehicle. Secure the adapter to prevent rattling. I used the tab with hole on the adapter with a cable tie to an existing sheet metal hole and some duct tape to restrain the wires. The four-way cable connects to an existing grey connector under the driver side rear underside near the bumper. Loosen the locking tab with a small screwdriver and remove the connector cover. Connect the cable and use cable ties to strain relieve the harness at your desired location. 448246

It took an hour to install this item, not complaining since I tend to move slower than most shade tree mechanics. It was fairly simple to do and it works just as advertised. Would recommend this product to others for sure. Just remove the aft plastic, pull up the side covering and you will see the connector right there. I went ahead and secured the device using a sheet metal screw in a bracket that I drilled under the floor by the side container. See pics. Did not need the trailer hitch wiring as this came with the Curt hitch. I now have a spare if needed. 593207

2013 Lexus RX 450h

I have a 2013 RX 450h without the tow package option. I purchased the Curt Receiver Hitch C13143 and installed it with no problems. I thought that my vehicle had the factory Tow Option so I ordered the Vehicle wiring Harness with 4-Pole Flat Trailer Connector- 118255 (for use with a vehicle that has the factory Tow Option). While waiting it's arrival I called the dealer and asked if my VIN had the factory Tow Option. It turned out that it did not, I expected #118255 that I had ordered was the wrong Item. It turned out that the wiring differences between the Tow Option vehicle and the non Tow option vehicle are the components in this kit (118255). The 4-pole cable plugs into a connector under the left rear bumper. (Remove the pan under the bumper). The converter module plugs into the connector in the right rear of the trunk. Just remove the small tray and it is near the tail light. Presto, power to the 4-pole trailer connector, it couldn't be easier. I read about etrailer.com in the Lexus Owner Blog and join the many others that sing the praise the company. 275173

AWESOME!!! I was a bit concern while making this purchase, initially. I looked all over and compared notes from Tow Ready to various other vendors and had a mixed bag of feed back on the compatibility of this on my 2013 RX450H w/o tow package. Tow Ready also did not list 2013 as a compatible year. Well, after only 15 minutes to install this, I can confirm that this is working just fine on my vehicle, I've also verified it using a multimeter on the output. A quick shout out to Julie H. at etrailer for her outstanding client service. Overall was an AWESOME experience!!! and would highly recommend this product and etrailer. 177171


Comments
Thanks for your comment, specifically regarding the the 2013 RX450H without towing package. I was able to install this part quickly and easily. Earlier I had installed the Lexus trailer hitch, which came with the gray cable and connected those pieces, but I only recently discovered there was no power to the wire harness. Now with the ModuLite Power Module installed there is power to the wire harness and my trailer lights work perfectly. I too had a great experience with customer service and support team Carrieann and Dustin

Fit our 2015 Lexus 450h perfectly. Instructions were very good, so was the video. Took about 2 hours, but I am far from a professional mechanic. Also didn't have the luxury of a lift. But, given how you can only see a few inches of the mouth of the hitch, hardly worth buying the Lexus factory hitch for more than triple the price. This hitch looks great on its own anyways. This hitch is beefy and well powdercoated. Nice hardware to attach it with. Holes lined up beautifully. I have no negative feedback. Only advice is take a couple pics before removing the plastic, wear eye protection theres a lot of crap and road dirt coming down on you, take note of which screws go where on the plastic to save time on mistakes on reassembly. 892106

Installed this in one minute. While I was I waiting for this to arrive I checked out the videos for our model SUV. Thanks for the videos. Note if you have a 2017 Lexus RX 350, to check to see if you have the tow package you check your VIN number at Lexus.com. Also note that to check to see if you have the tow fuse already installed, the fuse box to check is in the engine compartment by the battery. Pop the top off and check the diagram. It will be marked “TOWING” and is a 30amp. We don’t have the tow package, but the fuse was actually already installed. 845770

It was difficult to determine if a trailer hitch and wiring harness could easily be attached to our Lexus RX350 or if a special wiring kit was needed. The friendly customer service person helped pick out the right parts at the right price. The dealership told me it would cost over $1,000 for them to install the same items. We packed and drove from southern California to North Carolina. I am glad we had quality equipment going over those mountain ranges. I would recommend these folks for all your towing needs. :) 825331

This product absolutely worked in my 2017 Lexus RX 350. The shop had installed the tow package including the lighting harness. Unfortunately the lights were not working. They did not know about the "powered converter" that needs to be installed on the passenger side rear well (see pics). Once I connected the converter, everything worked as designed. I recommend a 4-pin tester to test before you need to attach a trailer. 800446

I just received today and installed. It was super easy and tested, all good, very pleased. I just use a utility trailer locally to bring riding tractor, snow blower as well as pick up yard supplies, etc. from time to time. I didn't have the TOW PKG. on my vehicle and this solved the no lights issue on the trailer. Thank you! 792657

This was installed on a 2020 Lexus RX350 F Sport. Worked well. This wire harness is in ADDITION to the wire harness included in Stealth hitch 391LXRX16T. Only the F Sport (or possibly a regular RX350 if without the tow package) needs this additional harness. 792448

    Yes, you do have the correct part. The Tekonsha # 118255 is the correct harness for your 2010 Lexus RX350, but I think you might be looking in the wrong spot. The plug you're looking for is located under the vehicle on the drivers side and not hidden behind the cargo panels as some other harnesses for the 2010 Lexus RX350. There is not an installation video available for this harness currently, but you should be able to find the harness easily near the bumper and under the vehicle....
