Installation
This custom-fit T-connector plugs into your vehicle's wiring harness. The connection point for the 4-way tow harness is located behind the interior trim panel in your rear cargo area. Once you've plugged in the converter, insert the included 10-amp fuse into the integrated fuse holder.
Once installation is complete, the 4-way 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.
A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.
Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.
Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.
Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.
Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. Connectors plug directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.The website gave me the perfect fit for our Highlander. Shipping was fast and arrived on time. Installation was a breeze with the hitch and wiring harness. Great overall experience. FYI…I installed this entire system by myself in under an hour.
With the help of the online instructional video and the fact that Toyota had
already included the required wiring and connectors, the wiring kit for trailer lighting was very easy to install. Thanks
The harness works well and installation went great. Thanks etrailer for such great installation resources and videos!
This is my second order with etrailer. Both experiences with your company have been very positive. The knowledge and friendliness -along with following up on orders and satisfaction have been much appreciated. Brittany, the customer representative, is a huge asset to etrailer.
It fit perfectly and all the parts were in order. As always, I suggest Youtube backup installation videos to make the process super easy!
does not fit for my vehicle application. had to go to u-haul to get the correct harness...
Quality trailer wiring harness at a fair price with good pictorial install instructions.
Have not installed the hitch yet. Will be used for a bike rack and for a cargo carrier to transport a surf fishing cart to the beach. Hitch is well made but rather heavy. The order came earlier than expected which I appreciated.
Everything plugged in and worked well. The only reason it's not a 5 star review is because they didn't include the nut needed to secure the ground to the vehicle, and I unfortunately didn't have a nut that would work on-hand, so I had to waste an hour driving to the nearest hardware store to get an $0.18 nut that should have been included in the package.
If you're not sure what I'm referring to, in the video you'll see the ground wire typically connects to an existing bolt that sticks out under your dash. If you live far from a hardware store, you might first see if you have a nut on-hand that'll fit on that ground bolt, or put that on your list to buy the next time you're in town.
Very easy installation and it works great. I would suggest using etrailer's installation video rather than the printed instructions.
It was very easy and quick to install with the help of the step by step online video at the etrailer.com website
Good service, delivery and communication.
Connector head was wider than the drain hole. Had to shave off edges.
Works well and would purchase again.
I have a 2019 Highlander and the installation went very well. I bought the Drawtite hitch with the mounting bracket for my wiring plug, so I wanted my wires to go under the vehicle and not through the rear door. Once I removed the trays from the back of the vehicle, there was a rubber plug in the corner that could be removed that allowed access under the vehicle. I decided to use my box knife to cut a slit in the rubber plug. I had to cut my wiring harness across the 4 wires to run them through the rubber plug. I crimped them back together as seen in the photo. I used zip ties under the vehicle and inside the back to clean things up.

Nice job on the install! I would make one recommendation.. Id use some silicone to seal the hole in the grommet where the wire passes through to prevent moisture or exhaust gasses from entering the passenger cabin.
The connector was easy to install after watching the video, and worked well after installation. The whole install and check out only took 30 minutes
Great products. Install guides were well written and I couldn’t be more pleased with my whole “etrailer” experience. Thank you very much.
It was a very easy installation, everything needed was in the box.
Shipping was prompt. Arrival was without damage. Instructions were clear and easy to follow. Installation time was about an hour as the instructions predicted. The fit was perfect! The qualtiy seems good and the hitch looks good on my vehicle!

Excellent..no problems!
Fast service, arrived prompts. Product is as advertised ( I have to mount it), but Do not see any problems. Should fit as video suggested
Everything went well during hitch install. However, the wiring harness instructions did not clearly identify exactly where the extra fuse goes. Nor does the included 10 amp fuse match the rating in the fusebox, which states 30 amp. So ... will need to wait and see if it works. Great looking trailer hitch!
I just received the trailer hitch and the wiring harness about 2 hours ago. So I really can't read it yet. But reviewing the YouTube how to install them I believe I am going to be very very happy
I appreciate the assistance given me by the personnel at etrailer. They have always been very courteous and helpful. Would not hesitate to buy from them again. Thanks!
This wiring harness fit my 2008 Toyota Highlander Sport perfectly! It's very easy to install, especially if you watch the installation tutorial video. It's literally plug and play. Everything you need comes with it, including the fuse and zip ties to hold everything in place. The only hard part for me was getting under the dash and tucking everything away neatly, but that's because I'm a big guy and there's not much room down there. I ran mine to the outside of the vehicle to the hitch and installed it in a mounting bracket instead of leaving the harness inside the car and pulling it out every time I need to use it. There was an extra hole that had a rubber plug in it near the tail light area where the connector for the harness is. I took the rubber plug out and ran the wiring to the hitch. I filled the hole with silicone caulking on the inside and outside to prevent any water from getting in. I also wrapped all of my connections with electrical tape. The four way has a dust cap to protect the pins from dirt and debris when not in use. I installed it on the hitch using the mounting bracket (item 18144) here: https://www.etrailer.com/p-18144.html . Looks great! I tested my connections and everything works perfectly! Great product, great price, and you save a ton of money on installation by doing it yourself! Thanks, etrailer.com, for the great tutorial and product research!
very easy to install and wire. Directions very good. Fits well.
I was extremely happy with the etrailer hitch, l had a little problem installing the hitch because l had one bolt hole that did not line up, l did not have a vise to hold the the hitch in place move it a few inches however l did have a come along l was able to loosen two of the bolt attach the hook from the come along and ratchet the hitch bolt hole a few inches until it aligned with the hole on the truck body. I was able to screw in the bolt. The hitch looks great.l highly recommend etrailer for any towing needs
Hitch arrived w/in a week of placing the order, free delivery! Box was slightly banged up, but hitch was not damaged at all. Please note there is no interior packaging around the hitch. This was a self-install, one man job. Hint: watch the etrailer videos & other videos online as this will help a lot. I had no issues w/fitting the hitch but one of the tips I did use, was to reuse the box the hitch shipped in as support for the hitch during installation. I also used a scissor jack for final mounting to line up all bolts. I tightened to the recommended torque and was VERY pleased w/the final outcome. Passenger side under panel trim did not need trimming, drivers side did require a cutout but you can trim this smaller than the instructions detailed. Hitch looks great on my 2010 Toyota Highlander! Ordering from etrailer was easy & I would do so again, if needed.
