Installation
This custom-fit T-One connector plugs into your vehicle's factory tow package wiring harness, which is located behind the rear bumper, on the driver's side.
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 plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into OEM tow package port - no cutting, splicing or tapping required.It is made clear that this harness is for a vehicle equipped with the factory tow package. What is not clear is that if you have the harness plug on your vehicle, that is not indicative of having a tow package. Granted there are other components that would be obvious that a tow package is present, but it seems logical that if the connection is present, it should work. In order for the trailer lights to work, you need a converter box. Some sites show it as a 4/7-way pug adapter, but the picture is wrong, keep checking other sites to see the actual device. Also, there are plenty of forums that discuss this problem. The converter powers up the harness and the connection will work. The converter, which is simple to install, is about $xx from [dealership]. The kit supplied by etrailer is way more involved than the factory converter. Just be aware that the presence of the factory plug itself is not indicative of having a tow package.
The wiring harness came with just the wires, no mounting bracket, no zip ties, and no instructions. I wish it had some sort of mounting bracket. We had to zip tie it to the hitch receiver to keep it from trailing on the ground, which looks pretty ugly. Otherwise, it works well.
Easy install and fits the bracket perfectly. The receiver bracket and wiring harness make for a professional looking install.
Perfect plug and play harness. Removed the factory plug cover, added a little dialectic grease and plugged in. Wire tied the excess harness to the body molding bracket, pushed the flat connector through the bracket, added some dialectic grease, and slid the coverover the plug. Simple process
Install took me about 2 hours used car ramps and floor jack did by myself on a creeper this Included installing the wire harness
Easy. Check for the hookup connector under the rear of the car. My 2022 Highlander Hybrid has it, and it wasn’t spec’d out with a trailer package. Don’t forget to put in the 30 amp fuse.
The service was very good.The hitch came in 2 days.It took my son in law 20 minutes to put it on.Very happy with this product.
Ordered this simple trailer connector December 12. Very small part and chose to have it sent economy (=USPS). The post office was overwhelmed and providing substandard service. Thanks again 2020. I contacted trailer on Dec 21 and spoke to Danielle. I explained how I needed the part for a post Christmas need and really had expected it to have arrived already. Danielle was very professional and listened carefully. Although it was still to early to initiate a call she said she’s would follow up the 23rd. AND she did, I received an email from Danielle with a status from the postal service and some kind words assuring me that it was on the way. It did arrive on Christmas Eve as described. The review is: disappointed with the post office and highly recommend the outstanding customer service from etrailer!! And the wiring adapter is good too.
I had great help from the staff, getting the wiring kit, and hitch for my rig. The tracking of the order was nice. Everything arrived in great condition. The unit was correct and fit great. I give this company a (A+).
The wire harness was a perfect fit for my 2020 Toyota Highlander gas model XLE
Perfect! Exactly as described. Best to reveiw the how to install from the internet to make it go smoothly!. Great product!
Would do business with these guys anytime. Super fast delivery and excellent customer service with delivery and product
I easily found the trailer plug under the rear bumper cover of my 2021 Highlander Limited. Initially I was not clear on whether I needed a converter. The answer is yes! But the converter plugs in at a different location. The converter plugs into a socket located behind the left rear interior quarter panel. There is a really good video of this on Utube. What you need is etrailer part TK99FR, which includes both the trailer wiring harness and the converter. Since I already had this wiring harness from etrailer, I used a Toyota converter (part 725-48200) that I obtained from a local dealer. Regardless of whether you use the etrailer converter or the OEM converter, it is a super easy connection to use the plug-in provided by Toyota. No splicing needed!
It works it fits. I just wish the shipping was cheaper to Canada.
Good but you need the inverter adapter for the factory harness if you don't have the tow package
Easy to install but doesn't work. Did some additional research and maybe should have bought the TK99FR which comes with some additional adapter or something. But nowhere did it say to research this possibility before ordering. You see the TK74FR stated clearly that it would fit my vehicle. Frustrating!
Great fit for a fraction of the cost. Easy to install and great documentation. I recommend following the forum for lots of tips on how to DIY this.
perfect. i recommend using etrailer.com
Good fit and continues to work great.
Excellent parts and service
Bought this and a trailer hitch. Both went on very smooth thanks to their videos and sending me the right parts. packaging contained all the parts and manuals too. Shipping was VERY fast; they had it on the courier the day I ordered it.
Installation was a breeze. Following the video and with the aid of a friend, the hitch slipped into place without any hassles. Used the Pig Tail I purchased with the hitch which is "plug and play". Completed the task with the purchase of the Toyota Highlander Tow Converter from a local Toyota Dealer. The Quality of the hitch speaks for itself! IMHO, the hitch looks superior to the "through the bumper" OEM assembly.
Perfet fit!
Works with my factory pre-wired Highlander.
Plug and go
Easy to plug into wiring for 2021 Highlander that had wiring tow package,
