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 rear driver's-side and passenger's-side tail lights. 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 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.
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.

The wiring fit perfectly and the instructions were good
The harness is very good quality and the actual connections area snap but getting to the connectors behind the tail lights was not easy for me. There are no videos made yet for the 2020 and 2021 highlander installation and the instructions are not comprehensive on the body panel separation needed at the tail lights to get to the connectors. I was concerned that I was going break something. I did two additional things for my installation also. First I enclosed the wire from the battery in a 3/8 plastic wire loom slit tubing for added protection, and secondly, I did not use the crimp connectors that came with the kit but soldered and heat shrunk those connections instead. I also put a drop of solder on the pre made white ground wire connector. I made sure all the wiring was secured with zip ties as best as possible wherever I could get to it. It’s not difficult per say to install this kit but it was time consuming for me and a bit nerve racking behind the taillights. Final result: works great!
I wish I had bought a towing package with my new Highlander regardless of the cost. Then it would have been plug and play and no concern. I routed the wiring to the best of my ability to hug the bottom of the car but know that if I ever drive off the pavement (and I use my car for everything) there is the risk of something snagging the power wire. I also found regular butt connectors vs heat shrink sort of cheesy - did not use. Was also very nervous in removing tail lights and re-installing. Only takes one break of something to wish you had never gone this route.
This Curt T-Connector wiring harness was relatively easy to install on my 2020 Highlander. I tried the behind-the-taillight version and it was a no-go. After a year of use I haven't had any problems.
Products (Hitches ) are excellent, very easy to install,(even without directions. Videos sure were helpful too. Great,quick response from your employees. Sure beats the dealers in explanations and prices. WILL DEINITELY USE AGAIN.
Excellent customer service, great pricing and on time delivery.
Very easy install on my 2021 Toyota Highlander .
Highly recommend purchasing products from etrailer.com
Thanks again etrailer
I have done business with E-Trailer a lot in the past and as always I received Excellent customer service. The products is as advertised with the best price I could find.
Easy -up and it works the way it should.
It doesn't fit my vehicle, I ended up paying shipping to send it back and paying shipping to get the right part.
Everything I needed was in the kit and has been working great since installed.
It fit perfectly
Looks great on our vehicle
