Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area. You will have to remove the storage trays, rear scuff panel, and trunk liner to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.
Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your rear 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.

First it didn't work but problem I have with the negative wire conection.made a good conection and it start working good . Customer service amazing. Thanks.
The wrong instructions were enclosed with the wiring harness.
THIS RESULTED IN MY WASTING A LOT OF TIME.
I am working with Curt to get the right instructions.
Necessary!
Works as it should. Have used it for over a year now.
Installation was fairly easy with video instructions.

I have been towing more than I should and it hasnt fallen of yet. Thats very good!
Works great. I used it with my trailer and traveled 8000 miles and everything worked amazing
This is nice. I saw a hitch someone else had put on their Prius Prime and it looked cheap and thin. This Curt is beefy. The powder coating is thick. Well worth the money. Etrailer's system when you purchase includes the video to install. Very helpful when you order

No issues to report. It made it thru a New England winter and is ready to rool for another jetski season. Great product.
Well made, all parts fit the car. I think the one error in the instructions is that the butt connectors are not heat shrink.
Easy to install, works as advertised. 10/10 would buy again.
I did this installation on 2021 Prius Prime. All parts fit perfectly. The most difficulty was fishing the 12v power wire from the hitch to the battery because I used a floor jack and did not have much space under the car. One tail light plug for one of the jumpers was on the right side of the trunk instead of left. I called tech support and we tested the tail lights with the plug disconnected (the tail lights didn't work- confirmed we had the right plug) then installed the jumper (they worked correctly -so we knew we installed the correct jumper). The converter box and ground connection had to be installed on the right side of the trunk vice left as shown in the video. The videos were extremely helpful.
This is a quality kit and service from etrailer was outstanding as always. Using this on a Prius Prime it was most comforting to know this wiring kit isolates the trailer from the complicated and expensive electrical system of this vehicle. Draws power specifically from the small 12v cabin battery and independently fused as well. Used their video found on [line] and I installed this myself.
I used this for the 2018 Prius Prime and everything worked out just fine. To start, my kit was missing the black silicon that comes with it which was not a game changer but was unfortunate. I also wished they included the heat shrinking butt connector they featured in the video instead of the regular butt connector.
Now that my small complaints are out of the way, the install went smoothly, especially with the perfectly narrated video that walked me through the whole thing. If you don't have a lift, two jack lifts will do just fine, but just be prepared to be under there for a while. Overall, quality product with quality instructions. Thanks etrailer!
1. Something drew down battery when only driver side was connected but charged battery and proceeded.
2. Video very helpful but might mention that passenger side connectors are not near lights but behind hitch towards the middle of the car.
Once all was done, following the instructions worked fine.
Excellent produit, expédition très rapide. Merci

You pay more for this wiring kit, but the cost is insignificant compared
to the possible cost of repairing any car purchased in the last decade if you used a cheaper wiring kit. The wiring kit etrailer sells isolates the power provided to the trailer from the power provided to components in your car. If someone makes a mistake at the interface with the trailer
wiring, the car is isolated from any damage. The cost is right, too, as
etrailer offers it a true $30 discount.
I am 75 and installed the wiring kit myself. three times (2006, 2014, 2018)
in my Prius vehicles. etrailer videos and static photos reassure that you are doing the installation correctly with the least hassle.
I've used etrailer twice now. I tried saving a few bucks by buying a hitch/wiring combo on a popular auction site. They sent the wrong parts and I waited too long before trying to install them.
I own a Prius and the seller sent stuff for a Buick.
I will never buy trailer stuff from anywhere but etrailer.
These guys always get it right.
Trailer lights work great!
You guys worked with me and helped me in every possible way. I am so happy with your product and you have Awesome customer Service team. Thank so much
This is my third purchase. And couldn't be happier. the hitch and light package were perfect. the install took less than three hours by myself. Thanks again.
the instructions and pictures were very helpful. running the cables and making the connections much easier with your guide. I will tell all my friends to go to etrailer
Same I don’t even open.
