Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side tail light housing and behind the driver's-side rear bumper. You will have to remove the skid plate and floor coverings 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 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. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.The shipping box was badly damaged (due to poor packing) as was the hitch inside. I contacted Customer Service for a replacement and am still waiting to hear back. Very disappointing.
Outstanding quality wiring harness! AND YES the C57ER model does fit perfectly the 2024 VENZA LTE. Thanks again etrailer for a great experience. Now here are some hopefully helpful tidbits for anyone attempting to install this harness.
Follow the instructions since they are good. Except, in Step 3, you only need to loosen the drivers sidewall. Not necessary to repeat for the passenger panel. Once you do Step 1 that reveals the battery area which is all you need for connection of positive lead. A suggestion for Step 5, is to not do this until you have done Step 7 and have all connectors properly installed. It is easier then to position the black converter box and associated wiring. NOTE as for Step 8 this is not needed for installation on the vehicle since you already install the brown/red leads in Step 4! Skip Step 8 and move on! One last thing to remember is that you need to install the white wire with the ring terminal for connection to ground. The steps in the installation instructions does not advise you to do! It is stated on the bottom of page 6 with wiring diagram. I did not take any pictures but not sure if they would have added much to the installation instructions provided. A few hours of careful routing of wiring and you got yourself a nice hitch ready to go!
I received my order from etrailer this past Friday. Friday night I installed the hitch in an hour. Saturday it took me about 5 hours to install the wiring kit. This may seem like a long time but this is my first experience with a car install like this. etrailer’s directions and video were outstanding. The most difficult part of the job was detaching Toyota’s wiring plugs. If I were to do the job again, I bet I could do it in under an hour! A great experience for me, so glad I did it. Looking forward to trailing my daughter’s stuff back and forth to school!
I liked the product. I modified the install in that I put the trailer connector through the rubber grommet. I cut and butt connected the jumper harness and the 4-pole connector. I cut the 6 wires about 4-6 inches from the black box and poked the 6 wires through the underside of the grommet and butt connected each one, so much easier than trying to push the male and female plug through the grommet. I thought it was much neater to have the harness zip tied to the trailer hitch and not have to dig into the rear hatch to be able to plug it in. I have the Curt 53201 Auxiliary Automotive LED Light Strips for Hitch Cargo Carrier, Bike Rack. So I use it a lot.

Still working perfectly. One thing to note is that the brake and signal lights on the 2021 Toyota Venza are completely obscured with my Thule hitch in both the lowered position and the folded up position. I ordered 2 sets of lights, CURT 53201 Auxiliary Automotive LED Light Strips for Hitch Cargo Carrier, Bike Rack, 2-Pack CURT. 1 for each position of the bike rack, lowered or folded up. I joined them with, Trailer Wiring Harness Universal 4 Way Flat Y-Splitter Plug and Play Adapter Extension Harness for LED Tailgate Light Bar and Trailer Lights
Application: 2023 Toyota Venza. Took a couple of hours and everything hooked right up, no problem. Works perfectly on my home-built bike rack!
This is the third trailer hitch I've ordered this year, and the package is always come completely mangled once they've arrived
This kit is an excellent choice since it comes with just the right instructions to get the average person through the install. Even if you are not handy with wiring, this comes with everything you need which will eliminate errors along the way. Highly recommended.
Plastic enclosed item was intact. Has not been installed yet. We’ll see how well it works.
Easy install and simple solution for occasional trailer use.
A better power hookup would have made install easier. One plug in was not where supposed to be but was in better place.
Hitch was perfect. Trailer wiring kit was missing red, fuse holder battery connection. I alerted customer service.
Got this for my son to tow band equipment on tour behind his Toyota Venza. He says it was easy to install and works great! Excellent company to do business with.
This was not available in Canada yet for my Venza. Was exactly what I wanted was plug and play wiring. The video and instructions where easy to follow and took me 1 hr from start to finish.
While the 2021 Toyota Venza is not officially tow rated, the hitch kit here bolted right up perfectly and has met my expectations. Definitely worth purchasing if you have a Venza you plan to haul a light trailer with.
Fast shipping!
Very clean install. Everything you need is included. I would highly recommend this. No wire splicing at all. Splicing is all done for you and connector plugs are included for your factory wiring.
Haven’t installed so I cannot rate fair ly.
I put the trailer wiring in a 2021 Toyota Venza. The wiring harness and associated parts were good. The installation instructions were somewhat difficult to figure out. Installing the wire harness was difficult. All of the floor panels and pieces around the spare tire have to be taken out. The most difficult part was removing and reinstalling the driver side panel that goes from the rear hatch door to the rear door. To enable access for the part of the wiring harness that goes thu the floor to connect to the taillights below the bumper.
very easy to connect. Hitch was even easier and looks great as well.
Worked great
Got the hitch and wiring harness today, and it took me an hour to install both, with out any "HITCHES" very simple procedures especially if you watch the videos. Can't wait to pull my little trailer.
Thanks for a great product and instructions
The product was a bit more difficult to install than your video implied ( the plug behind the bumper was exceptionally difficult to unplug) and the included double sided tape was clearly past its expiration date. When I removed the protective covering it wouldn't stick to itself or anything else.

The installation of the harness is more involved then some when accessing the plug locations. I recommend going slow and completing all the installation steps carefully. You can use double sided sticky tape if the tape from the harness is not holding.
The instructions and video make it very easy
While not easy, easy , easy to install, the etrailer videos were very good. I'm very pleased with the finished product.
Great product easy to install
