Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove all trunk floor coverings and the rear scuff panel 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 trunk.


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.


Powered Tail Light Converter with Surface-Mount Technology

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.


Curt SMT Circuit Boards

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.

I would give it a five star review, but I did have to troubleshoot the wiring harness. And result is amazing and everything functions as it should. I’ve seen other reviews of people saying that some of the pins are in the wrong spot. IN THE PHOTOS IS HOW THE PINS ARE SUPPOSE TO BE ORIENTATED ON THE HARNESS ON BOTH SIDES IF YOUR HAVING THIS ISSUE. Mine is a 2020 Toyota Camry XSE with the LED tails lights. If you’re having an issue where your tail lights aren’t functioning the way that the car is telling the trailer to. The issue is probably the orientation of the pins. Hope this helps. I do recommend buying this!!

I bought this for my 2018 Toyota Camry Hybrid. Install was easy following the directions but like many other reviews I have seen online the blinkers did not work. The brake and running lights did work. After a little investigation with a meter I noticed the wire for the right/left turn signals coming off the two pass thru connector sets did not line up with the wire connected to the blinker on the car. I cut and re-soldered the wire so on the right side/passenger side the tap off wire matched the car blinker wire and the trailer blinker started working See the green wires in the attached picture. I had to cut the green wire and move it over one position. I repeated the modification for the left/driver side and that one started working. So it works but you may have to cut and reconnect the green/yellow blinker wires. I soldered the wire when I flipped them over but one of those in line splices would probably be easier.

Turn signals and brake lights didn't work after install. After searching reviews I found that the majority of these for a 2019 camry did not work and were wired wrong from the factory. I bought a different brand off [online vendor] and it worked perfectly. Do not waste money on this for a camry. The [online vendor] unit was $[XX] as opposed to $[XX] for something that doesn't even work.

A good place to start is to double check all connections and make sure things are plugged all the way in. Another thing that is a common causer of issues is the ground wire not being properly connected to a clean, direct, and secure point.

I got the wrong trailer harness, but Amy was able to guide me in the right direction to get the job done. Evidently my Camry was made in Canada and it takes a different one. They gave me part number and although they were out of stock , I was able to get it ordered elsewhere, true customer service

  • Parts Needed To Tow Lightweight Trailer With 2019 Toyota Camry
    To tow the lightweight kayak trailer with your 2019 Toyota Camry you will need a hitch, wiring, ball mount with ball, and a pin with clip. For the hitch, I recommend Class I Curt Trailer hitch receiver part # C11576 which is a 1-1/4" hitch receiver and fits the hybrid model. I have attached a video for your reference. You will also need wiring to illuminate the trailer lights. I recommend the Curt T-connector 4-pole flat part # C34FR which will plug in behind the tail lights. When we...

  • Trailer Wiring Harness for 2021 Toyota Camry LE Hybrid with Incandescent Taillights
    I spoke with my contact at Curt, and from what I understand they're working directly with you on this. They're wondering if your Camry might have been manufactured in Canada, the Curt 56417 which we sell as part # C34FR won't work correctly on Canadian manufactured vehicles. According to Tekonsha, the # 118763 is a fit for all models of the 2021 Camry. The Hopkins wiring harnesses you specified are for vehicles being flat towed behind a motorhome, not for towing a trailer so they wouldn't...
