Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the rear bumper, along the driver's-side frame rail.
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. 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 - no cutting, splicing or tapping required. Converter is made using SMT to ensure superior performance.I recently moved to the Big Island of Hawaii where obtaining parts for vehicles has been very difficult. I have shy-ed away from utilizing the car dealers because their mark up on products are outrageous and turned to online shopping. I purchased a trailer and needed to replace the wiring harness on my truck in order to get my trailer street legal. I found the harness I needed on etrailer.com. The cost was very reasonable and they didn't charge me an arm and leg for shipping. Honestly I could have purchased two harness for the price the car dealership quoted me at. Normally when I purchase items online I receive it in 7 to 10 days. So when I got my box in THREE DAYS I was elated! I had no issues replacing the bad harness. All the electrical to the trailer WORKED! I wasted no time getting my trailer's safety inspection and registered so I can use it. Thank you ETRAILER!
Excellent quality. Loved the install video - really made it easy to get it up and running.
Works perfect!!! Fast shipping. Thank y ou.
It’s done the trick well fit in the plugs good
Install was a breeze, worked flawlessly during the first tow. Appears to be a high quality product with good fit and finish. What more can I say... It is exactly what I needed and expected. I used a bit of extra wire loom I had laying around to add extra protection to the wires going to the plug, but beyond that everything was right there in the package thats needed to get up and running.
(The Good)
The wiring harness is easy to install.
(The Bad)
The converter does not work properly on the trailer lights.
Brake & four way flasher lights work properly.
However parking lights don't come on. Also when the left or right turn signal is put on both of the trailer lights flash.
Truck is a 2005 Chevy Colorado Crew Cab Z71 without the 7-way connector

For the parking lights, the first step would be to find if the problem is in the vehicle wiring or in the trailer wiring itself. Use a circuit tester on the pin of the trailer connector fed by the brown wire while the vehicles headlights are on. If the pin shows power, the wiring harness and converter is fine. If it does not show power, and the connections are fully seated in place, then the wiring harness is faulty and should be replaced. The issue with both turn signals firing at the same time is a classic manifestation of a ground problem. Make sure the trailers main ground connection on the trailer tongue is securely fastened and not loose or corroded. Make sure each trailer lamp is securely grounded to the trailer frame, and that each connection is not corroded. Ive linked you to a help article about troubleshooting trailer wiring, I hope youll find it helpful.

Item was shipped in a timely fashion and it was exactly what I needed.
Plug and play on my 2010 Canyon. Dropped the spare tire, opened tail light connector, plugged it in. Made a stud to ground to (clean, good grounds are very important). I found a perfect recess to “tuck” the module into. Add a wire tie, wal-la, trailer light harness.
The wiring was correct for the truck plugins but the 4-way flat connector doesn't fit in the housing on the tailgate so it just blows in the breeze. When calling customer service through Curt they want you to buy a bracket they make. This is the third harness I've used on this truck and all of the others fit perfectly in the tailgate housing. Wouldn't buy again for a perfect OEM fit.
this is my 3rd one in 15 years they really work well when there working there are a lot of reviews in trailer wireing about trailer rite side brake lite not working they say check ground if its a ground problem you would have trouble with other circuits please check the t-connector for power on both sides first the box shorts out not supplying power to all wires
This was extremely easy to install in under 10 minutes works great & it all plugs together no cutting wires just drill 1 small hole for ground lug I put die electric grease in all connections & it was very affordable at only $xx.xx I got it shipped regular & was here in 5 or 6 days thanks e trailer for making a awesome product
This product worked as advertised and delivery was flawless and fast. These people know their business. Website is top notch!
Installation was so simple even a teacher could do it. Uhaul tried twice to hook up a trailer harness, neither time worked. Thanks to everyone at etrailer.com!
The hitch came quickly and complete. I bought this hitch because it is an American made product. I was surprised how simple the installation was for one person to do. Thanks for making such a nice product.
Got my trailer connector quickly and, as in past orders, done right done fast. I am completely satisfied. You guys should run the country!
went on easy and without a hitch (get it?) In all honest I ordered this and a hitch receiver and had it shipped to my house. I put the whole thing on the truck within about 40 minutes or so. Works well and was a simple installation.,
The amount of time it took to get this item was completely unacceptable.
The wiring harness works great. Thanks!
Works as it should. Great people to deal with
Very satisfied with the wiring harness. Everything went together good and works great. Get back with me in a few months and I’ll let you know if it’s still holding up because I will be using it frequently.
The trailer light kit shipped quickly, installed in a few minutes, and works great. There was even an installation video to help me with the installation.
I really didn't expect this harness to be so easy to install since nothing is ever this easy. It worked just like it should and would recommend it to anyone looking for a simple solution for trailer wiring.
Great product and very easy to install. Very simple instructions that are easy to follow. There's no cutting or splicing involved it just plugs into vehicles existing harness.
Fantastic item. Plug it in and go. Fit and works perfect
High quality wiring harness
Exact match and easy installation.
