Gone are the days of cumbersome wiring installations. The Curt T-Connector Vehicle Wiring Harness plugs directly into your existing vehicle wiring without any need for cutting or splicing. It’s a custom fit designed specifically for your vehicle, ensuring that adding a trailer connector is as simple as plug-and-play. No special tools or electrical expertise required, making it hassle-free for any DIY enthusiast.
Protect your trailer wiring from the elements with the included dust cap. This small feature prevents corrosion on the 4-way connector, helping to maintain consistent performance of your trailer signal lights, even after your vehicle has been parked for long periods. It’s a simple yet effective way to extend the life of your connector.
For those worried about maintaining power across all your trailer's lights, the built-in jumper harness has got you covered. It includes relays that activate all necessary functions without drawing excess power from your vehicle, ensuring your trailer's stop, turn, and tail lights perform reliably. The system is designed to manage up to 7.5 amps per circuit for both stop/turn and tail lights, making it ideal for standard towing needs.
Tackle your installation with confidence using the instructional videos and guides that accompany this package. Detailed videos provide a visual step-by-step guide that demystifies the installation process. Whether you're tackling it in your driveway or at the shop, these resources make the process straightforward and stress-free.
Flexibility is key when owning multiple trailers. This harness is compatible with 5-pole, 6-pole, and 7-pole trailer adapters (sold separately), allowing you to tow a variety of trailer types without investing in additional wiring systems. It’s versatility that puts the power back in your hands.
Avoid a dangling connector that could easily get damaged in transit. With an optional mounting bracket (sold separately), you can secure the 4-way flat connector to your vehicle in a stable position. This keeps the wiring neat, tidy, and safe from potential harm, giving you peace of mind during every journey.
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind your rear bumper. Once you've plugged in the tow harness, connect the included jumper harness with relays to activate functions. You will have to remove the cargo storage tray, trim panel, rear subwoofer, and rear scuff panel to access the connection point for the jumper harness.
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.

I am 82 years old and either the help of my Swert we installed these without the help of a floor jack ! This is the third hitch o have installed from e trailer !!
The hitched are first class. The only reconnendation I would provide id two sets of bolts, 1 set metric and 1 set SAE. On some vehicles it is hard to determine which to use until you start the install. Saves a trip and cost to get the right size.
Product delivered as promised. The video for installation was very helpful too.
Didn’t think I could install the wiring myself using the typical kits that require splicing and tying into the battery. Then I found this kit that uses the existing factory wiring and it was the easiest install. The video provided were of tremendous help. Glad I didn’t pay someone $500 to install a hitch and wiring for me.
I bought this wiring kit to go along with the hitch that I also purchased from e-trailer. Both of them came with an instructional video that was excellent to say the least. They were spot on for my vehicle and the step-by-step instructions were so easy to follow I had the hitch installed and the wiring working perfectly in less than 90 minutes and I am not a professional installer. Their customer service he's also the best. They kept me informed from the moment the order was placed until after it was delivered to my house and even followed up to ensure that I had everything I need. I highly recommend e-trailer and will use them again for other accessories for my vehicles.
I'm not a "mechanically" handy person so following the instructional video was perfect. It's as easy as shown! A self tapping screw would be a nice addition to the kit. After the hitch is hung the use of the zip ties to secure the wires to the top of the hidden hitch was a nice added feature.
The end result looks great, functions as promised and installed as easily as shown!
I used this on my 2017 infinity qx60. It was completely plug and play. Factory wireing harness was hanging from the passengers side rear of SUV as stated. Plugged it in and it worked perfectly .
Etrailer.com is an excellent source. Great prices and great customer service. Thank you!
Arrived a day ahead of schedule and the installation instructions really helped simplify the install.
Hitch fit perfectly and instructions were great.
Follow the great video that is available thru etrailer website and you will not have any install issues..purchase the wiring kit and bracket and the install will go as planned. The products are built to last and fit is perfect..
READ AND FOLLOW THE INSTRUCTIONS before install...
Great company with good products
Works great for trailering my small sailboat and for my bike rack with my 2014 QX60. Ordered in the afternoon and it arrived the next day even on ground shipping. Took my local mechanic a couple hours to install the hitch and the Curt T-Connector Wiring.
Product and video worked great!
Easy as Sunday morning
Came really quick and price was right
Well worth it! Made the wiring a snap! The only way to go to wire in your trailer hitch. Great videos and reference pictures. Made it so easy.
Took an extra day or so for shipping, tracking info was off & i was sweating that it was lost...but showed up yesterday packed well. Quality and fitment were excellent- what I would expect from Curt- maybe they make these for etrailer I dont know for sure but seems like it... but I actually prefer the matte finish over the gloss. The Trailer wiring kit for Nissan was a bit more involved that typical, but fit well & worked out great- though the instructions werent. Overall It came together & I was able to get it installed for my customer so they can tow to their vacation, so Im happy & will turn to etrailer in the future.
Wiring was easy to install
Better than expected. Didn't realize my car was pre-wired for tow hitch, but it was and this kit worked perfectly. All plug and play.
I do wish they would have included a self tapping screw for the ground wire though. I couldn't find a bolt to remove from the frame that would fit the already installed round end and I had to drill a small hole in the frame to mount this. Had to obtain a stainless steel self tapping screw from hardware store.
Still great product though and has been working flawlessly for over a year now.
Installation videos were very helpful. Quality product.
Very professional and knowledgeable. Joshua was very helpful and answered all questions promptly. Parts arrived earliest than expected and were correct. Pleasurable experience overall
I installed this hitch myself, it took about 1 1/2 hours. The electrical harness and relays were easily installed with little electrical or mechanical knowledge. The video made it simple. I have used my hitch many times and I have had no issues with the mounting or the electrical. I’m glad I purchased it!
2016 QX60 Infinity.
Product gets five stars for plug and play function. The instructions were a little less than functional. After digging into the trunk to find the vehicle plugs as illustrated in the directions. No plug could be found. After unplugging taillights, rear panels, etc. Turns out my model year plugs were mounted tight against the aft wall, close to my knee (When standing at the trunk area.); high up and inside - but completely out of view. Still in the drivers side, rear corner. If I could have gotten my camera inside the bracing at an up angle, I would share a picture. All is well now and it works great.
I loved everything about this wiring kit! It was very well thought/planned out. With no need to splice anything, it was a snap to simply connect this wiring harness directly into the existing factory wiring connectors of my 2019 Pathfinder so everything worked flawlessly the first time.
