Say goodbye to the hassle of finding specific wiring kits for different cars! The Curt Universal Tail Light Wiring Kit stands out as a versatile solution, perfectly integrating with a wide range of vehicles, including those with LED lights. Whether you're prepping your 2022 Ford F150 or a Jeep Wrangler, this kit connects seamlessly, ensuring your RV's tail, brake, and turn signals communicate effectively with your towed car's lights. Its universal compatibility makes it a staple for every towing enthusiast's toolbox.
Protecting your vehicle's electronics is crucial, especially when towing. Thankfully, this kit comes with integrated block diodes that serve as a safeguard against electrical feedback that can potentially damage your vehicle's sensitive components. Drive with peace of mind knowing your vehicle’s electronics are secure, no matter the length of your journey.
Ease of installation can drastically simplify your towing prep, and this product delivers by featuring pre-installed butt connectors. By splicing quickly into your car's electrical system, it eliminates the need for complex tools or additional components. Whether you're a seasoned DIYer or new to the task, this feature makes installation straightforward and stress-free.
With the included 4-way flat connector, this kit ensures consistent and reliable relay of brake, tail, and turn signals from your RV to the towed vehicle. This ensures safety on the road, as all drivers behind you will be fully aware of your travel intentions. It's an essential feature for clear road communication.
To ensure your brake lights aren't overriding your turn signals during critical moments, consider integrating a brake light relay if your setup requires it. This additional step, particularly for cars where the brake light stays on after the engine is off, ensures both signals function without interference, keeping you safe from miscommunications that could lead to dangerous situations on the road.
When you purchase this kit, you're getting more than just wires. It comes with every necessary tool for installation, including a 4-wire harness, color-coded wiring guide, mounting bracket, extension cable, silicone sealant, zip-ties, and all required installation hardware. You’re fully equipped to get started and set up your towing solution without the need for additional purchases. Just open the box, follow the straightforward instructions, and you're all set for your next adventure.

I had some difficulty at my end when connecting to my 2004 Ford Ranger. My ability to use a multi-meter is not great, so I switched to a simple test light. Also, the wiring on my truck did not match Ford standard colors so I was a bit puzzled. Joshua at eTrailer was a great support, and once I figured out which wire was which on my truck, the installation of the new Universal Kit was easy. I was done within a few hours, including running the new wires all the way to the front bumper.
The installation went well, and it works as expected. The instructions rate it as a difficult install. At my age any work crawling around is difficult but the product went in without much fuss. Installed on my 2016 Kia Soul. Thanks for a good economical choice.
Pretty well just a box pf hardware. I bought some more diodes and figured out eventually
I didn't think the crimp connections were very good. I tried a number of crimp tools none that I have provided an adequate crimp. The wires would pull out too easy after crimping. Suggest the supplier might recommend the preferred crimp tool. I ended up removing the supplied connectors and using solder sleeves which worked well.
This required splicing into the tail light harness. I called and was told a plug and play was not available. I returned it after calling Curt who provided me the part number of a plug and play that I ordered on [online vendor].
If it had been plugged in play, it would’ve been a fantastic product. But because you have to cut splice and do the wiring, I give it a three.
unit did just what is was made for,,, works great
Not sure my installer used all of this item.

Sweet! Thanks George :) High-quality product for a high-quality kind of guy
worked great, good instructions
Great product
Worst nightmare ever! Our mechanic has a person who wires cars for trailers. He could not make it work ($XXX). We were rushed to get it working, before our big summer trip and a Car Electronics Specialist got it working for us ($XXX). I guess I should have gone with a Blue Ox wiring kit. But nothing but this one was recommended to me.

We do have several options for towing wiring for a 2007 Toyota Yaris. You can see them in the link below.

Easy and works well
I have bought off of you before everything was great this is the first time that I received something that was not what it was supposed to be or was used before the papers on the installation were all wrinkled and dirty and had writing on the ends of the wire were all cut and the connectors were not on I called your company and they made it right and gave me back my money except for my shipping and they told me just to keep it it's no good to me but thank you and I am still buying off of you
The kit was very easy to install thanks to the wire labels and Easy Fast Installation video available online. Now I no longer need the magnetic mickey mouse ear tow lights. Thanks etrailer.

It has worked so well that I have been telling other RVers that tow a vehicle to install the kit. Love youll at Etrailer.
Worked perfectly for wiring our car for towing. No problems. Would recommend for anyone!
Instructions were great and easy to ins tall.
Two mislabeled circuits. One on the left and one on the right. Difficult installation. Took two days to complete and my son who works on aircraft avionics was the person to do most of the install. It works when finally all installed correctly. Lots of metering to get this done. We did a more difficult routing through the car and firewall to hide and protect all the wiring. Also ran an additional wire if we ever add trailer hitch and need power for that install.
Easy to install. great how to video on the etrailer site. The video needa 1 slight improvement to make it more clear which socket (upper or lower) on the tailight housing to plug into.
etrailer was a great resource for me to establish my towable. Always available, replaced a damaged part with no issues. One of the best online large projects I've had. Went into this expecting the usual battle, but they were great.
Package improperly packed. Smaller box crushed by heavier base plate box. Paper dunnage only on top, not separating cartons inside.
Fortunately no apparent damage to product. Will test when installed.
This is a teachable moment for packing department.
Took less than 3 hours to install thanks to excellent instructions. No problems and has worked flawlessly for a year.
You customer service is fantastic !!
Well built, easy to connect & disconnect by myself.
I am glad I spent a little more for a high quality product!
