Some vehicles have separate turn and brake signals, while trailers use a combined signal on each side. The Curt Powered Tail Light Converter Kit with 4-Way Flat Trailer Connector takes care of that for you. It merges those separate signals into the combined setup your trailer needs, so your lights work correctly without extra adapters or guesswork.
If a short happens on the trailer, the converter box acts like a safety barrier. It isolates the issue and prevents damage to your vehicle’s wiring and electronics. That extra layer of protection makes this kit a solid choice for vehicles with more complicated taillight systems or multiplex signal inputs.
The included 4-way flat connector gives you everything you need for standard trailer lighting—running lights, turn signals, and brake lights. It’s the common setup for small and mid-size trailers, and it easily plugs into most trailer wiring.
This splice-in kit works across a wide range of vehicles and installs wherever needed behind the tail lights. Just identify each function with a circuit tester, connect the wires, and you’re good to go. It’s flexible enough to handle basic towing setups or serve as the first step when upgrading later to a 7-way system.

Ratings & Reviews
I looked up the part using the make, model and year of my vehicle and it was very easy to find. Also there were videos that were also helpful in seeing how the part was installed.
everything we needed to complete the job
Continues to work great after a year of service.
The part fit and performed well. The directions were not vehicle specific.
Great product and great support! It went in about as long as it took to wash the video. most excellent.
Easy to follow instructions
I have not had any problems with this product. It has been great!
Worst customer service ever .
Easy website to use, prompt shipping and a quality product!!!
Original order trailer hitch and light converter kit had wrong converter kit. Replacement for converter kit shipped to wrong address (garage I hired to install trailer hitch). I had notified etrailer that I wanted replacement converter kit set to my home. No offer from etrailer to rectify the situation by sending another kit to my home and sending a prepaid shipping envelope to the garage to return the mistakenly delivered converter kit.

I am sorry that this order has been difficult to locate. I see that our customer service department is currently working on getting a replacement for your order sent out to you immediately.
excellent on line guidance on best options, fast shipping, great customer service
I installed on my motorcycle trailer. Worked fine.
Really straight forward, I would suggest a longer cable and receiver mount kit as an option. I'd pay extra for one.
Easy to install and solid build quality. The wire taps this kit comes with also work very well! I used a wrench to easily squeeze the wire tap plate down, before shutting the blue clip.
For those of you that want a super knit picky review: the double sided tape isn’t strong so I used gorilla double sided tape instead. I wish it came with at least one more wire crimp (ended up using my own when I ran out of the two in the kit).
Highly recommend curt, I’ve installed this on my car, and a few of my families cars. It’s always worked like a charm with no issues. One of the cars has been using this curt wire for almost 10 years, no issues at all.
Works as expected. I cut the trailer connector off and spliced in additional wire so the I could route it through a grommet and do a permanent installation at the hitch receiver.
Product worked well. Installed on a 2013 Porsche Cayenne S for a bike rack that mounts in the hitch reciever and has brake/turn/tail lights on it. Only reason I didn't give five stars is I'm not a fan of scotch-lok connections and it would be nice if the wires to connect to the vehicle harness were a little longer. Didn't hinder installation or operation, strictly a preference thing. No hesitancy to use this kit again.
Good stuff
Installed on a 2016 BMW X5. I had the hitch professionally installed, but they didn't want to do the wiring. They thought something special from the dealer was required. After pricing a module from the dealer, I decided to roll the dice with this kit. Great choice. It was incredibly easy to install, and it works just fine. No issues at all!
Installed on a 2015 BMW X5. Super easy to hook up and lights all work great. Installed when I put on the hitch so we had lights hookup. Would highly recommend and super handy.
Love this system! Installation on my 2015 X5 was very simple, straightforward. I did have issues for a period where I kept blowing the 10 amp power line fuse. Customer support was good, and I eventually found that mice had chewed into my trailer wiring causing intermittent shorts. After fixing the wiring on my trailer, the Curt system has performed flawlessly!
Easy installation and the best value. The extra money for the "kit" is only needed for the butt connectors and the in-line fuse, but having it all together in a package was certainly convenient. If you already have butt connectors (16-18 gauge?) and you can source an in-line fuse line cheaply, you can save some money. The extra lead for the positive power line in the kit is unnecessary on the BMW X5 F15 depending on where you're locating the box. If I had needed it, my package was short one butt connector to have used it (the image of the converter box shows a pre-attached butt connector to a black lead...that wasn't there on mine and I used one from the separate packaged installation "kit"). The installation video for the BMW X5 F15 (2014-2018) was perfect.
Only a 3-star rating because of short leads on the product. If the power wire were just 6-12" longer it would be perfect (I still didn't need any extension), and the green lead for the right tail-light is too short. I was able to get it there...barely...and I'll need to come back and splice in an extra 12-18" of wire so there is no risk of it being pulled when servicing the batteries or compartments. The product only includes the bare minimum lengths, and even then it only worked because I was able to tap it into the larger wire bundle closer to the bottom of the compartment rather than at just few wires separately leading to the tail light.
Worked without issue. Clip on connectors are a bit fiddly, but that’s not the kits problem, otherwise everything worked as advertised.

Worked well with U-Haul trailer, no issues, everything worked as expected.
I bought this kit for my 2015 Honda Fit. All is fine with three exceptions:
1. The green wire that runs over to the right side turn signal was not long enough to reach the right side turn signal wiring!!!! CRAZY, no excuse for that.
2. The blue connectors included do not work. When you clamp them down they do not make contact with the Honda Fit wires. Apparently the Honda wires are too small. Curt should know this. I had to remove all blue connectors and carefully squeeze the little metal plates inside the connectors so that they make contact with the tiny Honda wires. It was a frustrating pain in the rear to diagnose the problem and fix it. Come on Curt, FIX this issue.
3. Lastly, some of the Honda Fit wires were not the colors that Curt said they were. You must test all Honda wires, regardless of colors before making connections, not the end of the world, but confusing none the less .

Product has performed flawlessly.
Have not installed yet. So far so good
Install took a while but overall a 2 out of five beard job. Buy a heat gun and nice crimper and shrink all connections.
