Installation
To determine where to splice into your vehicle's tail light wiring, you will need to consult the included instructions. Use the quick-splice connectors to attach the input wires of the tail light converter to the corresponding wires from your vehicle. To get the power necessary to operate, the harness must be connected to a 12V power source. This kit contains the power wire that connects the module to your battery, as well as the necessary ring terminals and butt connectors.
Once the harness is connected, locate a flat surface inside your vehicle near the tail lights and adhere the black converter box using the provided double-sided tape. Find a raw metal surface to use as a ground point and secure the white ground wire using the provided ring terminal and screw. Finally, secure the converter wires to your vehicle using the included cable ties.
It is recommended that you use a small amount of dielectric grease on the 4-pole connector to help prevent corrosion.
Because most trailers run on a 2-wire system - wherein the brake and turn signals are carried on 1 wire - the signals from your vehicle may have to be converted to be compatible with your trailer's wiring. If your vehicle operates on a 3-wire system, which means that it has separate brake and turn signals, then those signals will need to be combined so that they run on 1 wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.
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.
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.

Install a 4-way flat on your vehicle with this splice-in harness. Kit includes the necessary wiring to connect the module to your car battery for power. SMT construction ensures superior performance. Works with 2-wire and 3-wire systems.Really straight forward, I would suggest a longer cable and receiver mount kit as an option. I'd pay extra for one.
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 .

Continues to work great after a year of service.
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!
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.
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.
The part fit and performed well. The directions were not vehicle specific.
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.
Easy to install and works great.
I installed on my motorcycle trailer. Worked fine.
Everything I received was GREAT!
I have not had any problems with this product. It has been great!
