Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area. You will have to remove the trunk floor coverings and the rear and side scuff panels to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.
Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.
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. 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.
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. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.Works as it says, very easy to install once you access the wiring as the harness just plugs in! Thanks for providing such an easy product that works!
I had a mechanic install the harness; he was pleased as it was just thread and click into the vehicle’s electrical system ( Mazda MX-5).
Great service, great products and great prices. etrailer knocks it out of the park every time!
Installed the Curt ca wiring kit and it worked perfectly, though lots of trouble running the wire through the car to the battery. Proud of the finished set up. And it is a sanitary way to handle the trailer wiring.
Got it quickly. and should be easy to install from their videos'
I installed a trailer hitch on my new 2016 Miata. The electrical harness worked great and was easy to install. You have to run a power line from the battery under the hood to the trunk. It was a little tedious, avoiding anything that moves or that gets hot. But I just followed the brake lines. Very satisfied. I would recommend it.
A bit challenging to get to wires but the harness was simple to install.

No problems.
I wanted a trailer hitch for my new Miata. The etrailer website was simple to use in making my selection, and it was delivered within a week of ordering. I recommend using etrailer to anyone in the market for a hitch.
This wiring harness is as advertised. The instructions were complete and easy to follow. Routing the power wire up to the battery and finding a way through the firewall was the most difficult part of the process, but with a little planning and persistence it all worked out just fine. I am very satisfied with the whole process.
Works great, pain to run the battery power cable but other than that a breeze.
Jameson and Donna P. were very helpful with my order. An item was out of stock and Donna quickly noticed this and ordered it directly from the manufacturer and updated my delivery date and my shipping address. Everything arrived on time and that was appreciated. Jameson answered my initial concerns and explained in detail what I would need to complete the job. Thanks to both and etrailer. I never realized there was so much to learn about towing a trailer, but they made it easy to learn.
I have not installed the kit yet, but is of quality stuff. Looks to be all there. it arrived in vert short time.
Product worked as advertised. Installation was very easy!
