Features to know about
Installs Without Cutting or Splicing: Plug-In T-Connector
Wiring a trailer can be a hassle, but this Curt T-Connector makes it simple. It plugs right into the factory tail light connectors, so there’s no splicing or wire tapping required. Everything hooks up cleanly behind the panels, keeping your vehicle wiring intact and the install stress-free.
Clean Power Connection: Powered Converter with 12-Volt Lead
The powered converter keeps the trailer lights running smoothly without interfering with your vehicle’s electrical system. It uses a dedicated 12-volt hot lead that runs to the battery, giving the harness its own power source for reliable signal strength and protection against overload.
Ready for Standard Trailers: 4-Pole Flat Connector
The built-in 4-flat connector provides running light, turn, and brake signals—everything needed for most small trailers or accessories. It’s a standard setup that works with common trailer plugs, so you can hook up and go without extra adapters.
Compact Setup That Stays Hidden: Factory-Style Fit
With its hidden design and plug-and-lead layout, the harness tucks out of sight once installed. It connects neatly through existing trim and grommets for a clean look and lasting protection from moisture or road debris.

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.

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.

It’s been a year and no problems with wiring. It has dual hookup, so I can use a couple gadgets I got when I fashioned a grille mount on the hitch I got from Etrailer. Handy Dandy! Like I reviewed before, you can stop looking, this is the place you were looking for. Lots of quality parts at an awesome price. You got a question? Call them up they’ll answer your questions, and they’re nice folks. That’s as valuable as anything else.

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.

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.

- Wiring Harness for 2023 Mazda MX-5 MiataHi Phil; the only way a trailer wiring harness avoids running a line to the battery is if the vehicle has a factory tow port already. The Curt T-Connector Vehicle Wiring Harness # C56300 you ordered will plug into the connection points in the rear cargo area of your 2023 MX-5 but, you will still have to run the hot lead up to the vehicle battery. Is this for an accessory or are you towing some kind of small trailer?

For the 2016 Miata, if you do not already have a hitch, them I recommend the Curt Trailer Hitch Receiver, # C11435.The hitch will install to your vehicle without any drilling or welding required. For a wiring harness, the Curt T-Connector Vehicle Wiring Harness With 4-Pole Flat Trailer Connector, # C56300 is confirmed to fit the 2016 Mazda Miata. The connector will plug into...
view full answer... - Can 2020 Mazda CX-3 Carry Mobility Scooter Using 1-1/4" to 2" Adapter and Cargo CarrierHello again Chuck; if you want to carry that mobility scooter on your hitch you will need to find a cargo carrier that fits a 1-1/4" receiver without an adapter. We don't have any with a ramp but there may be some out there that will work. If you use the Trailer Hitch Receiver Adapter # e43YR, or anything else like it, you will reduce the capacity of your hitch by 50%. I'm sure you have a hitch like the Curt # C11418 with a tongue weight capacity of 200 lbs. Cut it in half and you can't...

If you measure approximately 2 inches downward from the lowest point of the bumper fascia, you'll have a pretty accurate idea of where the underside of the receiver would sit. If you'll be using the hitch for light-duty towing, you'll need a few other items to complete your...

- How Do I Run The 12 Volt Wire To The Battery When Installing Wiring On A 2021 Mazda MX-5 Miata?Running the 12 volt power power wire for the Curt # C56300 on your 2021 Mazda Miata can definitely be tricky. This really should be connected to the battery as this will keep the wiring from causing any interference with the vehicle's computers. With that said, I included an install video we have of this wiring harness being installed on a 2020 Miata that should help the process. What we did was follow the brake lines up to the engine bay and made routing them a lot easier. Following these...

For your application we need to look at an alternative to a roof rack on your 2017 Mazda CX-3 because the Thule Tepui Explorer Ayer 2 Rooftop Tent, like the part 901201 in blue, is not supposed to be installed on a roof rack that uses clamps to install on the vehicle. This is because the weight of the tent could damage your roof. Any rooftop tent that I've looked at the instructions for have this same instruction - they are only supposed to be installed on roof...

view full answer... - Trailer Hitch for 2016 Mazda MX-5 Miata for Towing Jet SkiYes, the Curt hitch part # C11435 is a confirmed fit for your 2016 Mazda MX-5 Miata and would have enough capacity for pulling a jetski trailer. It has a 2,000 lb capacity which would be more than enough. For trailer wiring you'd then need the part # C56300 which is a confirmed fit. This installs by plugging inline with the taillight connectors for an easy install. For a ball mount you'd then want the part # C45521 and ball part # A-80 and pin/clip part # F-4.

view full answer... - Dim Trailer Lights with Curt T-Connector Installed on 2017 Mazda CX-3 with Vehicle OffIf sounds like you may have LED lights on the trailer you are towing your 2017 Mazda CX-3 with. What is likely happening is that is a little bit of power on the lighting circuits for the T-Connector # C56300 and since LEDs use next to no power that little bit of power is getting through to the LEDs. I confirmed this with my contact at Curt. If this is the case then the only things you can really do is just unplug your trailer wiring when you will be leaving it parked for long periods of...

view full answer... - Which Trailer Wiring Harness for 2019 Mazda CX-3Although both the Curt # C56300 and the Tekonsha # 118718 are both fits for your vehicle, I'd personally choose the Tekonsha harness, as we've found that they tend to be a bit more reliable over time. If you haven't yet decided on a hitch, I'd recommend the US made Curt # C11418. For a ball mount, Curt recommends the # C45521. For a trailer ball, use # 19256 for a 1-7/8 inch ball or # 19258 for a 2 inch. I've linked to install instructions and an install video for the hitch.
