Quickly and easily install a 4-way trailer connector on your Mazda CX-5 with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required. Converter is made using SMT to ensure superior performance.

Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side interior trim panels in your rear cargo area.
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. 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.

Great Product. Installed easily in my Mazda CX-5. It took very little time to install, and did not require any modifications to wires. You just plug it in, attach the ground wire, and it works, It is that simple. This is a great product and worth every penny.
Ordered harness 3 separate times. Had sent first one back it was incorrect for vehicle. Recieved 2nd one, took vehicle apart to find out 2nd harness incorrect as well. Had to pay shipping costs to return without getting correct part. Cost $[XX] for dealing with etrailer and no part. GGGGRRRRR!!!
I am quite happy with this wiring kit! It truly is plug and play!!
After watching the video, the install was quick and easy.
I only deviated from the install video, where it concerns the ground wire.
It says to use a drill and make a 3/32 hole and use the self tapping screw, if you can not find an existing place to mount the ground wire.
On the CX-5 there is a perfectly placed nut that can be used, and you dont even need any extra tools above what the kit calls for.
When you pull off the plugs for the drivers side tail lights, you will also see 3 10mm nuts that hold the tail light in place.
Just remove the one below the brake light, and slip the ground wire over it and replace the nut.
It was 97% plug & play. I had to drill a hole for the ground, and sand off the paint. Getting the trim push rivets loose was the most effort required.

I'll definitely take 97%! I also feel like you could recommend a few good whiskey's too if you don't mind sharing :)
Item was plug and play as advertised. Paper instructions included are marginal. Site provided video was very helpful.
This is my second installation using etrailer; they've been good to deal with each time.

Havent towed anything yet, but the cargo basket is very handy for transporting heavy, dirty matls
The trailer hitch receiver and wiring harness ordered was promptly delivered in good condition. All parts were brand new and just as described. I was very pleased with the simple ordering process and timely delivery. This company is definitely top-notch and I will be a repeat customer.
Well worth the money to not have to splice into any wires. Very easy to install on a honda civic.

Harness worked very well. Easy to insta ll.
The hitch was great and went on without a problem. Wiring also worked great. Done! I bought from you because of your videos and they made installation so much easier. I am a do it yourselfer but at 73 was thankful for all you information and help via the videos. Would recommend your site to anyone in need of a hitch.
I installed this on my 2015 Honda Accord for the purpose of pulling my small aluminum fishing boat and trailer. Works great!
Easy to install and still working well.

Love the ETrailer custom wiring kits, easy to install and functions well for many, many years. This is my second kit purchased and am always satisfied with ETrailer’s products.
Quick and easy to install. Quick ship. Works great.
Very nice quality. Great customer service from etrailer. Always a good experience!
Too easy to install!! I wish I could have found kits like this years ago! .. Kits like this should be the standard!
Ordered a trailer hitch for a Mazda CX-5. The etrailer team was knowledgeable, and I got exactly what I needed. The hitch fits perfectly and works great!
Great product and great service, easy plug and play install
Easy to install and works perfect.
Shipping was prompt and without issues. The install
On my 2014 Mazda cx5 was easy and stright forward. I watched the install video on the product page for CX5, and just
Followed the steps in video. Took 10min to remove interior panels, ect, and 10 min to make all plug and play connections, no issues.
Then 10min to put panels back in place. Tested the flat connector
As described in video. Works perfectly. This is after I went to Uhaul and they spent almost 2 hours under my CX5 baffled and unable to install a traditional trailer wire kit. I left with hitch only and installed this plug and play kit, completely satisfied.

Thanks so much.
My wife and I installed a 2" Curt trailer hitch (and wiring) on our 2015 Mazda CX-5. Total installation time was about 2 hours. We didn't have any problems with the instillation of the hitch or wiring. Etrailer has a video link available, which should be viewed before you begin your installation. However, there wasn't any audio with this.
The hitch is solid and appears to be well built. Occasionally, we pull a small aluminum trailer loaded with kayaks, or other light items.
We have ordered from Etrailer before and feel they are a good company to do business with.

Weve had our Curt hitch for over a year now and it still looks like new. Were very satisfied and recommend Curt and Etrailer.
