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, storage trays, and scuff panel to access this harness. Once you've plugged in the connector, open your fuse box and locate the fuse position indicated in the instructions. Then insert the included 15-amp fuse.
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.

The first harness was not made correctly contacted etrailer and was sent a replacement very easy to install
Right product in new condition. Best online price point and rapid shipping. Great job (again)! Thank you
Fits as advertised
Mazda CX9 2016. Works as advertised.
Everything was exactly as advertised. Packaging was tore up due to shipping in a cardboard box. Besides minor scratches on hitch everything was present and intact.
Etrailer continues to deliver. I needed to add trailer wiring to a vehicle. Went to etrailer, put in the vehicle and searched for the wiring harness. Two options came up with videos on how to install them. Watched the videos, ordered the wiring harness and got it delivered in 2 days. Installed the harness while watching the video and had it done in about 1 1/2 hours. I wouldn’t have had a clue about how to do the installation with out the video and the instructions that came with the harness weren’t helpful. Thanks!
Perfect fit Ty etrailer
Prompt shipping and delivered as promised. Communication from etrailer.com was fantastic.
Pretty straightforward on this one. Exactly as advertised. Instructional video on the website was spot on. Very easy. Lil disassembly, plug in, put back together. Got trailer lights!
Part got here on time, and fit easily, even easier than the video due (I think) to Mazda putting the ground wire in the connection. All I had to do was put the connector in, then test it. Worked great. My car is a 2018, and the video is for a 2016, but it is the same as far as taking the panels off.
Very easy to install!
Ordered a trailer hitch and wiring harness for my Mazda CX-9. Complete order received in just a few days, instructions were accurate and easy to follow, installed both the hitch and wiring harness by myself in 2.5 hours. Very satisfied. P.S. trailer installation video was very helpful.
The wiring harness was easy to install and works great. My only hiccup is that the install video does not exactly match the harness. Mine came with no need to run the ground wire. It is already wired directly into the loom. Also, instead of running the harness through the trunk and leaving it in trunk, I drilled out a plastic grommet next to the car’s harness and ran it out and down the inside of the rear quarter panel.
Plug for this device was well hidden behind the rear passenger interior trim. Finally found it but it was not as ‘accessible’ as I would have thought. Grommet under the spare tire is perfect for running the trailer plug through
Easy for install especially with the short video.
Plug and play! Super easy and clean way to get trailer lights added to car like factory setup.
Item came as described. Installation was made manageable with video instructions.
As always, etrailer delivers!! Bought from them many times in the past and they never fail to deliver a top notch product at the best prices and the staff is very knowledgeable . . . BUY with confidence!!
Took time but easy to install myself with trailer videos. Has worked excellent.
plug and play. easy to use and install
Plug and play great quality products
Super easy install. Watch the videos! Other places say to hang it out the trunk, but there's a grommet under the spare tire.
Easy plug and play
arrived without issue. installation was simple.
Super easy install, plenty of supplied wire length, excellent available install videos. Do it yourself and save a bundle.
No way this could be easier . Plug it in to the Mazda factory harness for the CX9 Signature and done.
