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.

Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side tail light. You will have to remove all trunk floor coverings and the rear scuff panel 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 trunk.
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 connector and installation were incredibly easy. The installation video was excellent, but didn’t mention the missing fuse. The reason for the One star reduction was the missing 15 amp fuse as mentioned in other reviews. Just added an extra trip to the parts store just for a mini 15 amp fuse. My hope is that. etrailer will add a fuse with each order, or at least suggest to sell an accompanying fuse so we don’t have to waste our time after we receive our product.
Received the harness without the 15 amp inline fuse installed. Neither the included directions or the video on etrailer make any mention of this fuse whatsoever, so I didn't notice it was missing until I hooked up my trailer and of course the lights didn't work. etrailer was of no help, they didn't know the correct type of fuse to get, and didn't offer to send me one, so that was 12 dollars out of my own pocket trying to figure out the right fuse.
Hitch fit perfectly. Great online instructions telling you what to take off or loosen. Have not installed the wire harness.
Good product. Installation video was so so. Battery access needs alot of explaination. Also never mentioned cutting the hitch cover panel.
The product works fine, but the instructions need work.
Drawings to show the details of where the clips are located would be much better than the provided photos. Black and white photos of a black interior just don't cut it!
Drawings of the clips would also be a good idea to give an idea of how they work. This would help a person understand how to release them.
Step 4 states "using a trim tool, remove the hatch threshold straight up" Where do you place the trim tool? A person could break or damage the hatch threshold if the tool is not placed correctly! It actually works better to use your hands than a trim tool.
Once everything was reinstalled, the powered hatch door would not close. You need to mention that once the battery is reconnected, the door need to be gently closed by hand. This resets the door closure mechanism so that the power buttons will once again work. This information can be found in the Mazda owners manual on Page 4-20.
Works great and the video you guys have for installation is spot on !!!
I feel that if I can install this, anyone can. Worked great when I needed to rent a U-Haul trailer.
The plug is super easy to install. The biggest negative from me is that the kit does not have the plugs that you would need to run the wire outside of the car. The kit recommends that you ball up the wire and place it in the spare compartment till its needed. Then you let it hang outside of the rear cargo door and shut the door. Its not a clean install
Josh was great to work with. Help me out with all my issues We'll buy.from e-tailer again.
Very easy instalation. Perfect fit!
Easy to install and great quality
Overall very good. Good components, great instructions (video and verbal) fast shipping. On the concerns side would be some damage to the shipping box (not the internals) and I couldn’t locate the fuses (not certain if I lost them, they weren’t included or they fell out through the holes in the shipping box). Overall , it feels like they went above normal to make it work
Box was damaged at my home.
