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 and passenger's-side interior trim panels in your rear cargo area. 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.Easy to install wiring harness connects to existing wiring and the kit gave you everything you need with exception to a couple electrical connectors that in the trailers video they also have available to purchase. All seemed fairly streamless install for the towing wire harness kit.
The etrailer components and install guide worked perfectly. Saved me hundreds from local retailers.
I already responded through an email, the hitch appears to be undamaged, it was lose in the box and punched 2 roughly 3" x 4" holes in the side of the box, the bolt kit is missing, my guess it went out through one of the holes! The Curt Wiring harness blister pack was pulverized by the 35 lb hitch and it's contents scattered all over the inside of the hitch package, I'm still checking to see if anything is missing or damaged, It looks like it went through a cement mixer! The tube of RTV sealant is now spread over the hitch and dried! The Curt Harness really should have been in a more substantial box, then placed in the hitch box for shipment! A blister pack will not survive floating around with a 35 lb hunk of iron! Other wise I'm satisfied It appears to be a very well built hitch!
I hate to mess with original wiring in vehicles. This made it easy and clean. Yes you could cut and splice or use splice connectors. But save yourself the hassle in a couple years when light on trailer or tow vehicle don’t work right.
I was very happy with my products.The harness was Great and easy to install. The adapter that holds the connector didn't have any fasteners to mount it.The hitch I had to open up the holes a little to get it to bolt up. Overall I was happy with the products and would do this again.
Straight forward installation. Works gr eat!
Easy install works as it should fast shipping id use etrailer again
Eliminated the need for splicing you just have to be careful and patient when taking the interior panels apart.
Hitch and light kit were an exact fit. Always a good experience with strainer!
I ordered my hitch and wiring harness on a Saturday and got them on a Tuesday. Installed the hitch on Tuesday night by myself and it fit like a glove.
Great service and great products!
I give high praise to the trailer hitch and wiring harness kit I purchased last year! The installation couldn't have been easier and the hitch fit like a glove on my Mazda CX9. The instructions were clear and easy to read. Thanks for a great selection of products!

Still very pleased with hitch and wiring kit a year later.
Installing the wiring kit was pretty straight forward. Especially if you watch an instillation video. If you have a lower sitting vehicle, you may have a tough time with the power wire. I was able to dive mine up ramps and get under it. I have one big problem with it, with everything hooked up my automatic hatch won’t close. As soon as I pull the fuse for the module, it works fine. I’ve contacted Curt and am awaiting a response. I’ll see how that goes and adjust my review accordingly. It is a 2009 Mazda CX-9.

After contacting Curt, they sent a new harness. It has worked perfectly ever since. I’m completely happy with the kit.
Product installs just like the instructions say. Routing the black wire to the battery area was the toughest part of the install. I used a wire to poke down from the battery area, taped the black wire to it underneath the vehicle and then pulled the black wire up to the battery.
Circuit tested and everything seems to be working. Next step is to check it out with a trailer.

No problems using it and I like that it stores inside the vehicle when not in use, which is most of the time.
I just finished installing the new harness, and have found that it also does not work. Looking into the matter more carefully, I've now discovered a fault in my power wire... so my old harness, just like the new one, was getting only a low voltage. I assume now they are both good!
I suppose now I have two good harnesses, the old one to keep as a spare.
The wiring did not take long at all. For me all the wires were long enough to make all connections. The videos show you have to have the pig tail come threw the hatch and over the bumper. I found on my 2012 cx-9 there was a plug on the back wall a few inches from the jack on the drivers side that was big enough from the plug to go threw.

What video? I need a video link if possible
Tremendous experience.
I ordered the tow light package for a 2010 CX-9.
It arrived 2 days earlier than estimated.
The video was very helpful and the install was not too hard.
One installation note: I elected to pull power from the "cigarette lighter" wiring found in the cargo compartment on the right side. I believe that the wire was yellow with a red stripe - it was NOT the black wire.
Thank you and good luck,

The item is just what is wanted and at the right price. Fast delivery. Only problem is with UPS is they deliver to businesses first and residents.
This is not the first time I have used "etrailer". Always got the right items and delivery was quick.
Great Job to everyone at etailer.

Great
The trailer hitch is a great fit. It did a little bit of fanaglyinhg to get it on properly but nothign to serious. I was able to do most of the work by myself but needed a second pair of hands to get it the intial bolts started.
Took about 4 hours to get it on as there was some level of difficulty to get it on as I was just working with jack stands hands, knees, and a rachet.
Unfortanately My car got recked a month later. I did get to use it 3 times before this and she did the job, no issues. Pulled about 1700 lbs the first 2 times over 100 miles and about 1900 lbs for about 50 miles.
For saving about $120 for someone putting it on for me, it was worth it. The price comparision buying it here vs other places etrailer has a good price and the product is good. I will note it did come in a semi weak box and had a few scrapes on it but noting extremely noticeable and nothing that would cause issues to the integraity of the hitch plus it's under the car, astectics shouldn't matter that much when it comes to saving some money vs buying it elsewhere.
I give it 4 stars becuase nothing is perfect and it was really worth the savings as it was solid hitch the did job with no issues.
Intake this in a 2013 Mazda5 while installing wiring to power the car taillights with RV lights for towing on a dolly.
If you follow the instructions and run the power wire down the driver's side of the car and install the converter on the driver's side, the install is flawless.
It has only been used to per the lights on the tow dolly, but it works perfectly. The converter, wiring and connectors are all of excellent quality.
Quick processing and shipping, perfect fit to our 08 Mazda 5.
Quality seems very good,directions are simple and straight forward .
Found a U Tube video with this product exactly, with hints on simple removal
of interior panels to simplify installation.

Easy hook up, very dependable.Thank you for a good product for my Daughters Mazda 3.
Everything worked as advertised! Just like everything else I have ever bought from etrailer.com
Yes, you may have to crawl under your vehicle to run the power connection. Took a little longer to install the hitch and wiring harness my wife was watching. :) Really, you can't go wrong with these guys and yes indeed, they stand behind what they offer!
This is the second wiring harness I have purchased for my vehicles from eTrailer.com and I have been very pleased. The installation video was most helpful. I watched it completely through before I even started in order to have a clear idea of what I was in for. Then, I referenced parts of it again as I went through the installation process. It took a little longer than I anticipated, but everything looks good and works great!
This wiring harness was super-easy to install. The most difficult part, by far, is running the wire up to the battery. If you have an automatic transmission (on a Mazda 5), you can run the wire completely on the interior (google it, there's a very good DIY). However, if you have a standard transmission like I do, the very convenient hole where you can put the wire through to the engine compartment is taken up by the clutch.
My only complaint with the harness is that the plug made a poor connection at first. After the initial install, the left turn signal/brake light didn't work on the trailer. After about an hour of troubleshooting, I gave the 4-flat plug a squeeze with a set of pliers and compressed the metal contact points by a hair. After that -- no problem.
Ordered a Class 3 Hitch for my 2010 AWD Mazda CX-9 - Super easy transaction all the way through installation. Ordering was easy, delivery was on-time, exactly what I ordered - While having has this hitch professionally installed, with Wire Harness, and 7 pin connector - Total ($80.00) I felt it well worth the price. Here is what I am towing - entrusted to an etrailer hitch
Thanks for a transaction that I can look back at and say "smooth" @ etrailer.com.....
Exactly as advertised! The installation video made all the difference, even though there were differences between the video vehicle and mine. I wouldn't hesitate to do it again.
