Quickly and easily install a 4-way trailer connector on your Acura MDX with this custom harness. 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 interior trim panel 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 plug 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.

Very nice wiring kit and FAST delivery!
As expected.
T-connector installed easily and worked perfectly
seemed to hook up properly though I haven't use it yet
The installation was very simple and the quality was good. I haven't tested yet, but have bought two of these (for different vehicles) and everything worked as expected.
Great service and product, received a day after I ordered it from etrailer. The installation procedures were exact for my vehicle, took about 10 minutes to install. I would definitely order again from this company.
Worked great for my 2009 acura mdx
It's work like it should easy to install

Sweet! Happy to hear that :)
It could not get any easier to install this. LOVE it and it works fantastic.
Easy to install and easy to use.
Very easy install—no need to buy a more expensive harness. I ran it through the jack compartment to the panel on the left rear where it simply plugs in and I attached the ground to the lower existing bolt with the existing nut. Simple as that. The cover for the panel where it plugs in pulls off from the top with the help of a flat screwdriver. The instructions are very thorough.
Very happy with the quality and straight forward installation. Hitch and lighting work great.
I made a mistake on my previous review. I wasn't paying attention. The installation on this was a breeze. Decent instructions, although they were hardly needed.
Exactly what I was expecting for my Acura. Just a breeze to put in and worked perfectly. I can’t believe it ‘could have’ cost me $[XX] to plug in a wire?? THANKS!

Thats awesome, Steve! So glad to hear this harness worked out for you. There is nothing like a project thats completed smoothly!
The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, performed as promised. Thanks
Easy Install. Use the factory grommets in the floor and rear body to run the wiring to make it look like factory. Use the videos on their [online] page for guidance.
Easy to installed highly recommended for novice installer and dont forget to put the fuse in also
I have ordered several thing from eTrailer over the last few years and have been very satisfied. Everything I buy seems to ship immediately (usually same day) and arrives as ordered a few days later. Their installation instructions and videos are always spot on and have been very helpful. I haven't yet installed the wiring kit I just received but have no doubt it will work well and the instructions will be spot on.

Installation was simple. Only took a few minutes and with the video instructions you can go wrong.
Etrailer rocks like a young Mick Jagger.
I received my Acura MDX trailer hitch and wiring in less than 24 hours...despite the fact that it was supposed to be about 6 days ground.
online videos and great construction made installation a snap.
I will buy from Etrailer time and again

Weve put many miles on our Acura MDX trailer tow package from ETrailer and the whole rig right down to the wiring has performed flawlessly.
I've always gotten quality products from etrailer and the Curt line maintains that tradition. The receiver and wiring harness for my MDX are top quality, were really easy to install after watching the videos and saved me hundreds of dollars over the Acura branded parts.

After a year Im still very pleased with my receiver and wiring. I use the receiver at least weekly for a Thule bike rack, but the wiring harness only rarely.
Installation was straightforward as the videos indicated. Trailer hitch looks and works great. I am very happy with this purchase.
I installed the wiring harness, but to my disappointment it didn't work. When I was gathering up the parts and tools, I noticed that there was a red fuse in the plastic bag of accessories. I checked the controller and found there was a fuse holder on the power line. When I opened it up, lo and behold, no fuse. Installing the fuse fixed the problem and the lights then worked perfectly. If you look at the picture of the harness, you will not see the fuse holder, and the installation instructions never mention it. I'm sure the fuse was a product improvement, but the installation instructions should be updated to mention it.

I had the same problem. I had to watch the video on the website. The instructions included with the harness provide almost no help. Once I put in the fuse, the harness works fine. Also, the harness does not come with the pictured dust cover. Etrailer customer service is great and sent me a dust cover at no charge.
Product (trailer wiring) was delivered yesterday and installed after dinner the same evening. The install video on your website was a tremendous help, and I surly appreciate the knowhow of your installers. Took my time, was careful and it went smooth - anxious to test this coming weekend but I don't foresee any issues.

Still working great after a year of infrequent use but good to have.
Everything worked well. The wiring harness was easily installed as was the hitch receiver. Both have served me well the past year. Thanks etrailer.
