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.
Tail Light Converter with Surface-Mount Technology
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 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.

worked the first time because I read the other reviews and watched the videos (don't forget the fuse!)- the one thing I wish was a video on how to fish the wire under the car so I don't have to run it out the back door each time.

So far the product does not work correctly and initial fix did not work. I am awaiting a call back from technical support to discuss the issue more in detail. I think there is something wrong with the harness. The installation is very easy and straightforward but my results are not good. Turn signal connections have power all the time and should not but they seem to work correctly when you simultaneously apply the brake. This would indicate the turn signals only work correctly when the brake is applied. I hope to hear back from etrailer sometime soon as I may miss my time window to get this working. A correct working harness would get 5 stars. Will update review if I get this issue fixed.
by: Andrew07/27/2019
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.

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.

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

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.
by: John B03/06/2015
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.

Everything worked well. The wiring harness was easily installed as was the hitch receiver. Both have served me well the past year. Thanks etrailer.

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.

Buying from retailer was a snap. I researched this purchase for a while. etrailer had the best prices and was loaded with information. Hitch and wiring arrived quickly and as described. Having watched the videos on their website installation was a breeze. I would not hesitate to order from here again.

Part and installation exactly as described. Took me 2 hours - start to finish.
Being in AZ I didn't have any rust etc. to contend with nor any threading issues. I did use WD40 on the rubber pieces and in the holes for the bolts.
My driveway is at a slight down slope - so I backed into the garage (chocking the front tires) and further elevated the rear-end with the use of a 2x6 and 2x4s. This allowed me to have several additional inches of space. Also - for the spare tire - use the spare tire crow-bar to lower the spare tire (pop the little plastic piece on the floor of the rear end, insert the crow bar, then rotate counter clockwise - the tire will then lower).
I did not have a 2nd set of hands so I used a bungee cord to hold up the hitch on the passenger side while I drilled the first bolt on the driver side.
It helped greatly to have a drill with a socket adapter (3/8" and 1/2") and extension for each. Picked up the adapters before installing after reading the reviews of tight quarters and painstakingly manually tightening the bolts. Adapters are $4/each at local hardware store and totally worth it vs using a manual socket.
A torque wrench is highly recommended since I used the power drill to screw in the bolt - then I used the torque wrench and surprisingly it required a bit more turning to get to the 136lbs of torque required as called out in the instructions.
I took a pick of all the tools that I used to install.

- Electrical Needed For Towing a Coleman Pop-up With 7-Way Behind a 2011 Acura MDXThe 4-Way # C56038 is going to need to be combined with the 7-Way Kit # ETBC7 you found to be able to tow your Coleman pop-up behind your 2011 Acura MDX. While we do not have a single kit for a 7-way the 4-way ties into the wiring for the brake lights, turn signals and running lights. Then the 7-way kit you found will provide the wiring for a charge line as well as a brake controller like the Redarc Liberty # RED52VR. I personally prefer this type of controller for your Acura as it only...

- What is Needed to Add Curt Brake Controller to 2010 Acura MDXYou're on the right track; to add the Curt brake controller to your 2010 Acura MDX you'll need to add the 4-way as well as 7-way that comes with the # ETBC7. You will first install the 4-flat, which will activate your trailer's lighting functions, and you'll then plug that into the 7-way that comes with the # ETBC7, which also gives you the wiring, circuit breakers, and rest of the hardware needed for installation. The exact parts you need are the following: - Curt T-Connector Vehicle...

We do not sell a version of this that also provides a 7-way, but if you are towing a trailer with surge brakes most likely you wouldn't need a 7-way.
