Adapter 4 Pole to 7 Pole Vehicle End Trailer Connector
This product works as expected. There is not too much to the installation, just plug it in properly and mount the ground wire. I did not find an easy way to mount this to my wife's Odyssey, or to the trailer hitch (item# 75270). Luckily, I do prototype design and manufacturing. So I came up with my own solution. I designed and made my own bracket to mount the 7 pole to the trailer hitch. It works like a charm, and looks great!
i had to replace these two items as my dear daughter went down our goat path driveway too fast. they replaced the originals from etrailer from the prior year. shipping is timely and customer service actually helps! i wired from battery to controller to hitch myself, and everything fit.

Adapter 4-Pole to 7-Pole and 4-Pole
After one year, the 7-pin adapter has been going strong without any problems.
Worked great.

Adapter 4 Pole to 7 Pole and 4 Pole w/Test Lamps
Not too difficult to install, but I would recommend using a car lift so you don't have to work from your back (review includes wiring harness and Brake Controller)
Perfect . My new Subaru hitch has a flat plate to which the dealership attaché the 4-flat. I used “2 L-brackets” to accommodate the 90 degree bend of the adapter bracket.

Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter
great site, helpful instructions and support. The install was easy because of those instructional videos. Great work! -Albert

Adapter 4-Pole to 5-Pole Trailer Wiring Adapter - Shorter
I put this on my 2016 Kia Sorento. Do yourself a favor and watch this instructional video "Hopkins Trailer Wiring Adapter Installation - 2014 GMC Acadia". Another great tip for my application is to buy an extra 20 feet of 16 guage wire. I ran the wire from the tailgate on the inside of the weather stripping and snaked the wire into the utility tray in under the back flip up compartment. When I need to hook up the adapter - I just run it out of the tailgate and hook it up. This keeps the adapter out of the elements when not in use.
Arrived quickly. I didn’t need to wire the extra lead to my reverse lights because my trailer doesn’t have surge brakes or backup lights. Simply plug and play.

Adapter 4 Pole to 6 Pole and 4 Pole Trailer Wiring Adapter
This adapter really cleaned up the installation and connected directly to the wiring harness. Maybe added an additional 20 mins to install this adapter but totally worth the time and money.
II use it on my towed vehicle behind the motor home. It allows me to take motor home power to a trickle charger in the towed vehicle and connect to the towed vehicle wiring. The four prong receptacle provides outlet to be used if there is ever in need for a four prong fitting good.

Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter w/ 4-Way Vehicle End Plug
Really easy to install. Plugs right in to the flat four wiring. I found a decent spot to mount the bracket and finished the installation. 5 minutes max. At this time I didn’t have to wire up a brake controller. That’s going to be a project for a different time. I would definitely recommend this product.
Worked out pretty good. Had a hard time figuring out just how to attach it. I ended up just zip tieing it. It was a life saver that I could pull the rear plug apart. Made it possible to slide part of the harness thought a tight hole.

Curt Universal Installation Kit for Trailer Brake Controller - 7-Way RV - 10 Gauge
I ordered this wiring kit for a 2003 Dodge Ram 1500 I recently acquired. The Ram was not tow ready but did have a factory 4-way. I also ordered hitch #13333. The wiring kit is very high quality and was easy to install. The 7-way fit perfectly where the factory 7-way would have gone. I'm using a Tekonsha Prodigy RF wireless brake controller so the blue lead was not needed but I left some extra should that change. Thanks etrailer!
Arrived on time and installing now

Mighty Cord Trailer Connector Adapter - 4-Way Flat to 7-Way RV Style - 12" Long
Product arrived via snail mail. Product did not work upon arrival. After examination determined the ground wire was not connected at the factory. Once wire was stripped and properly connected it did work. Poor quality control at the factory.
This is my second order with etrailer. Both experiences with your company have been very positive. The knowledge and friendliness -along with following up on orders and satisfaction have been much appreciated. Brittany, the customer representative, is a huge asset to etrailer.

Curt Trailer Connector Adapter - 4-Way to 7-Way RV and 4-Way Flat
I just installed this on my 2015 Volvo XC70. I also used the Curt XC70 plug and Play for wire kit. I watch two of etrailers excellent insulation videos. Installing the hitch and both the wiring products took me around 3.5 hours. I think Curt products are great and they are reasonably priced! e-Trailer makes your DIY installations easy. You just need to take your time when removing interior panels and double check your work. I used Volvo's torque specs for the bumper parts when I installed the hitch. E-trailer doesn't stop with just hitches and wiring solutions, they have just about anything you need to load and haul overhead or behind safely. What about performance? E-trailers got you covered. If you get in a jam during the insulation, don't fret or worry, call the text at e-trailer and they'll walk you through it. I want to thank E trailer and their professional staff for helping me with my truck and auto towing and lighting solution for over 10 years now!
This was/is a critical piece of any towing system, and as such requires extra care to hook up properly . I would recommend testing each connection as you hook it up being extra careful to make sure you are matching the terminals in the mating connector properly. This harness/connector performs perfectly when properly installed.

Perfect fit with easy installation instructions!

6-Pole Square Trailer Wiring Connector Kit (Car and Trailer Ends)
Bullet-proof connector, if not the most elegant. Used in my case for custom "adventurization" wiring on my 2007 BMW F800ST motorcycle, now just road tested this late summer - early fall 2017 on a three month, 18,000 mile loop out of Chicago through the Arctic & Pacific Northwest, including the Dempster & Dalton Highways. Had a custom wiring harness that had to be able to be removed in order to get at the engine, hence the need for the connectors. A few photos should be attached.
This is a product that I needed for my project, but was not easily found and available. etrailer.com not only had the product, but had it at a great price. Shipping was very fast and free for the amount I ordered. Overall, this was a great shopping experience. I made a bulk order of 16 as I am manufacturing trailers that are towed behind motorcycles. This product gives me the six conductors that I need in a very small package, which is great due to the size of motorcycles compared to cars or trucks. The only thing that could be improved with this product would be if they came with dust caps for each connector, or at least one for the vehicle side to prevent dust and moisture intrusion while the trailer is not in use. Keep up the excellent service and selection.

Hopkins Endurance Quick-Install Trailer Connector Adapter - 4-Way Flat to 7-Blade
It took awhile to receive my order, but I was informed by e-mail and was kept informed when I should expect delivery. Luckily, was in no rush, so I would reply and wait for an update from you. i received the connector in good condition. Thank you!
Installation went well and works fine. Only issue was the screws included with the product were not the right ones so had to replace which wasn't a big deal.

TorkLift Wiring Harness Extension for 36" SuperTruss or Cannon Hitch Extender - 7-Way RV
The wiring harness will not fit through the hole on the receiver extension. I had to unwire it and reassemble one end. I also expected there to be screws and nuts with the product. It now fits and looks good. Thanks
Excellent extension cord durable

48" Long 4-Pole Loop with Cover
The items I ordered will allow me to adapt my utility trailer for transporting my sea kayaks. Curt and Hopkins are both quality manufacturers. On a shipping note, the box arrived at the Post Office broken wide open. Your shipping folks need to wrap small, heavy, items in bubble wrap. Then stabilize it with foam peanuts. Just putting it in a box then stuffing the box with craft paper does not cut it. Items were not damaged so I am good to go.
I have now installed the following on my 2017 Wrangler: Brake light relay kit . Hopkins Towed vehicle Tail Light wiring kit. Blue Ox base plate. Blue Ox Patriot Portable RF Braking System. All of this has taken about 3 days of work spread out over a week or so. Overall it went well. Not too many surprises. Crawling around under a car at 71 is a bit of a strain but I'll get over it. I must say that Donna P. has been a wonderful source of great information and has stayed right on top of the process. eTrailer has been a great source for this project. I would recommend you all with no hesitation.

Nice adapter for my rv to motorcycle trailer. Easy to use and works great.

E-trailer: they've got what I need at a reasonable price. This is what e-commerce should be!
I received the product after just a few days. I had many technical questions that were answered by a competent service person. The product arrived in great shape and I had reviewed their installation video so installation went very quickly and easy. My 2011 Chevrolet Silverado is equipped with a 7 pole connection so I bought their adapter to convert to flat 4 pole connection. That an the CR-017 led worked very with first try. I also bought the trailer hitch lock at the same time. All products are very easy to use.

Adapter 7 Pole to 4 Pole with Tester and Cover
The product worked as it should. I really enjoy the built-in tester. I recommend this product. Shipping was fast.
ETrailer had exactly what I wanted at a fair price. Website was easy to navigate and purchasing was simple. Shipping was fast and I was kept notified right up to when I received my order.

Pollak Trailer Connector Adapter - Vehicle End - 7-Pole Round to 7-Way Blade
I received this item in a plastic bag, for a few moments i wondered if it was a knock-off. I had done my home work and was sure that this item would be compatible with the socket on my John Deere 2013 5085M at the time I ordered it, not so. The 'holding ridge' at the plug-in end was not in the right position when fully inserted into the plug on the tractor. I sent multiple pictures to Pollack Technical Support but they were unable to assist me. I finally modified the item myself (something I really hate to do) so that it would fit the plug-in and be 'grasped' by the cover/holder on the tractor side. As I anticipated, the thickness of the plastic was inadequate to make the adaptation 'sweet', so I had to cover the resulting hole with silicone caulk.
This is a great solution for adapting RV blade connector to 6 pole connector. I give it 5 stars. I use this for work purposes, and have found one issue that I DON'T believe to be manufacturer defect. In my industry we use different trucks and trailers daily, if not hourly. Some trailer electric brakes will lock up when adapter is connected. I have found the red wire in the adapter to be the problem. My solution was to splice in a switch so that when the intermittent problem arises I can flip the switch and be on my way.

Custer Trailer Connector Adapter w/ Dust Cover - 7-Pole Round Pin to 7-Way Blade
This product did not work. The diameter of the 7 pin receptacle plug was 1/8” narrower than my trailer plug. It fit perfectly into the 7 way blade receiver plug on my truck. I called customer service. She called manufacturer and manufacturer said there must be something wrong with my trailer plug. My trailer plug came standard on the trailer. Unfortunately no inside diameters are provided so one cannot measure before ordering. I am returning the product but was told I have to pay for shipping. etrailer has such a good reputation. I am really disappointed in this experience.
I have ordered several of these in the past from etrailer. Great product, quick shipping, an overall Great company to do business with.
