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.

Hopkins Endurance Multi-Tow 7-, 5- and 4-Way Flat Trailer Connector - Vehicle End - Ergonomic Design
Installed the Hopkins muti-tow 7, 5, and 4 way flat connector this morning. I ripped the original connector that was attached to the bottom of the hitch receiver off when I was 4-wheeling into the Doll House campgrounds in the Maze District of Canyonlands a month ago. So, I cut a hole in the bumper and mounted the new Hopkins connector, cut off the old broken connector mounting bracket, and connected the factory wiring to the new Hopkins device. Hopkins product installed easily, looks great, is now out of the way, and has the flexibility of multiple trailer connectors when required. I am pleased with the product. Attached is a photo.
Exactly what we had been looking for. Now I can hook up multiple trailers with different connectors and all the electrics on each trailer works. I mounted mine directly to the receiver hitch frame. The biggest challenge for us was routing the backup wire from the taillight housing, through the body of the truck to the connector. the rest went together fairly easily. Seems to be pretty solid and looks much better than the loose pigtail connector it replaced.

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.

35 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 42" Ground
Parts are good fit great no problem You get what you ordered thanks
Replaced the wiring and lights on my 1992 boat trailer. I was able to get everything needed from etrailer. I think Optronics is of the highest quality and recommend both etrailer and Optronics product.

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

20 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 30" Ground
Just what I needed for my home-built bike carrier. My wife rides an e-tricycle and by the time I loaded the trike and a couple of bikes on this platform, you could not see the car's taillights or blinkers. This harness worked perfectly!
Wiring worked perfect for my project. I replaced the wiring on my 14 foot utility trailer. If I was to do it again I would buy the next length up. I would have liked to have a little extra wiring if I was to ever need it.

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.

Curt Trailer Connector Adapter with Backup Alarm - 4-Way to 7-Way RV and 4-Way Flat
I never used it. It does not fit my motorhome. Still sitting in my garage.
Perfect fit with easy installation instructions!

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.

48" Long 4-Pole Loop with Cover
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.
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.

Great product no issues at all. Product as described & fit properly.
Pretty straight forward. I used it to switch my European trailer's connection to be able to connect to my Wrangler's 4-pin trailer hookup. No issues. works great.

Hopkins Endurance Quick-Fix Replacement 4-Way Flat Trailer Connector w LED Test Lights - Trailer End
Nice product & good value imo--it's very beefy and appears to be heavy duty---I know these are supposed to be temporary---that said this one replaced a Reese connector connector exact same style w/LEDs that was almost 17 years old before it failed--hopefully this lasts even close to that amount of time--I don't use this trailer daily usually not even weekly---so maybe with commercial trailer use this connector isn't for you..... It's my considered opinion that many of the fails are the result of a lousy install or someone disconnecting by pulling on the harness INSTEAD of grabbing the connector either way this gets an A+ from me
This is perfect. I needed an easy way to change the connector on the trailer I'm working on. It was an old pop up camper with an 8 pin connector mounted on the frame. but I only needed a 4 after rewiring it. So, out with the old and in with the new! Plus it's really easy to connect all the wires. Picture is not of the new connector but of the whole project I'm working on. I've since mounted all the running lights, tail lights etc.

Wesbar 4-Pole Flat Connector w/ Jacketed Cable - Trailer End - 14' Long
I rewired my boat trailer using the wesbar 4-flat connector from junction box to the hitch. I do wish the wesbar connector was available in tinned wire. I used tinned 14 ga tinned wire for the rest of the wire and ran a ground wire to every light eliminating the trailer frame as a ground. Also added a switch at junction box for a manual trailer reverse flood lights. Filled the junction box with removable potting Gel to prevent water/corrosion. Works great. No issues. Never been stuck on the side of the road troubleshooting an electrical issue / bad ground. Would purchase this again, unless I could find a marine/tinned wire version, then I would purchase that one instead.
We installed this cord on a tilt bed trailer that we use to transport scissor lifts. We have multiple trucks that pull this trailer and the receptacle on these trucks are in different locations. This required using a 4 flat extension on many of them and as you would expect, the extensions come up missing and of course no one knows what happened to them. We tried every trailer supply store in the Phoenix area and no one carries a cord like this. Because this one is 14' long, we can cut off what we don't need and wire it into the J-box on the trailer and make it long enough that we don't need an extension. Great product.

The website was the first indicator this would be easy. Logically laid out, suggestions for complimentary hardware, good photos and demo video's to make selection easy. The ordering was easy, I received timely updates, who actually worked on my order and again, timely updates. Order arrived quickly and is exactly what I needed. No drama, just received my order promptly. What more could I ask for?
E-trailer: they've got what I need at a reasonable price. This is what e-commerce should be!
