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!
this connector along with the short L bracket and the mount bracket- gave me a nice connector to my hitch. Though I used the short connector and did have to slightly bend it to allow the 4 to 7 pole connector to fit. If Id bought the long L bracket-- It could have worked-- but bending a little worked well.

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
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.
I recently had a receiver hitch installed on my 89 Silverado and the wiring was merely zip tied to the safety chain connection. Well that didn't sit well with me. I wanted a more permanent wiring connection point. So I purchased your 4 flat to 4 flat and 7 way plug and installed it. So far so good. The installation turned out perfect and it looks good. The test lights are a great thing as well. I couldn't be happier.

Hopkins 7-Way RV Style Connector with Molded Cable - Trailer End - 8' Long - RV Standard
7 pin connector separated from cable. I was expecting that "Molded Cable" meant that the connector was fused to the cable insulation but instead, the two separated almost immediately after I installed it. It still works fine as the wires are connected securely inside the connector but with the outer covering pulled out like this, I don't think it will last very long.
Worked excellent for wiring my cab over camper to in bed trailer plug-in.

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!
Easy doing install and works great thank you

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.
Exactly what I was looking for. Easily connected to my existing 4-way without any additional wiring. The 7-way adapter bracket was the correct size, and the holes were pre-drilled for the right fit to connect to the existing bracket on the (U-Haul Installed) tow bar.

Pollak Black Plastic, 7-Pole, RV-Style Trailer Connector - Trailer End
Product so far has worked great for a pinched/cut OEM 7pin cord. It isnt weatherproof like an OEM connector to the cord-as well as the female end of the connector but then its just the connector so totally sealed is not the design for this. It works fine & currently has saved me from having to purchase a connector & wire cord as 1 piece & some shennagins with installing that set up.
Dunno It took 36 hours from "shipped" email until it left the Wentzville P.O. this morning. Don't think it will get the other 400 miles by tomorrow morning.

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!
Easy install thanks

7-Way Molded Trailer Wire Connector, 4' Long
Worked great for my application. The wire colors for 7 way plugs aren't universal so I had to pull up a pinout of a 7 way plug and ohm out the wires to the plug to confirm what went where. But the quality of the plug is excellent. After a year of use on a salt water boat trailer it works great. Just makes sure you heat shrink your butt splices and a little dielectric grease in the plug goes a long way.
When I ordered this harness I thought I was getting a standard 7 way for a conventional trailer with brakes. What I actually got was a harness made for a camper/RV hook up. The wires have all the colors you would expect but all the lights/turn signals are coded into the plug completely different. After spending a good deal of time carefully matching, soldering and heat shrinking all connections to my new trailer harness, I was very dismayed to find only the brakes actually worked. After a bit of research I found a schematics page on the etrailer site and discovered the problem. As this is a molded plug I could not take it apart and just reposition the wires inside the plug. Another full hour or more of rewiring followed and now all is well. The harness itself is of very good quality but was not labeled/identified properly. This could have been prevented if etrailer would clearly label this harness as a camper/RV harness only.

Pollak Replacement 7-Pole, RV-Style Trailer Connector Socket - Vehicle End
I had to replace the socket in my truck after I forgot to disconnect the plug when setting up my camper 1 year ago. Since then, I've connected the camper 35 times and pulled it over 6,000 miles. I have had no issues at all with the new socket.
product from Pollak is always great but they packed it with steel couplers and destroyed it

7-Way Molded Trailer Wire Connector - 3' Long
Of the seven wires only two were in the correct position, the ground and the 12volt hot.none of the others matched with the harness on the tow vehicle, which I purchased from etrailer and it was fine.
I've had this in use for over a year and they don't build them like they use to. I use this on a gooseneck trailer and the piece of plastic behind the spade connector for the clearance lights and brakes has melted, allowing the spade connector to lose contact with the plug on the pickup. So the lights would cut off in the middle of the night and would have to wiggle the connection till I could fix it. I have an older Hopkins plug and never had this problem. To fix the problem I ended up putting pieces of thin copper wire behind the spade and have done it twice since the plastic melted a 2nd time and once again the trailer clearance lights would quit working. Attached are before and after pictures.

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.
I have ordered several adapters and complete trailer wiring harnesses from Etrailer. All have been top quality. I have saved a lot of money on the plug and play trailer harnesses. Several hundred dollars when they are factory installed, less than $75 from Etrailer.

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.
Got it just when it said it would be here. The 7 into 7 plug that was ordered is already on the truck an trailer. Thanks Guys.

7-Way Round RV Style Trailer Connector - Trailer Side
Perfect fit to change our trailer from a 5 pin to a 7 pin with added capabilities. we are long time etrailer customer and they always ship fast and have affordable prices to suit our needs.
On etrailer’s page it had etrailer name on connector, that’s what I thought I was buying. When it came it’s a Pollack. I could have bought one at my auto store. Very disappointed with the advertising of it being an etrailer item. I’ve ordered for years from them, not anymore.

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.
worked fine. was very well made. i used it to pull my Deere baler with the ton truck to the dealer for repair. it'll be on hand for many years for that use.
What our customers are saying:
"very easy to shop"
