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.

Hopkins 7-Way RV Style Connector with Molded Cable - Trailer End - 8' Long - RV Standard
Çable good but after putting new 7way plug on truck cable wire colors did not match etrailers picture
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.

Pollak Black Plastic, 7-Pole, RV-Style Trailer Connector - Trailer End
Sooo, bought another one to match my truck side connection as GM uses Pollak, which are known to not play well with other brands. The design is just a wire clamp to wire it, which I did with the first one, but trying to get it secured I stripped out the screw. There are no torque specs provided. I’ll move to crimped ring terminals on this one and dial back the torque a bit.
Routine trailer maintenance. Absolutely nothing worse than fighting trailer lighting or electric brake issues when traveling.

Adapter 4-Pole to 7-Pole and 4-Pole
Really nice trailer wiring adapter. Very easy install. Takes about 30 minutes with all the tools needed. Drill, 7/64 bit for pilot holes to mount the bracket, flat blade screwdriver and 11/32 nut driver and two #10 self tapping metal screws with locking split washers and a couple zip ties to tidy up the wiring harness.
I looked at so many options before deciding on the B&W hitch, but I have no regrets buying it. There is nothing that my car is suitable for towing that this thing can’t accommodate. I even use it on the front hitch of my mower to move trailers around the yard! Adjusts very easily and stows nicely (though on my Ford Edge it rides lower than I like when stowed).

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.

Pollak 7 Pole to 4 Way Connector Adapter
I wanted one with a LED tester built into it to "trick" my SUV into thinking I had a trailer connected when really it was just a bike rack so the car didn't slam in it's brakes while reversing thinking it was something else. So I bought a different adapter. The picture slightly deceived me into thinking this had LED tester because the plug is attached by a rubber string (that I thought was a wire). So add another picture of the other side and that would eliminate my confusion. 4 stars because it probably works the way 99% of people would want to use it for.
Everything worked out well. On time and fits perfect. Attach hitch setup and my new Ridgeline. It comes with a 2" inch receiver and I have a full compliment of 1.25. stuff from my previous car. All from etrailer i must admit! so I needed the 2-1.25 reducer, a good lock, and the 7-4 reducer for my goodies! Thanks for the grest service

Hopkins Endurance Quick-Install 7-Way Trailer Connector with Universal Pigtail Harness - Vehicle End
Overall, I was very impressed by this connector. I used it as an in-bed connector for my gooseneck trailers. The plug seems to be a quality product, engineered to stand up to some abuse. I like how the mounting bolt heads recess into the connector and also how the bottom of the connector is elongated to help support the weight of the plug and wiring. I think it has a great shot at lasting for a very long time. The hinge is predominately plastic that will not corrode and break like the many I've had in the past.
Great Product quick and easy install.

Pollak Replacement 7-Pole, RV-Style Trailer Connector Socket - Vehicle End
It is a direct OEM replacement, easy installation. What I liked most was a real person answered my call and took my order, Katherine was very polite and knowledgeable. Thanks again. CJ
Worked out awesome. I bought this for a buddy for his used truck. The previous owners for what ever reason took it. Plugged it in and worked flawlessly.

Hopkins Heavy-Duty Trailer Coiled Wire Adapter 7-Way to 5-Way Flat with Nite-Glow
Still works great. The light up feature is great for knowing if a lighting problem is the vehicle or trailer.
The yellow wire coating is cracking and flaking off.

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!

Pollak Black Plastic, 7-Pole, RV Blade-Style Trailer Socket - Vehicle End
As the video indicates, ensure that your vehicle wiring is the same as the 7 blade definitions. Mine was not. Had to determine what color wire connections to use for a 4 flat adapter use on a dolly.
Service from erailer is always quick and efficient. The one time an incorrect product was shipped, the company beat a path to my door to get the right item into my hands. Every experience with them has been 100% positive. Great folks!

7-Way Molded Trailer Wire Connector - 3' Long
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.
After a year doing its job well.

Hopkins Endurance 7-Way Trailer Connector Socket - Vehicle End - Ergonomic Design
Well I wasn't able to use this as there was no good place to install on my car without it practically dragging. Not a product problem at all. I tried to return and customer service was fast and super helpful... unfortunately return shipping would eat up any refund. So.. I get to keep it. good quality and product. Very happy with it and wish I could use it. Will keep it for sometime in the future when of course I will need it.
I bought this socket for my 2006 Volvo Xc90 to wire in the 4-Pole harness I also purchased from etrailer. Already had a few 7 Blade to 4-Pole adapters from my previous vehicle, and wanted the option of adding a trailer brake wire for a small camper later on so that was the main reason for the purchase. It also went very well with the Hidden Hitch I had already installed, bracket mounted right up to the existing tabs on the hitch. Super quick and easy install, as all of my etrailer purchases have been. Looks great on the truck, and functions great with the 180 Degree cover.

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.
