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.

20 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 30" Ground
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.
Your sales staff is second to none. Keep up the good work. You shipped minutes after I placed my order! Very impressed! Marty

35 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 42" Ground
on time as stated
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.

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)
Very easy install. My truck had a precut hole in the bumper for the plug. I then hooked the spare 4 pole plug into a Reese Universal mounting bracket and mounted it onto the hitch.

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.

48" Car and Trailer End Loop 4-Pole
As always,they had what I needed, good price, fast shipping.....and a video about how to use it. My go to place.
This wiring extension will do very nicely. I have a trailer with removable tongue.

4-Way Flat Trailer Connector w/ 72" Harness
Wiring and new self adjusting electric brakes were a simple install and work perfectly. The etrailer online video and written instructions made the job easy.
I needed a plug so I could pull my boat behind my camper. It was just the right length.

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).

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.

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.

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.

Hopkins 4-Pole Loop - 12" Long
Perfect product for my needs. My 4 pin is hiding under a cover on my bumper, so I used this device to plug into the vehicles 4 pin and allow the extension to hang below the bumper. Now I can quickly plug in to the adapter without taking a panel off. Cheap easy fix for a great deal of convenience!
I had purchased a Pro Series Cargo Carrier 63153 and the 20174 light kit. Assembly was very straight forward but I found that the 4-pole connector harness was too short. This 12" extension was perfect. Also, Jonathon at etrailer provided excellent customer support getting it to me while on a trip.

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.

Bargman 7-Way, RV-Style Connector w/ 6' Long Coiled Cable - Trailer End
I had to replace the old 7 wire cable because the male plug had been pulled off. I chose the WH54006-043 coiled cable. I used a 1/2 inch clamp to hold the cable up at the box and a Connect-to-Protect to hold up the male plug. The result Is clean and tidy. Thank you,
This should work great, installation is still on my to do list.

Pollak 7-Pole, RV-Style Trailer Connector Socket w/ Wiring Harness and Mounting Bracket
This is the product I expected and it arrived in factory new condition. To no fault of etrailer.com the currier wagon train and the ox’en that pulled the load were heading East. This was not the direction they were accustomed to so it took a few extra days. All in all good job I will do more business with this company.
I wish than all trailer wiring was color coded the same. I have wired a lot of trucks ant trailers and trouble shot problems and always solved the problems. this one gave some serious thinking since the wiring was color coded different. But it is working and I do like the Pollak plug.

Hopkins Endurance Flex Trailer Connector Adapter w/ LED Circuit Tester - 6-Pole to 4-Pole
Choosing the correct connector for my pop-up camper and F 150 baffled me before I asked etrailer for help. I got that help, bought the etrailer connector, and it worked like a charm. The lube that came with the connector was an unexpected bonus. Many thanks.
I was very glad to find this adapter so I can hook my bumper pull trailer to the wiring that is already in place for the gooseneck. Easy to order, delivered fast. Problem solved. Thanks

7-Way Molded Trailer Wire Connector, 6' Long
Only gave 4 stars because it was a bit confusing. I have a lot of auto wiring experience; from car stereos,amplifiers and all manner of accessories. All of the info on etrailer indicated that the color coding didn't match up. So I went into it disregarding the standard color coding, when in fact it was just as it should be.
Good thick rubber and plug works perfectly.
