Most Popular Single-Function Adapter for 2020 Mini Cooper

Works, exact fit, high quality, coils tight so max of about 3.5’ perfect! Heavy duty wiring, great waterproof connections.

Item was just as I anticipated. It looks good, works great, and the delivery was as promised. E Trailer is a good place to do business.

Simple. Functional. Perfect for our needs.

It works, it doesn’t have indicator lights so it doesn’t make my Rivian think I’m towing unless I actually am. The cap is difficult to remove as it’s recessed into the unit, overall it does the job.

My truck has a dual trailer connection - 4 pole flat and 7 pin RV. When using my utility trailer, the spring loaded door on the 4 pole side exerts pressure on the trailer plug and wire, causing it to bend severely. Thinking this would be bad for wiring longevity, I ordered this adapter, which goes into the 7 pin side, and the plastic, sturdy body of the plug takes the force of the spring loaded door without the door touching the wiring. Then, the 4 pole trailer plug simply plugs into the 7 way. No more stress on the trailer plug!!

High quality with nonoxiding metal parts. The extended length 4 pin connector makes hook ups a dream.

Great well made product.

Perfect just what id hope for . the circuit tester was an added bonus. indicated left turn signal not working

My trailer has a reverse lockout that requires the back-up light signal to disable its brakes when backing up. This adapter did the trick perfectly.

Simple and easy to use; just plug it in and connect it to the trailer harness. Works like a charm!

Works as stated, just plug in to7 pin connection on car, and plug 4 pin to trailer. Nice feature w/ led lights to check if connection is good

Would be a good product if it were compatible with my Rivian R1T. The truck detects the draw of the indicator lights and insists on staying in trailer mode. I had to buy one without lights. I may or may not have used the compatibility feature of your website but you should be sure that it is set to not recommend this product to Rivian owners

Great product, just what I ordered. I couldn’t find this adapter anywhere else until I came upon it at etrailer.com!! I have ordered other products from etrailer and have been completely satisfied with those products as well. Thanks.

If you are looking for a 4-round to 4-flat adapter that fits the "heavy duty" 4-round plug, which seems to be rare, this is the adapter you're looking for. The pins on the "heavy duty" four-round plug are wider than the standard 4-round.

Exactly what I needed for my trike motorcycle. They knew exactly what I need to order . Quick delivery and very easy to talk with them for my needs

Excellent replacement for older adapter.Also,replaced the old worn out 6 pin connecter on the rv with a Pollak connector.

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.

Works for me??. Just needed a longer one for my utility trailer since I switched vehicles. Always easy and fast to work with etrailer. Thanks again

Great product well made , hope it fits truck & trailer

We have a camp trailer with a 7 pin round socket on the pickup, and needed a 4 pin flat socket for our new utility trailer. I wasn't looking forward to breaking into the truck wiring to install a new socket. Luckily I found this adapter at etrailer. I really like the fact that it has test lights on it. Makes it convenient. As usual etrailer's follow-up and customer service are excellent.

If I had watched the video I would not have purchased this connector. It says 0-5 feet, but it's only 3 feet. Additionally the 6-pole round end is female, which will not connect to your trailer/TOAD six-pin female socket. I couldn't find an adapter so ended up having to buy a completely new system at the last minute.

The coiled trailer connector adapter I order was shipped the day after my order and I received this item quickly. Based on my smooth transaction with e-trailer, I would recommend this website to my friends. In fact this site was recommended to me by my son-in-law.

This is a very high quality item.

A great addition to trailer management. Allows linkage and conversion of plugs.
