After my new Tesla frame-mounted receiver/hitch was installed, the 7 tab RV plug did not interface with my old Wells Cargo Cycle Wagon 4 pole (lighting only) electrical connector. Pollak and etrailer.com provided the perfect solution. A one piece, durable adapter that plugs and locks in place just as the RV type plug, and provides the perfect mate to the plug on my trailer. Voila! After testing the lights and satisfying all of my concerns, a little roadtrip for us proved this product to be everything I had hoped for and just what I needed!!

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

It adapted the 7 pole receptacle to the 4 pole that works on my boat trailer! Yeah. "5 stars for doing your job, part. Keep up the good ... thing that you were built to do!" I hope my work performance review is basically the same.

This item is a must have. Some trailers have 4 pins and others have 7. This adapter solves the problem. Well made item should last a long time.

This piece converts a seven pole RV connector to a four pole flat connector, the kind you'll see used by most rental companies like U-Haul. It sits firmly in place and never fails. Build quality is excellent. etrailer has a price that cannot be beat despite shipping.


Comments
This Pollak 7 Pole to 4 Way Connector Adapter is a very high quality piece of electrical equipment that adapts european plugs to US connectors. It works flawlessly. I very highly recommend it.

I used this product many times over the last year when pulling my trailer. No problems were noted during rain or shine or snow.

Although I am commenting on this product, I actually would like to comment on the following products. I purchased a brake system, tow bar, base plates and wire harness from etrailer. All of my orders were filled in a timely manner. When I reached out for technical assistance, the advisors were readily accessible. All of the products were installed by me. All of the products were very easy to install by using the video and instructions.

Worked perfectly with the factory harness on my 2017 Audi Q3.

it fits, should work fine, haven't used it yet never hooked my trailer up yet to my vehicle to check it, haven't gotten the trailer out of the shed yet this year as i didn't need it for anything, the plug fits my vehicle and the trailer will plug into it, other than that i haven't tested it to see if everything is ok or i have to do some rewiring, i have had that trailer hooked up to different vehicles and they were all different, my nissan was the worst but i always get it to work, i got the plug in case i needed to use my trailer

Product looks fine. Good value. Quick delivery, though to my neighbor down the street. A not uncommon situation with the carrier used.

One of my trailer connectors worked with some effort with this adapter. Unfortunately, one did not, so I bought a second unit locally for that trailer. THe connection cavaties are formed just a bit too close together.

Works as advertised. I converted my 4 way to a 7 way and the 7 pin connector didn't have an additional 4 pin availability. Oh well, this unit works great. Thanks Jesse at eTrailer!!

PK12716 Pollak 7 Pole to 4 Way Connector Adapter Well made, tough. Be gentle removing the trailer connection. The ground pin broke off of my first "Off Brand" adpt purchased frm Advance Auto.

I needed to relocate my motor home's rear license plate. In order to light up the rear license plate at the new location, I decided to utilize the existing trailer plug which needed to be converted to a flat 4 style plug. This adapter is what I needed to complete my project.


Comments
The adapter is exactly what I needed and still in operation after 1 year.

Worked great for the trip with my new trailer to the shop where I had new brakes and wiring installed. Now it is in the go-bag in case I ever need to haul a different trailer.


Comments
I needed this adapter when I rented a [rental] trailer for a one-way trip. Still a fabulous accessory!
