Tossed a shovel in the bed of my pickup and busted the outer cover off of my electrical connection for my cabover camper. Replaced the cover for under $20 vs buying a whole new plug. Fit perfectly and highly recommend. Thanks for your help Nichole!

works as designed. installation straightforward

Ordering could not have been easier. Product was received in two days. Fit and finish of the product is excellent. Instructions were easy to read and installation was simple. Shipping was about 60% of what was originally quoted when ordering so that was a nice plus. This product looks like it will last a long time.

Totally trouble free.

by:
a great fit for my 2014 jeep grand Cherokee. Plugged in to the wiring provided by Jeep from the factory. Also, the 7 to 4 pin adapter fit right into the now 7 pin plug so I can tow U-Haul trailers, pop up campers, etc. Thanks so much!!!!
by:
I used this to replace a connector that I had broken. It plugged into the existing wiring perfectly the mounting holes did not match the old one exactly but as that was a different brand it was to be expected. The Hopkins appears to be heavier duty than the old one and should stand up better.

As with all previous orders with etrailer communication was great and shipping fast and items well packaged.
by:
I love this product. Snapped right in. My mounting bracket hole configuration was a little different. I drilled 4 new holes, 4 new screws. Done
My trailer plug fits nice and snug.
Thanks for a nice product.
by:
My factory connector cracked.
I installed a Hopkins plug on our trailer several months before, so I purchased the connector. It is a great product and easy to install.
by:
I always check with trailer first. The always have what I am looking for and always at the right price. Shipping is fair and I have never been unsatisfied with the products.
by:
This part was a direct replacement that I needed. The retail dealer that originally installed it coud not get it for me. etrailer was great, had exactly what I needed, was easy to order, and arrived in 4-5 days exactly as promised. The price was good, and shipping was reasonable.
by:
Exact fit. It has worked great for thousands of miles. Much better than the one it replaced.
by:
Bought this for my 2011 VW Toureg and it fit perfectly into the original small 7 pin factory attachment. The only complaint is that only one of the holes matches up to the factory cable holder on the VW. So I can only screw in one of the screws into the holder without fabricating some more holes by drilling.
by:
The product is well built. Had to find my on nuts and bolts to fix it. It did not come with as the picture depicted. Overall a great product. Well still buy from Etrailer again.
by:
I have always been happy with the items from etrailer and intend to continue buying their products
by:
No complaints. Shipped faster than expected and everything was included.

I do not normally send reviews because i'm short on time but E trailer exceeds my OCD requirements, and the best thing is...I'm posting the same review for ALL of the products I ordered.

Thanks again.
by:
Appears heavier duty than past connectors I have been using.
by:
Good quality fast shipping
by:
Good rugged plug. Seems to be weather tight. Plug and play if you have the round end on your harness
by:
Good product but shipping is a little slow
by:
have not tried the product yet but it looks like a quality item. etrailer service is great and I will buy from them again............
by:
Worked fine, no problems at all!!!
by:
Nice, easy to install, all hardware and easy to use.
by:
Great product! Easy replacement of broken outlet!
by:
fit perfect / plug and play
by:
Site said it would fit my Cayenne. The mount bolt holes do not line up at all. Had to modify mount base to mount it.
by:
easy to install, worked perfect right off the bat. Bravo

  • 2018 VW Atlas 7-Pin Round Vehicle Connector and Brake Controller for Use w/ a 6-Way Adapter
    Thanks for the picture! It looks like your 2018 VW Atlas has been wired for a 7-way and has everything but the actual 7-way connector. To use the Hopkins Endurance Multi-Tow Trailer Connector Adapter - 7-Way to 6-Way, 5-Way or 4-Way item # HM47570 you will need the Hopkins Endurance Quick-Install 7-Way Trailer Connector item # HM40940. Both of these combined will give you a 6 pin round and a 4-pin flat connector. I have linked a review video that you will want to watch when connecting your...

  • Is 7-Way Plug of Hopkins Endurance 5th Wheel/Gooseneck Available Separately
    Hey Steve, Yep, you can absolutely get just the 7-way plug of the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # 41157. For that, all you need is the following: - Hopkins Endurance Quick-Install 7-Way Trailer Connector # HM40940

  • Mounting Hole Spacing For The Hopkins Endurance Quick-Install 7-Way Trailer Connector # HM40940
    Hey T, The mounting holes of the Hopkins Endurance Quick-Install 7-Way Trailer Connector # HM40940 are spaced 1-1/2" horizontally and 2-1/4" vertically. This would be a replacement for a factory Ford 7-way connector and would simply connect to the factory connector for a fast and easy install. If you need anything else just let me know below and I'd be happy to help.

  • Solution for Lost 7-Way Retaining Clip that Attaches to Socket
    The clip that you are referring to that holds the 7-way plug to the socket is typically found on the connector which is why the # HM40940 does not come with it. I wish we sold that piece by itself but only way to get it is to go with a new harness like part # PK11998 and you'd be set. I like where you mounted the 7-way too. A lot of factory 7-ways install in similar places which helps prevent accidental damage like the scenarios you described.

  • Replacement 7-Way For 2002 Dodge Ram 1500
    If your 2002 Dodge Ram 1500 has the harness with the round connector like the one in the attached photo, you may only need to replace the 7-way connector that is mounted on the bumper of your truck. I would recommend the Hopkins Endurance Quick-Install 7-Way Trailer Connector, part # HM40940. This would replace just the 7-way mounted on your bumper, and comes with the mounting screws. If you are wishing to replace the entire harness and the 7-way connector, the Hopkins Endurance Quick-Install...

  • How To Install 7-Way Connector On 2007 Ford F-250 With Factory 7-Way Cut Off
    We can definetly get you taken care of. You will need the Tow Ready Replacement 7-Way Harness and Socket for Factory Tow Package # 20147 and the Hopkins Endurance Quick-Install 7-Way Trailer Connector # HM40940. Since your 2007 Ford F-250 had a factory tow package harness you will just need to verify the functions of the factory harness wires and use the included heat shrink butt connectors to complete the installation. I highly recommend a circuit tester like # PTW2993 to test the function...

  • Availability Of 90 Degree 7 Way Plug That Can Be Re-Wired
    I do have a potential solution for you, but I am afraid we do not offer any kind of 90 degree adapter for a 7 pin plug. Something you could use is the Hopkins Endurance Quick-Install 7-Way Trailer Connector # HM40940 and the Universal Wiring Harness # HM40985. Technically this is not a 90 degree harness, but it could certainly still be used for that application, if you need a way to wire up a 7 way plug. I am sorry to say that we do not offer any 90 degree plugs that will fit your parameters.

  • Availability of U.S. Car Connector to Pigtail Wiring Harness and Compatible 7-Way
    Both the Hopkins Universal Wiring Harness # HM40985 and the Pollak Replacement Harness # PK11998 are 4-feet in length and provide a round U.S. Car type connector on one end and pigtail leads on the other. They are indeed interchangeable. I pulled one each of the two 7-way parts you referenced, parts # HM40940 and # PK11893, and measured their center-to-center mounting hole spacing. Part # HM40940 has 4 holes spaced 1-1/2-inches top to bottom and 2-1/4-inches side to side. Part # PK11893...

  • Recommended Wiring Harness for an In Bed 7-Way Connector on a 2000 Dodge Ram
    To add a 7-Way connector to the bed of your 2000 Dodge Ram 2500 you will need the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness item # HM42137. This harness puts a 7-way connector in the bed of your truck and allows you to keep the one on your bumper. This makes hooking up to your 5th wheel or gooseneck trailer easier and more convenient.

  • Is Hopkins 7-Way # HM40940 Direct Replacement for 7-Way Connector on 1999 Dodge Ram
    If your 1999 Dodge Ram Pickup has a 7-Way with a round U.S. Car Connector that plugs in to the rear of the 7-Way then it will be a simple matter to disconnect it from the existing one and connect it to the Hopkins Quick-Install # HM40940. The photo provided shows the back of a typical 7-Way with the U.S. Car Connector; this is what will mate with the existing harness connector. If your Ram does not have a round U.S. connector to plug in to the back of the 7-Way, but instead has a rectangular...

    Yes, there is! Since your Atlas has the US car connector or USCAR you can install the Replacement Custom Multi-Tow 7-Way and 4-Way Trailer Connectors item # 30955 and have both a 4-way connector and a 7-way connector if you ever need it. This way you won't have to use an adapter.

  • Does 7-Way of 2022 Ford Ranger Fit 7-Way of Casita
    The SAE number you listed J2863 is for a standard RV 7-way blade connector like what Casita would use for their trailer wiring connectors. We've not had any issues with the Ford 7-ways and the ones that would come on a Casita. If you ever needed a replacement on your Ranger the part # HM40940 would plug right into the connector on your vehicle. Or for a new harness and 7-way you'd want the part # C56431.
