GMC Acadia

I ordered this when none of the lights would work on all three trailers I owned. After replacing the fuse and checking everything else it came down to this. It was a perfect fit and super easy to install. The wiring harness for my acadia is a plug and play so no splicing or sodering. I would highly recommend this product.

2018 Dodge Ram Pickup

The 7-Way RV Style Trailer Connector for Factory Tow Package shipped quickly and fit perfectly in my RAM 2500 diesel bed. It was difficult to install only because the hole in the bed wall was rather tight so I had a difficult time pulling the cable into the bed to plug the replacement part in (no fault of the part). The Etrailer-provided part seems to be made of a much better/durable plastic than the one that needed replaced. The part that it replaced was cracked/broken in 2 places around the border including at one of the mount screws due to hard/brittle plastic. All the electrical connections work perfectly. Only improvement I would recommend is send replacement screws with the part--Luckily the screws were still in place, even at the one mounting hole that was broken. I was unable to find the correct replacement part at several other online sites. The brief instructional video on ETrailer.com was also very helpful.

This worked awesome, I purchased the three way truck bed harness for my gooseneck and replaced the rear main
7 way at the same time.
E trailer shipped it quickly and there website pictures and instructions where great for the installation.

I have to say that I've used Etrailer for all my trailer needs and have been so overwhelmed at the price and the product .. I'll never shop any other place .. why .. no one has ever come close to the savings I found here .. I bought my heavy hitch from here and couldn't be happier and this item was the perfect match to what I needed .. Thanks Etrailer !



by:

Fits if you want a gap in the factory bumper. Does not fit like factory connector.

I was so dissatisfied with customer service I kept the plug, and will not order from Etrailer again.



by:

I received the wrong part based on your recommendation. Here’s my exchange with your customer service rep :
Good Morning,

Thank you for clarifying.

Based on the item you want to return from your order, the return cost is greater than the part. Therefore, it would not be cost effective to return these items. I recommend selling locally to make your money back.

If you have any questions or concerns please let me know.

Thank you,

Tiffany H.

Well, Tiffany, this is a good lesson for me. I buy a part from your company solely based on the recommendation of your representative. It arrives and it’s the wrong part. And I have no recourse. Not even an offer for a credit nor an offer to send the correct part. A complete waste of my time and money. Didn’t even receive an apology. Caveat emptor. Well, the lesson is learned. I will never do business with etrailer again. I will never recommend etrailer to my friends. And I will take every opportunity to disparage your company.

It fit in my 2019 Volkswagen Atlas. I have yet to hook up to a trailer, but being an exact fit I do not expect an issue.

I had to put in my information on my truck and the plug I received was not the factory one. Had to drill holes instead of just the twist out plug that comes in a Silverado

Thank you for sharing. I researched 7 way connectors for a 2004 Chevy and found that part # PK11916 is a better option for a twist in plug replacement. It will fit with 2007 - 2013 ChevroletGMC 1500 trucks and 2007 - 2014 ChevroletGMC 25003500 trucks.

Works fine. However I had to drill holes for screws to hold the connector in place. The original was just twisted in place.

No problems. Working as good as the original



by:

Fit perfectly into place on my fifth wheel 7-way extension into the bed of my truck. The previous bracket broke and the trailer brakes quit making contact. This was the same as the broken one, and fit up perfectly and all contacts are working. I gave it a rating of four because the previous one (which was the same) broke after about 3 years of use.



by:

Product worked well and we actually mounted not in the provided location in hitch but we but the housing wheeler you can mount it on the top of the hitch. This product has been working well for us and recommend to all. It worked well in our 2915 Pathfinder

Harness fit perfectly. Shipping fast. Very happy.



by:

Wow great job to all, what service and the hitch, the plug for the lights, and the license plate holder, is all you said, and it took less than 15 min to install everything. What your company is doing right now, document , train and continue to do it, you have made this customer very happy and we will do business again! Sorry no pics because its hiding behind the roll pan just like you said it would!

Thanks

Wiring portion is direct fit to 14 Silverado. Since i replaced factory plug had to drill new holes and filled original hole with cut to fit scrap plastic.

Good product but mine broke in the winter. Cover broke off just before leaving in a trip so had to get one shipped fast. Cover hold male plug in. Wish they could make one that would stand up in cold temps

  • Replacement 7-Way Mounting Bracket Solution for 2012 Chevy Tahoe
    Hey John, so the factory 7-way mounting bracket of a 2012 Chevy Tahoe would have been built into the rear bumper so if that's rusted away what you'd need to do is use a bracket like the part # PK12711U which attaches to the lower rear bumper edge and has the universal 7-way mounting bolt pattern. If your 7-way mounts using a twist lock style attachment you'd also need to replace it with the part # A10-7072VP.

  • Troubleshooting Right Trailer Brake Light & Trailer Brake Controller Not Working
    Thanks for providing the details on your trailer wiring issue. Since you have three trailers that all show the same issue when connected to your 2004 Chevrolet Silverado odds are good that the problem is in the truck wiring. The first thing to check is the ground connection on the vehicle wiring harness. This wire's ring terminal must make a clean metal-to-metal connection in order to allow for all functions to operate properly. Corrosion can build up and cause issues. Try removing the...

  • Replacement 7-Way and Bracket for 2001 GMC Sierra 1500
    The Hopkins Endurance Twist Mount 7-Way RV Trailer Connector # HM40930 is designed specifically to mount (and twist) into the factory bracket for your GMC Sierra. Unfortunately this style bracket is not available as an aftermarket part. You may be able to contact your local GMC dealer to see if they have this part available but if not your best option will be to use a standard 7-Way and bracket as a replacement. For this I recommend the Mighty Cord 7-Way # A10-7072VP along with the Mounting...

  • Adding a 7-Way Trailer Connector to a 2016 Chevrolet Express 3500 Van
    We don't have a 7-way to plug directly into the van but I do have an option for you. If your 2016 Chevrolet Express 3500 van had a factory 7-way and it needs to be replaced you can wire in a new one with a harness like # PK11998 and then connect it to a 7-way connector like # A10-7072VP or # HM40975. If there is currently no trailer connector at all you will first need to install a 4-way connector, # 31345. Once you have the 4-way you can use our # ETBC7 kit for a fully functioning 7-way....

  • Determining if 2019 Chevy Express Van has Tow Package for Installing Trailer Wiring
    If your 2019 Chevy Express Van 3500 has the tow package there will be a round connector taped behind the rear bumper that a 7-way like the part # A10-7072VP could attach to. Otherwise you'd need to install a 4-way first like the part # 118392.

  • Replacement 7-Way Options for a 2002 Ford F-150
    You may want to start off by seeing if your 7-Way is connected to a US car connector. If that is the case then I recommend removing your 7-Way and, using a Circuit Tester like part # PTW2992, testing the pins on the car connector. If those pins are sending signals then you may just need to replace your actual 7-Way connector with part # A10-7072VP. If the US car connector is not getting signals then you can check out the attached installation video of the Ford Replacement OEM Tow Package...

To do a replacement 7-way on your Airstream you could go with the kit part # e99011 which comes with a junction box that you would mount on your trailer frame and a 7-way we know fits the 7-way I mentioned.

  • Replacement OEM 7-Way Connector w/ a 4-Way
    Yes, you can. Both the Curt T-Connector item # C55774 and the Mighty Cord Replacement 7-Way item # A10-7072VP use the USCAR 7-way socket. These are what every vehicle that comes from the factory with a 7-way connector has. Since your 2023 GMC Canyon came from the factory with a 7-way connector, you can use the Curt item # C55774 to replace your broken one. This will provide you with both a 7-way and a 4-way. I have linked an installation video below.

  • Troubleshooting Trailer Running Lamps that Flicker When Parked
    All the # C35FR adapter does is add a little bit of a load to the lighting circuits to prevent the bulb-out light or warning from going off, it won't solve the issue you describe. What could be happening is that the trailer connector on the vehicle or on the trailer has some corrosion built up on the pins/sockets that power the 12-v circuit and the running lamp circuit which would make sense as the pins are adjacent in the trailer connector. At a certain point once the corrosion gets severe...

    GM actually uses the # HM40975 as the OEM trailer connector, so that's what I'd recommend you use. The connector will plug into the socket located above the spare tire. You'll need to free the connector from the frame member and uncoil it so it will reach the rear bumper. The truck is indeed pre-wired for a brake controller. To complete the installation, you'll need brake controller and the vehicle-specific wiring harness. I'd highly recommend the Tekonsh P3, part # 90195. The P3...

    If your trailer or tester utilize LED lights that is likely the issue. The factory 7-way on your 2012 VW Touareg wasn't designed to function with LED's without the adapter # C57003 which has integrated load resistors to allow LED's to not trigger lamp out sensors. This also helps with the emergency flashers. If your trailer and tester are not LED, then you may have an internal issue with your 7-way and you can use either # A10-7072VP or # HM40975 to replace it. Before replacing, I...
