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.

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

We do offer a 7-way connector that twists into place, part # HM40920.

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:

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.



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



by:
2014 Chevrolet Silverado

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.



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

Perfect match plug and play for a 2015 Chevrolet Silverado 3500 HD Duramax. 10 minute install. It would have been 5 stars if it were more of a snug fit into your receptacle. I would recommend.



by:

This Mighty Cord 7-way connector was an exact replacement. I received the part very quick and installation was easy and took all of 3 minutes...just plug and play.

Just the right configuration I needed. Works for all the vehicles that I tow. Good construction.

  • Camper Electric Brakes Go Out When Pressing Brakes
    It's probably the wiring to the brakes having a short, but there are a number of things you should test to find out for sure. First test the brake controller, and to do so sever the blue wire a couple inches from the back of your controller. Then use circuit tester # PTW2979 to test the end of the blue wire coming out of the controller. It should only have power when you apply the manual override; if it shows power at idle then there is an issue with the controller and it will need to be...

  • Replacement Trailer Wiring 7-Way that Fits 2006 Ford E-350 Van
    Sounds like you have a standard round trailer wiring connector present on your 2006 Ford E-350 which we have 7-ways that fit like the Mighty Cord # A10-7072VP. As far as something that will fit through our van's bumper and can be sealed I am not totally sure this is what you are looking for but it will work as a 7-way.

Vehicles like yours with the 7-Way tow package have the blue output brake wire already ran from the back to the front. It is located under the dash near the emergency brake pedal.

  • Which Trailer Wiring Harness for 2019 Nissan Pathfinder
    The harness you need will depend on whether you're wanting a 4 pole or a 7-way trailer connector. I'd recommend using part # 118273 which provides a 7-way, that way you could use it with an adapter like # PK12716 and be covered for the 2 most commonly found trailer connectors. The # 118273 includes the trailer connector, the wiring harness, the jumper harness and the relays needed to activate the tow package on your Pathfinder. If your hitch has a tab on it for attaching a mounting bracket,...

  • Troubleshooting 'Trailer Disconnected' Error Message on 2016 Ram 3500 Dash Display
    If your Ram's dashboard display is telling you your trailer is disconnected, and this message comes on and goes off as you drive, the issue is most likely to be corrosion in either the vehicle socket and/or the trailer plug. Something is interrupting the connection of the trailer brake circuit and this is generating the error messages. Please refer to the linked photo to see the trailer plug contact that handles the brake circuit. Inspect both the vehicle socket and trailer plug for signs...

  • 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...

  • Will Mighty Cord 7-Way Connector # A10-7072VP Fit 2017 Jeep Grand Cherokee W/ Factory Tow Package?
    Since your 2017 Jeep Grand Cherokee has the factory tow package and a 7-way connector you can absolutely use the Mighty Cord Replacement 7-Way RV Style Trailer Connector for Factory Tow Package # A10-7072VP as a replacement. The factory wiring connector will plug into the back of the connector, and then the front side with the cover is where the 7-way trailer connector will plug in to.

  • Troubleshooting Issues with 2012 VW Touareg 7 Pin Trailer Connector
    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...

  • Replacing 6-Way of 2014 Chevy Silverado for 7-way
    From the factory your 2014 Chevy Silverado should have came with a factory 7-way and not a 6-way so most likely your 7-way was swapped out for a 6-way. To then swap a 7-way back in we have the # A10-7072VP listed as a fit or if you want the style of 7-way and 4-way like a lot of Silverados came with you'd want the part # HM40975.

    There isn't a specific reason why corrosion has built up on just one pin of your 2015 Nissan Pathfinder's 7-way, and this can unfortunately be a common occurrence. Moisture and dirt particles build up and create the corrosion, and it just so happened to be on this one pin. The good news is, you can replace just the 7-way connector with the Replacement 7-Way # A10-7072VP. This will plug right in without any issue whatsoever.
