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.

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 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.

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:

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.

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

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:

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:
2014 ChevroletSilverado

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.

  • Troubleshooting Trailer Brakes Engaging When Flasher/Hazard Lights Are Turned On
    In 7-way wiring the trailer brake circuit's contact/pin is next to the contact for the right turn/stop circuit. What can happen is that corrosion can build up on or inside either the truck socket or the trailer plug and this corrosive build-up can actually cause two adjacent circuits to become bridged together. If this happened between the right turn/stop circuit and the brake circuit applying your flashers would send a 12V signal to the brake circuit. Sometimes this corrosion (or trapped...

  • Replacement 7-Way for 2018 Ford F-150 and Airstream to Provide Tight Connection
    For a standard replacement 7-way for your 2018 Ford F-150 we have the Mighty Cord part # A10-7072VP which would easily install and give you a connector that would provide a solid connection. 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. Or if you wanted to just replace the connector you could use the part # PK12706. I would...

  • How To Know If Your F2018 Ford Escape Has A Factory Tow Package
    If your 2018 Ford Escape has a towing package you'll have a 4-pole or 7-pole connector already installed or a port to plug in a 7-way socket like part # A10-7072VP. If you don't see any wire harnesses already installed then you'll need to pick up one like the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118715. This would allow you to tow a small trailer without brakes. If you needed to be able to tow a trailer with brakes then you'd first install the # 118715 and...

  • Replacement Trailer Plug Door for T-One Vehicle Wiring Harness with 7-Way Trailer Connector

  • 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,...

  • Trailer Connector Recommendation and Install on 2020 Jeep Grand Cherokee
    Since your Grand Cherokee has the US car connector under and behind the rear bumper (see photo), you'll just need part # C55774 which installs as shown in the video I've linked. This connector provides both the 4-pole and the 7-way trailer connector. According to Curt, in some instances the vehicle's computer will need to be flashed at the dealership in order to fully activate the tow package. If your trailer has electric brakes and you want them to actuate you'll need a brake controller...

    First if you are using a connector like the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # 41157, try connecting to the bumper connection to determine if the Connector # A10-7072VP in the bed side is bad. You can also remove the additional harness by connecting the factory harness directly to the rear bumper connection to determine if the harness itself is bad. If those tests fail or you do not have the harness to begin with, you will want to remove the factory connector...

    Yes, the Hopkins 7-Way RV Style Connector part # H20046 and the Bargman 7-Way RV Style Connector part # WG54006-046 will both fit the same 7-way blade style RV trailer connector like the Replacement 7-Way RV-Style Trailer Connector part # A10-7072VP. The design of the the center pin is slightly different as your mentioned but this will have no effect whatsoever on it's compatibility. Therefore, so long as the 7-way has blade style pins which is standard for RV's then they can be swapped...

  • Turn Signals Do Not Work With Epicord 7-Way Molded Trailer Plug with Junction Box
    You do make sense but there is not a diagram showing the blade functions of the Epicord 7-Way Molded Trailer Plug with Junction Box # 277-000141 because it shows the wire colors by function. So the intention is to make it simple by showing you what wires on your trailer you need to connect to the junction box. While I do understand you thinking it may be the plug not matching up, that's highly unlikely. I know you said you checked your grounds but do the turn signal lights ground via...

  • 7-Way Wiring and Brake Controller for 2017 Chevrolet Express 3500 15 Passenger Van
    If your Express 3500's connector near the bumper resembles the round U.S. Car type connector in the photo I linked then this will be the trailer tow package connector you will use to plug in a 7-way trailer socket like # A10-7072VP or # HM40975. With or without the tow package wiring you can still install a 7-way using the kit # ETBC7 you referenced along with a 4-pole harness # 118392 which plugs in at the tail lights. This setup will be independent of any factory wiring and it will provide...

  • How to Prevent Corrosion & Replacementf 7-Way for 2015 Nissan Pathfinder
    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. You can also protect this 7-way and your connector from any future...

  • 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...

With you mentioning the connector only having 6 connector this tells me it is not for a 7-way and is used for something else. To install a 7-way you will need the 4-way # 118392 along with a 7-Way Install Kit # ETBC7. I have linked 2 installation videos below for the 4-way and 7-way.

If that's not there you could contact a Ford dealer to see about getting that intermediate harness you would be missing. Then you can use factory brake controller harnesses like what you referenced with the part # 3034-P with a controller like the # TK63VR.

    The first step would be to check your fuses to see if anything has gone bad. Next, if your fuses are good I recommend checking your wiring connection directly behind your 7-way trailer connection. The 1 o'clock pin position in that connector should show power when using a circuit tester like # PTW2993. If it is not hot in that position, then make sure you turn your key to ACC and try again. If that still doesn't work, then you will want to run a new wire using # 10-1-1 and circuit breaker...

  • Troubleshooting 7-way Installation That Blows 12V Power Fuse Without Trailer Connected
    The most likely cause for your Sienna to blow the fuse on your +12V auxiliary trailer power feed is a short somewhere in that circuit. The short could be caused by a wire that rubs on the frame and that has damage to its insulation or even by corrosion inside the 7-way trailer socket. If the wiring is new then it is more likely to be a short from a pinched wire but if the wiring has been in place on the Sienna for some years then it may be a corrosion issue.

  • Troubleshooting Trailer Running Lights Not Working on 2008 Ford Super Duty Truck
    The most likely reasons your trailer running light circuit isn't working is corrosion on the pins of the trailer connector or a blown fuse under the hood of your 2008 Ford Super duty truck. First try cleaning all of the pins on your 7-way with sandpaper to see if that allows the connection to be made and if that does not work try checking the fuses under the hood of the truck. If the 7-way of your truck looks pretty rough you might just replace it with the part # A10-7072VP.
