Video Transcript for Mighty Cord 7-Way RV Style Trailer Connector Installation

Speaker 1: Today, you're going to be taking a look at the Mighty Cord 7-Way RV-Style Trailer Connector for the trailer end, and that's gonna be part number A10-7081VP. So, here's what our 7-way plug is gonna look like. This is gonna make a great replacement if yours has gotten damaged or if you're upgrading to a 7-way round like we have here. Wiring it up is gonna be extremely easy. You're just gonna have to loosen up this one screw here, which will loosen up a little gate that's gonna make sure that our cable stays nice and tight in here and we don't pull on the connections. On top of that, we're gonna have this nice, little weather seal that's going to go around the cord.

It's gonna help keep out moisture and debris and make sure the inside of our connector doesn't have a corrosion build-up.Now, we're gonna have a small set screw on the other side that will allow the center section of the plug to come out and get us access to all the terminals on the back. Like most 7-way RV plugs, it is gonna have that little catch here. It's gonna make sure that it stays in position and that it's not gonna wiggle its way out. You just simply open the spring-loaded door. We're plugging into our tester here, so it's easier to see.

Then, the door's gonna have a little catch that's gonna go on the outside. That way, the plug can't accidentally be unplugged. You're gonna have to lift open the door, and then these two tabs here are gonna make it extremely easy to pull out.So now that we've seen the end result, let's show you how to wire it up. To begin, we're gonna strip back each one of our wires coming out of our 7-way. We'll just strip back a little bit from each one of our wires.

With each one of our wires stripped back, we can grab our plug, and at the back here, we'll notice that we're gonna have a Phillips screw. We're gonna want to loosen that up pretty good. You don't want to take that screw all the way out, but you want to make sure you loosen it up enough because it's gonna open up this gate that's on the end side.Then if we turn it over, right where that tab is, but towards the front of the plug, we'll have a very small flathead screw. We'll go ahead and pull that all the way out, and we're gonna be extra careful because these are very easy to lose just 'cause of how small they are. So, we'll go ahead and pull it out, and we'll set that screw aside.We're gonna take our bundle of wires.

Make sure they all fit inside the back. I'm actually gonna use my wires to push the end of the plug out. It may take a little bit of pressure, kind of wiggling it back and forth a little bit. And that center section here will come out.Once we have that out, if we need to, we can loosen this up more, so we can have more of our wires coming out the front so we can have better access to them. Now on the back of the plug, we're gonna have several screws that are in each one of these terminals. Now, they are labeled, and basically, all we need to do is go around loosening that screw and match up the color that's on the terminal with the color of the wire. I'm just gonna grab that small screwdriver, and we'll loosen up this one that says white. Again, you don't want to take the screw all the way out with the risk of potentially losing it. We're just gonna loosen it up a lot to where that terminal will open up. Give ourself a little bit of a gap there.We're gonna take our white wire and twist the end of it, so it keeps the wires together nice and neat. I'm just gonna put it in between the terminal and the inside. Just want to make sure you get all the wires in there. You don't have any stray, loose ones coming out of the edges 'cause we don't want to cause any kind of shorts if it we're to jump over. With our wire in, we can come back and make sure that screw's nice and tight, and it crimps down on that terminal, so we don't have to worry about the wire coming out. Now, we'll just go around. We'll connect all the remaining wires on the end of our terminal here.Once we have all the terminals in place, you want to make sure that you line up . there's gonna be a notch that's completely all the way through, and then on the plug itself, there's a small notch. On the other side, there is a notch, but you'll see that it doesn't go all the way through. The one that doesn't go the complete length of the plug needs to go to the side that has that set screw in it.It's gonna be a little bit of a tight fit just 'cause of all the wires in there, so you just want to be careful when you're putting it back, but you get it in the correct position so that everything lines up. Once we have the plug in place, we take that small set screw, and we can put it back in. We don't have to worry about the plug falling out or getting pushed out or anything else.We're gonna want to tighten down that Phillips screw at the back. That's gonna push down on that gate, and that's gonna keep the wires from getting pulled out or from pushing forward. If for any reason the wires here pulled, it will stop right here, so you don't have to worry about pulling out those connections.With the plug all wired up, I'm gonna plug it in my tester. Make sure all my lights and other functions are working properly. As you can see, my taillights are working as well as the left turn signal, brake lights, and the right turn signal. Now that everything's working properly, we're ready to hook up to our vehicle and hit the road. And that'll finish up your look at the Might Cord 7-Way Rv-Style Trailer Connector for the trailer end, part number A10-7081VP.

Exactly what I needed at a great price. 573832

- A10-7081VP

No surprises, which is always a good thing! Product was as advertised and it arrived timely. Looked at several 7 pin trailer to truck plugs and only this is the only one that had brass contacts that I cam accross. Just finished it yesterday, cutting off the old 2004 Toy Hauler cord connector and wired this one on with only a minor problem. There are two wires of the 7 that come to this connector that are of a heavier gauge (thicker) so getting them on under the wire clip took some finessing, but it all came together and works fine. YES I would buy this product again. 561192

I ordered all the parts required to safely flat tow out 2017 Jeep Cherokee Trailhawk from etrailer.com. The only part they didn't have was the Mopar Flat Tow Enhancement kit Jeep requires to flat tow this model. Ordering from them was great, the website is easy to use and I was able to locate all the pieces compatible with my specific vehicle. The expert recommendations help my decision choosing the right parts. I ordered from etrailer even though I found some of the parts on other websites a little cheaper. I chose to pay a little more because of all the effort etrailer has put into installation videos and guides. I was very pleasantly surprised to learn from etrailer that they have a price match guarantee! So my equipment consisted of the following Mopar Flat Tow Enhancement Kit (from Jeep) Roadmaster Battery Charge Line Kit for Towed Vehicles Mighty Cord 7-Way RV Style Trailer Connector - Trailer End WesBarg 7-Way, RV-Style Connector w/ 6' Long Coiled Cable Trailer End Pollak Black Plastic, 7-Pole, RV Blade-Style Trailer Socket - Vehicle End Hopkins Custom Tail Light Wiring Kit for Towed Vehicles SMI Stay-IN-Play DUO Supplemental Braking System Roadmaster Brake-Lite Relay Kit for Towed Vehicles Blue Ox Alpha Tow Bar - Motor Home Mount - 6,500 lbs Blue Ox Base Plate Kit - Removable Arms Blue Ox Tow Bar Cover - Aladdin, Aventa LX, Aventa II The installation videos are great but not all inclusive. Take the time to read the instructions that come with the parts. This is a major project, I took about 30 hrs over a full week but as you'll see in the pictures I took s few extra steps to make a cleaner look. Some of those extra steps: The base plate install requires the bumper be modified cutting off a flange on each side, I spray painted this to prevent corrosion. In the install video of the baseplate on the drivers side they use an extra quick link (not included) to run the safety cable around the wiper fluid reservoir. I took the time to remove it and run the safety cable behind it. I didn't want our nice new vehicle to look like it can be towed so I played the brake away switch and 7 way trailer plug behind the license plate, so when not being towed our vehicle looks great! Some things to be aware of. The Brake air cylinder that mounts to the brake pedal with four bolts may need longer bolts, it did on our Jeep. Spend the money for weather tight heat shrink crimp fittings. The Hopkins wire harness was about 1.5 feet short to get to my plug location. Buy extra zip ties, electrical tape and split loom. I recommend reading all the various installation manuals and watching all the videos because the various components integrate together and if you install one at a time you'll be doing a bunch of extra work. The brake light relay is a real pain in the butt, not because of the hardware but because of the location of the brake light switch which is very hard to get to. Overall I am very happy with the products and how the installation looks. We haven't towed it yet but do not expect any problems. 413528

Still very happy with our purchase. We’ve towed over 10k miles and have had zero issues with our tow setup. I’ve shared my experience with several other RVrs and recommended your company for their needs. Thank you

Product is adaptable to my needs, utility trailer rather than RV. 362589

- A10-7081VP

No instructions with this product. Took a bit of luck to get it apart - removed the small set screw, then plugged it into the towing vehicle - then pulled the shell off. Finally figured it all out. The plug works on my Travel Trailer. 358178

- A10-7081VP

Does not fit snug in plugs which makes for a poor connection 334831

- A10-7081VP

My camper trailer connector was having a poor connection on the brake terminal, giving me a "Check Trailer Brakes" light on my truck instrument panel and no brakes at the trailer. This will solve that problem by providing a tighter connection. Nice solid construction. Easy to install on camper shore power cord. 324068

Still working good when I traded my camper for a newer model this past September. Will look to etrailer the next time I need a product for my trailer. Very easy to install.

Don't let their color coding throw you as you will need to wire based on functions and pin locations.

  • Replacement 7-Way and Lead Recommendation for Trailer with Melted Wiring
    Since you have some wiring that melted a 7-way with a plug and lead like the part # A10-7W6 would be a great choice. Or to make the install even easier we have a 7-way with a junction box part # e99011 that you can take your old wiring and connect to a box instead of to lose wiring for a much more secure and easier install. I am not totally sure what you mean by the connection bars but the parts I mentioned are sealed connectors.

  • Adding 2nd 7-Way to 2019 Ford F-250 to Provide 12V Charging Power for Trolling Motor
    The 7-way wiring harness setup in your F-250 that will connect to the camper (or to a trailer with a 7-way hookup) does include a 12V auxiliary power circuit that can maintain the deep-cycle batteries that come with the camper. This 12V power circuit is carried on the contact at the 1:00 position, as shown in the included photo. Attwood trolling motors are offered in 12V, 24V and 36V versions and for charging a 12V model you can add a second 7-way socket (just like the one in the truck)...

  • Converting 6-Way of Trailer to 7-Way to Connect to 2003 GMC Sierra 2500HD
    Whenever possible I recommend avoiding adapters if they aren't needed as it's another connection point that can cause issues. Since the 7-way connector is much more common than the 6-way I would recommend replacing the 6-way on your trailer with a 7-way that matches your vehicle directly. Easy solution for that is the part # A10-7081VP. I attached a diagram for 7-ways for you to check out as well as one for a 6-way to help make the transition easy.

  • Does Travel Trailer Battery Connector Need to Have Ground Connection
    Yes, whether you plan on using the Pollak Single-Pole # PK11852 (which is geared more towards winches) or the Mighty Cord 7-Way RV Style Trailer Connector # A10-7081VP (which is recommended for a travel trailer), you will not only connect the power wire but you also need to have a ground connection as well. The single pole connector has a ground connection on top of it while the 7-Way has a pin designated for the ground (see attached picture).

  • Replacement 7-Way Plug and Cable for Hayes Sway Master Electronic Sway Control System
    A replacement 7-way plug and cable for the Hayes Sway Master Electronic Sway Control System is not offered. My contact at Hayes confirmed that the 7-way cable is hard-wired inside the control box and that no replacement part is offered. If the cable is still good and you need only the 7-way plug we do offer parts that will work for you. You can use Optronics 7-Way Round RV Style Trailer Connector # A7WCB or the Mighty Cord part # A10-7081VP.
