Received what I ordered and on time.


I ordered all the parts required to safely flat tow out 2017 Jeep Cherokee Trailhawk from 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.

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

Trailer connectors were easy to wire and works great. Thanks etrailer for a great product and fast shipping. Your No. 1


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.

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.

Looks like good part. Been needing a new connector for a long time.

A year later and still working fine.
Richard K - 08/13/2021


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.


Parts came quick and easy,wired up back up lights for plow trucks, great product easy to use and put together. Ordering from etrailer was quick n easy. Parts came 4 days after my order.

Item was a perfect fit to the vehicle, delivery was fast and price was fine. What else
could one ask for? As always etrailer is the best!

Albert - 08/18/2020


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.


Never been disappointed with anything from etrailer. Service is second to none


It works as advertised. If you need a replacement it is a good product.


Quality plug at an excellent price. Etrailer is the place to shop for towing accessories.


Easy to assemble. Exactly as shown in the video. Easy to order. Delivered quickly despite ground delivery. etrailer is one of the good ones.


It's a trailer plug. It does exactly what you imagine it to.


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


works but corrodes too quickly. cheaply made

zenaida - 04/19/2020


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


The set screw, holding the plug together is weak it will strip out easy.


Works well but needs a better strain re lief.........


No issues with install or use.


Exactly what I needed at a great price.


Works as expected



everything good

  • Troubleshooting 5 Wire Functions for 7-Way Trailer Connector
    The Mighty Cord 7-Way RV Style Trailer Connector - Trailer End # A10-7081VP you asked from will have the function locations that will match the attached photo. Don't let their color coding throw you as you will need to wire based on functions and pin locations. Here is how to determine which wire goes can simply use a battery and some wires to test functions with the 12V power for testing each light function and the negative battery terminal connected to ground on your trailer...

  • 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).

  • 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.

  • 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.

  • 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.

  • 10' Long 7-Way Cable With Double Ended Trailer End Connectors
    I have a couple options for you as we do not have the Bargman 7-Way Molded Trailer Wire Connector # 50-67-210 in a 10' length. First you can take a 7-Way Molded Connector w/ 10' Cable # 50-67-005 and add a 7-Way RV Style Trailer Connector # A10-7081VP. Or you can connect 2 Hopkins 7-Way RV Style Connector w/ Molded Cables # HM20086 together if you prefer to have the molded and sealed ends.

  • 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)...
