Product was delivered in a timely manner. They were easy to install and fit my 2015 Jeep Wrangler perfectly. All pieces were reasonably priced and less expensive than if purchased separately.



Great! They are wearing very well and continue to work as designed.




Looked appropriate but was not needed, as it turned out I needed a 2 into 1 converter for the motor home which I ordered from etrailer, so I returned this item.


This item was a replacement for the Roadmaster that was out of stock. It was less expensive and seems to work just fine connecting the toad and mh. At this point I am very satisfied with the service and the product.



In use for ten thousand miles and still working out. Great product. No issues


works great, no problems so far. its ice i can look out back window and see the plug is glowing so i know my lights are working.



works great, I can look out rear camera at night and see plug glowing.


I'am in the process of setting up my 2017 Equinox to tow behind our motorhome. I've placed 4-orders with etrailer. So far I've installed the base plate, the wiring from the rear tail lights to the front end.I also received my Tow bar and the quick release parts. my next project is to install the invisi brake system. I want to send Kudos to Cathy T for her help and her great customer service. I'am also thanking James A for his quick response to a question about the wiring harness. I'am extremely happy with the quality of everything I ordered at etrailer. Thanks


I open the package and all looks correct, have not yet installed on Jeep
Again Great service from Etrailer!!



Great product no issues. Used for over a year.


All of the products I have purchased were perfect. The shipping was right on time. I have told several of my friends and acquaintances about


Product looks really good, just wish it was a foot longer. I haven't tried it yet.
I hope it doesn't pull out when making turns.
I'm using it on my Saturn toad car, behind my class C fleetwood motor home.

It works great after a year of use. Would have liked the cord to be about a foot longer. Well worth the cost and excellent construction with sealed ends. The cord did come out one time while towing.


Great quality component! Fast shipping excellent people to deal with helpful and courteous. Will be purchasing from them again!! Thank you.


Seems to be a sturdy product. We'll see how it performs after 5 months on the road. Thanks, etrailer, for the affordable options compared to my local RV stores.



Went through a long hot summer of use without fail. Looks like it will last a lot longer.


Etrailer's Customer Service was second to none. Extremely happy will the product, step by step videos, and quality of service. Couldn't have made it any easier. I will suggest to friends and return for additional products.


You can't go wrong with products from
great products, great prices, great communications and FAST shipping. A very satisfied customer, who'll return.


The adapter cable worked great and eliminated two other adapters that I hd previously been using to connect the RV to my Saturn SW


This product was an easy installation and of quality construction. Thanks George of Etrailer...


The product looks very good quality but i think it is actually for a travel trailer and i bought it thinking it was for a motorhome and a dingy.


This looks pretty good, again I haven't had a chance to install it yet, but I'm sure it'll work fine. Maybe I'll report back once I have it installed and working.

Paul M.


Works and looks great! A very good high quality product and would certainly buy again.


Worked perfect!



Could not be more satisfied! Will be ordering a rear hitch for a Fiat 500L later this year to install on my daughters car. Thanks for your great products and service!


Product is good, would rate higher, but it seems to stretch out and then when unplugged does no curl back up like my older cord did. Everything else is great.


This is a great place to buy if you have a problem they will help . They try to save you money ,and also keep track of your shipments.


Product that I received was as advertised, shipping time was good .overall very happy with product and website, will definitely order from them again and will recommend this site to friends.


Great product I have been using this type cord on my boats for a decade.


Great unit. Met my expectations. Just a long drive to pickup. Found out on arrival I could have picked up out of Texas


Secure and safe. Meets all our needs.


Can not be rewired if ever needed, other than as t it's an alright product.

  • Recommended 4-Way Connection Between Towed Vehicle and Motorhome
    The only real advantage of the 4 round over the 4 flat trailer connector is the clean look of the connection point and the protection from elements when not in use. For instance the Pollak Heavy-Duty, 4-Pole, Round Pin Socket, Concealed Terminals - Chrome - Vehicle End # PK11410 has a clean finished look on the front of a towed vehicle and will protect the connection from dirt and debris with the spring loaded cover. Many people like the connection between the motorhome using a harness...

  • Availability of Tow Bar Umbilical Style Adapter to Go From 4-Way Flat to 7-Way Blade
    Yes, for a tow bar umbilical extension adapter to go between the 4-way flat of the part # HM56304 and a 7-way socket you'd want the Wesbar adapter part # 787196. This has a 5-way flat on one end and a 7-way blade connector on other. The difference between a 5-way and a 4-way is just the extra pin on the outside of the connector. This pin would simply be left off when used with a 4-way. I attached a link to a video for this adapter that shows it in use for you to check out as well.

  • Does the Blue Ox Tail Light Wiring Kit with Block Diode # BX8811 Come With a 4-Way Connector
    The Blue Ox Tail Light Wiring Kit with Block Diode # BX8811 that you referenced does not come with a 4-Way connector as you stated. To add a 4-Way connector you can simply use the Hopkins Wiring Harness with 4-Pole Flat Trailer Connector # HM38138 and connect it to your current wiring using Butt Connectors # DW05744-5. For a look that is a little more clean and will provide you with a 7-Way to connect to your RV you can use the Hopkins Nite-Glow Tow Bar Extension Cord w/ Socket - Coiled...

  • Availability of 8 Foot Flat Towing Umbilical with 7-Way on One End and 4-Pole Flat on the Other
    There's not an available 7-way to 4-pole flat umbilical like what you're looking for, but I do have some easy solutions for you. The Hopkins Nite-Glow 7-way to 5-way flat coiled adapter, part # HM47025 will work with either a 4-pole or a 5-pole trailer connector. It would plug right into the connector at the front of the towed vehicle provided by the Hopkins Towed Vehicle Wiring Harness you referenced, part # HM56302. If the unused socket bothered you, you could cover it with a small piece...

  • Towed Vehicle Wiring and Wiring Extension Recommendation for 2013 Honda CR-V
    The tow bar wiring I recommend for your 2013 Honda CR-V is the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56304. This is a custom-fit wiring harness that will plug into your vehicle wiring behind the taillights. I recommend this kit because of the ease of installation and the fact that the harness will prevent electrical feedback to protect your CR-V's electrical system. I have attached an installation video of this wiring harness on a similar vehicle as yours. You are...

  • Coiled 7-Way to 4-Way Round Adapter Recommendation
    Sounds like you are looking for the Hopkins Endurance Flex-Coil part # HM47043 which will plug a 7-way blade to a 4-way round connector. Or if you need the 4-way round socket as well you'd need the part # HM47044.

  • Parts Needed to Flat Tow 2006 Jeep Grand-Cherokee Behind RV
    Safe and legal flat towing of a vehicle behind a RV requires a number of components. A tow bar, safety cables, a wiring/lighting kit, base plates and a braking system for the towed car are essential items; a high/low hitch adapter and wiring extension are also often required. The linked article covers each of these in detail and this is a great place to start getting familiar with the requirements. For base plates I recommend the Blue Ox # BX1123 which will fit your Grand Cherokee as long...

  • Parts Needed to Flat Tow a 2017 GMC Yukon SLT with Blue Ox Base Plate Kit
    Yes, you can use the Blue Ox Base Plate Kit # BX1718 to flat tow your 2017 GMC Yukon SLT 4WD as long as it has the Adaptive Cruise Control. If you don't have the Adaptive Cruise Control then you'll use the Blue Ox Base Plate Kit # BX1716 instead. For a complete flat towing setup you will need a base plate kit, tow bar, safety cables, vehicle tow bar wiring, a supplemental braking system, and possibly a high-low adapter. I recommend using the Blue Ox Alpha 2 Tow Bar # BX7380 because it...

  • Wiring Harness to Flat Tow a 2015 Ford F-150 EcoBoost Behind a Motor Home
    Hopkins shows tail light wiring kit for towed vehicles # HM56009 as the correct option for your 2015 Ford F-150 EcoBoost. There isn't any other plug and play type of harness available for your F-150. I have included a link to a video review of this harness for you. There is a 4-Way flat on the end and since most RVs have a 7-Way connector you could use kit # HM47044 and replace the 4-Way flat with the included 4-Way round.

  • Hopkins Nite-Glow Tow Bar Extension Cord w/ Socket Recommendation for RV Towing Vehicle
    Sounds like your dinghy vehicle is getting corrosion in it's tow bar lighting connector from driving the vehicle in inclement weather. If you wanted to go with the kit part # HM47044 that would be a great solution to give you a new umbilical from the tow vehicle to the dinghy and a new 4-way for the dinghy as well. If you can I would try to mount the 4-way out of the direct path of possible rain or spray from other vehicles.

  • 7-Pole To 4-Pole Trailer Connector Adapter To Flat Tow 1997 Suzuki Sidekick
    From your photos you have a 7-blade connector on the RexAir and a 4 pin round connector on the 1997 Suzuki Sidekick. The blue wire in your photos is a 4 pin to 4 pin connector which will not work to connect the RV and the Suzuki. All you need is a 7-pole to 4-pole adapter part # HM47043 to connect the RV to the Suzuki.

  • Availability of Coiled 4-Way to 7-Way Cable for Flat Towing
    Just the coiled cable from the Roadmaster Flexo-Coil Wiring Kit # RM-15247 is found as part # RM-164-7 on our site. Pretty much all of the "cable only" kits come with the socket and bracket for the towed vehicle side like what you see with this kit. For something a little more cost-effective I recommend going with the Hopkins Nite-Glow # HM47044 instead. This is the exact same thing just from Hopkins instead of Roadmaster. Hopkins is one of the leading wiring manufacturers on the market...
