Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter w/ 4-Way Vehicle End Plug - HM47180

Average Customer Rating:  4.8 out of 5 stars   (44 Customer Reviews)

Adapt a 4-way flat to a 7-way RV-style socket while still retaining use of the 4-way. Or simply replace a damaged 7-way connector. Plug into tow package for 7-way, or plug into existing 4-way and hardwire into vehicle to get additional functions.

by:

Got this to replace the poorly constructed plug that came with the 7pin wiring kit. That plug broke at the spring hinge the second time I used it.
Surprised that Hopkins didn’t include “Butt Connectors” though. Seems a little nickel dimeish.
Had a good experience with Paul who refunded their price for the defective Kit plug as well as refunding the price difference for the wiring kit which had gone from $110 to $48. Overpriced to begin with but convenient.
Paul did real good dealing with a pissed off Old Guy




by:

I just got it a few days ago and it is not installed. But, it came with mounting hardware and bracket, so that is nice. The wire harness also plugs into the main body which is also a nice feature. I also like that it has a secondary 4 pole socket directly below the 7 pole in case you are pulling a utility trailer without brakes. Build quality seems good. It is all plastic, but doesn't seem flimsy at all. I would recommend this product.

Note that a 7 pole has extra circuits for:
1. charging rv or trailer brake battery
2. rv or trailer brakes
3. backup lights (center pole and purple wire)


Comments
This receptacle was easy to install and has worked great. No problems at all.
Brian - 07/18/2021


by:

Really easy to install. Plugs right in to the flat four wiring. I found a decent spot to mount the bracket and finished the installation. 5 minutes max. At this time I didn’t have to wire up a brake controller. That’s going to be a project for a different time. I would definitely recommend this product.




by:

Sent in a timely manner and product is perfect.




by:

Perfect for connecting the tail lights from my RV to my car on the car dolly.




by:

Working great




by:

This, and everything else I ordered from etrailer came without a hitch. They also provided great customer service, answering my question about another product in a timely and complete way.




by:

Perfect fit with factory wiring harness connector.




by:

This product was installed on my Lexus RX350. I had the dealer perform the installation.

The Service department appreciated the direct connectivity to the existing trailer wire. We added a connection to a 12 volt source.

It was placed directly on the lower part of the bumper. Looks Great and works correctly.




by:

Everything I have ordered from etrailer has been quality products. I especially like the installation videos which are a great help. It's great they give you frequent updates by e-mail about the status of your order and shipping has been really fast.




by:

I had to do a little figuring of where I wanted to put it and how to install it on the car, but ultimately it is working fine. The bracket is a little flimsy but if you push it forward with your other hand when putting in the connector it works fine.




by:

The connector is made of high grade material and was engineered very nicely. This was an easy installation as well. The connector was found to be a reliable device and made us feel safe while pulling our equipment.




by:

good service and quick delivery.




by:

Great product for hooking up my camper and or trailer with no problems to my 2007 jeep liberty. Recommend this product for people who want do the same.




by:

Good quality easy install




by:

Easy to install, this kit was a breeze. I do wish that the install instructions were more informative but that's no biggie if you know your way around a vehicle.




by:

Product arrived in a timely fashion with no surprises! Seems like a quality product but unhappy that I can't buy an American made product even at a
Premium price! Only time will tell how durable the product will be




by:

It's working good and I like it.




by:

Better product than expected. Just what the Trailer Doctor Ordered. Thanks.




by:

Produce is good. I have to redo my connection to match plug.




by:

As always great products , fast shippin g!!

  • Adapter Needed To Keep 4 Pin Functions While Connecting to a 7-Way Trailer.
    The Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter w/ 4-Way Vehicle End Plug Item # HM47180 is the product that you need to connect to the 7-pin flat connector on you trailer. This part will allow the basic light functions of a 4 pin, while having a 7 way connection for your trailer. This should be a simple install. This wiring harness plugs into your existing 4-way flat connector. Since you wont need the additional functions of the 7-way you don't need to connect...

  • Will Hopkins Endurance 4-Way to 7-Way Adapter Fit Factory Mounting Holes on 2002 Dodge Ram 1500
    The mounting hole spacing on the body of 7-Way adapter # HM47180 is 1-1/2 inches on center top to bottom and 2-1/4 inches on center left to right. Compare that to the hole spacing on your 2002 Dodge Ram 1500 to determine if it is a direct fit. If it is not a direct fit you can use the included mounting bracket to mount the connector in an alternate location.

  • Installing Hopkins 4-Way to 7-Way Trailer Adapter for Just 4-Way Functions
    When using a trailer connecter like the Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter w/ 4-Way Vehicle End Plug # HM47180 you will need to ground the white wire to your vehicle to make sure the trailer connector works correctly. You want to attach that ring terminal to a bare metal connection on your frame. This will allow your 4-way functions to transfer to the 7-way blades correctly.

  • Does Hopkins 4-Way to 7-Way HM47180 Fit 2011 Chevy Traverse
    The Hopkins 4-way to 7-way adapter part # HM47180 will convert your 4-way to a 7-way like you are needing and would work great. It also has a separate 4-way that mounts below the 7-way so you wouldn't lose that function either. Basically it just plugs right into your 4-way and it's ready to be used.

  • Where Do Vehicle and Trailer Wiring Harness Ground Wires Connect
    The ground wire on a trailer's wiring harness (usually a white wire) should be firmly attached to clean bare metal on the trailer frame. The white ground wire on the vehicle's wiring harness should similarly be attached to clean bare metal on the vehicle, or to an existing factory grounding point, or even directly to the battery negative terminal. When the trailer and vehicle are connected together through their 4-pole wiring the trailer will ultimately be grounded to the vehicle battery. Bad...

  • Difference Between 4-Pole to 7-way Wiring Adapters 47180 and 37185
    Hopkins part # HM47180 is a 4-pole-to-7-way wiring adapter that is equivalent to the similar # 37185. The only real functional difference between them is that on part # 37185 the 4-pole trailer connector is located to the side of the 7-way, rather than under it as with # HM47180. Both adapters plug in at an existing 4-pole vehicle connector and re-format those lighting signals to the 7-way configuration. The 7-way can be wired, if desired, to add new functions by using the included pigtail...

  • What Wiring Harness Do You Recommend For My 2021 Lexus RX 350 With Factory Tow Package
    You will need a 7-way connector for your 2021 Lexus RX 350 if you plan to tow a trailer with brakes. It will have to be done in two steps. The first thing you will need is a 4-way connector. My recommendation is the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, part # 118255. This connector offers a custom fit for your vehicle. You will not have to cut or splice wires to install this connector. It has a power module that that connects directly to your battery, this keeps...

To install this just simply connect it to your existing 4-Way and then ground the white wire. This gives you the basic lighting functions for your trailer.

  • Recommendation for Adding 7-Way and 4-Way Trailer Connector to a 2013 Jeep Rubicon without Tow Pkg
    Without the factory tow package, there is not a 7-way connection that plugs right in with all the 7-way functions. You will need to install a 4-way flat connector like # 118416 first. This harness installs to the factory wiring located behind the driver's side tail light. I've attached a video to assist. Then if you don't want all the 7-way functions, but need the 7 way adapter, you can simply use the Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter w/ 4-Way Vehicle...

This terminates into a 4-way flat connector.

  • Recommended 7-Way and 4-Pole Trailer Wiring Harness for 2018 Honda Pilot
    The easiest way to have both a 4-pole and a 7-way trailer connector for your 2018 Honda Pilot would be to begin by installing a 7-way trailer connector, part # 118286 and then use an adapter like # PK12716 when you want to tow a trailer with a 4-pole connector. I've linked to videos for both these products. There's an alternative if you'd rather not mess with an adapter. You can use a T-harness like part # 118384 which would plug inline between the 7-way and the harness provided by the...

For the wiring, at present, there isn't a "plug-and-play" 7-way harness available for the 2021 Dodge Durango.

  • Recommendations For Mounting A 4 And 7 Pin Adapter To 2021 Ford Bronco Factory Hitch
    Factory mounts will end up being different than aftermarket ones, so the only thing I can recommend is removing the 4 Flat mount and drilling two holes in the hitch for the Hopkins Endurance Multi-Tow # HM47180 to mount to. On the factory hitch where your 4 Flat mount is located, it is designed for holding wiring like this, but how the 7 Way will mount will end up being very low as it will hang down below the receiver opening. What may be a better option is the Hopkins 7-Pole and 4-Pole...
