Worked out pretty good. Had a hard time figuring out just how to attach it. I ended up just zip tieing it. It was a life saver that I could pull the rear plug apart. Made it possible to slide part of the harness thought a tight hole.



by:

This plug is really made well and works with ease.

Hopkins makes a pretty nice trailer wiring kit. Coming also with a four pole outlet makes for a really nice unit. The housing also seems to be make fo decent material and does hold up well in wet climates where I live. Cant go wrong using this connector kit.



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

Plug continues to perform satisfactorily. Happy with Etrailer service.



by:

This was exactly what I needed to convert the factory 4 pin to a combination 4 pin and 7 blade connector. It's been working great with both my trailers.



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:

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)

This receptacle was easy to install and has worked great. No problems at all.



by:

Living in NY, the winter salt killed my previous 7 way within two years. Purchased this item in hopes that it will hold up better. Time will tell.
Ordering, receiving and install went smooth. Seems a little better than my old one.



by:

One year later still works good



by:

Easy to install and adds 7 pin connecti on.



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:

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:

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:

Perfect fit with factory wiring harness connector.



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:

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:

This made fast work for pulling my camp er.



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:

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



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:

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

Great product and great price

I originally felt that this adapter was overpriced but after realizing how simple this made the install it was money well spent



by:

Perfect attachment method



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:

Sent in a timely manner and product is perfect.

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

  • Is Hopkins or Pollak Better for Trailer Connectors?
    Personally, I'm a much bigger fan of Pollak than I am of Hopkins. In my experience, I've had fewer issues with 7-way plug fitting loosely with Pollak brand 7-ways and Pollak is generally the "go-to" brand for most OEM truck setups.  The snag is there isn't a 4-way and 7-way Pollak branded trailer connector currently, but I have some good news. The Hopkins 7 and 4-Pole Trailer Connector, # HM40975, is actually made by Pollak, but sold by Hopkins. This is the same plug I have on my Silverado...

  • Best Way to Install 4-Way/7-Way Wiring Harness on a 2019 Ford Ranger
    Sounds like you've done a great job at installing the Redarc Tow-Pro Elite # RED44FR, and that you're on the right track when it comes to installing the Hopkins Endurance Multi-Tow Plug # HM47180 on your 2019 Ford Ranger! To wrap up your installation I actually recommend picking up the Curt T-Connector Vehicle Wiring Harness # C56431 and then removing the 7-Way plug and replacing it with the Hopkins 4-Way/7-Way since they both have the US CAR connector at the back. Simply unplug the Hopkins...

  • Recommended 7-Way to 4-Way Adapter Just for Trailer Lights
    If you don't care about brakes all you need is the Mighty Cord Trailer Connector Adapter item # A10-7084VP. You would plug your Honda's 4-way into the adaptor's 4-way and then plug it into the 7-way of your trailer. The lights will function but nothing else will. You will want to tape up the extra wires or cut them off if you have no intention of ever using them. This is the simplest and least expensive way to do what you are wanting.

  • 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.

In the video we also use the # ETBC7 kit for the wiring. You could have gotten our # ETBC7 kit which includes the 7-way adapter and all the wiring, connectors, and breakers you need but since you already have the Hopkins # HM47180 you can add our # 5506 kit for the rest of the parts.

  • 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.

    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...

  • 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...

    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...

    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...

That said, I would recommend the part # ETBC7L for the 7-way adapter and then for a brake controller the Curt Echo Mobile # C51180 as this is the easiest to install and best option. Once you plug it into your 7-way and it's synced to your smart phone it's totally ready to tow without...
