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:

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:

Easy to install and adds 7 pin connecti on.



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:

This plug is really made well and works with ease.



by:

This made fast work for pulling my camp er.



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:

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:

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:

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:

Perfect attachment method



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.



by:

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:

Sent in a timely manner and product is perfect.



by:

Working great



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:

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



by:

The set up was easy and it works well no issues

  • Parts Needed to Add Brake Controller to 2015 Infiniti QX70
    It sounds like you're pretty well set up! I'd recommend the Curt Echo wireless brake controller, part # C51180. The Echo communicates wirelessly with your smart phone, allowing you to control and monitor the performance of your trailer brakes from the vehicle cab whiteout needing extensive wiring and drilling any holes in your dashboard. All you'll need to do is install the # HM11140805 and plug the # HM47180 into it. Ground the white tire to the vehicle. The red wire would be extended...

  • Tail Light Converter For Motorhome To Connect a Trailer With Combined Tail Light Function
    It sounds like you are needing the Upgraded Circuit Protected Tail Light Converter # 119178KIT for your motorhome. This will allow you to connect to the separate turn signal and brake lights on your motorhome and will combine the turn signal/brake lights for the trailer. This terminates into a 4-way flat connector. If your trailer uses a 7-way the Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter # HM47180 will allow you to plug in the 4-way and give you connections for...

  • 2006 Mercedes R Series 4-Way to 7-Way Trailer Connection Recommendation
    The Tekonsha ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT is my recommendation for your 2006 Mercedes R-Series. This will give you a working 4-way flat. To get a 7-way connector, you would then just need to add the Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter w/ 4-Way Vehicle End Plug # HM47180 and make sure the white wire with terminal is grounded to bare metal so your lights can work properly.

  • 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 Trailer Hitch for 2008 Volvo XC90
    For your 2008 Volvo XC90, the trailer hitch you want is actually the Curt Trailer Hitch Receiver # 13559. This is the only Draw-Tite hitch confirmed to fit. For your wiring harness, you will want the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118411. This custom-fit T-One connector plugs into your Volvo XC90's wiring harness, which is located behind the driver's-side and passenger's-side interior trim panels in your rear cargo area. Once you've plugged in the T-connector,...

    If you are just needing to make the 4-Way on your 2004 Jeep Liberty compatible with the 7-Way on your trailer (without brakes) then the Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter # HM47180 is exactly what you need. 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.

  • Is the Harness Included with the Hopkins Trailer Connecotr HM47180 Available Separately
    It sounds like you are looking for the wiring harness portion of the Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter part # HM47180. If that is the case then this part is not available separately but you can obtain something similar with the Pollak Wiring Harness Extension part # PK11-934 and the Quick Fix 4 Pole Flat Trailer End part # HMC20031. If you need butt connectors to finish up your connections you can use part # DW05745-5.

  • 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...

  • Recommended Hopkins Endurance 4-Way and 7-Way Connector
    We have something almost identical to the 47188. It is the Hopkins Endurance item # HM47180. This adapter also has a 4-way and 7-way wiring harness and the built in bracket. It connects to vehicles with a 4-way connector the same way too. I have linked a review video below.

  • 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.

  • Can a Curt Echo Be Powered Off The Trailer Battery On a Travel Trailer?
    The problem with running a power wire from your travel trailer battery is there is nothing maintaining the power supply to your trailer battery and when it dies or the power begins to drop your braking can stop working. You really need to have Wire # 10-1-1 with a Circuit Breaker # PK54230PL running to the battery on your 2018 Honda Odyssey. The you will be able to safely use the Curt Echo # C51180 with the 4-Way to 7-Way Adapter # HM47180 you found from Hopkins.

It measures just 2.9"w x 3.9"d x 6.9"h and weighs less than a 1 lbs. I have linked a diagram below to show you the dimensions.

  • Troubleshooting 5th Wheel Gooseneck Wiring Installation on 2004 Ford F-350 with Factory 4-Way
    For your 2004 Ford F-350 you will utilize your factory 4-way and then wire in an adapter and the wiring for a brake controller. For your application, I recommend the Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter w/ 4-Way Vehicle End Plug # HM47180. You will plug your 4 way into this, then use a screw to ground the white wire with ring terminal. Then you will use the # 12-2-1 wire to run your 12V power wire to the red wire, the brake controller output wire to the...

  • 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.

  • 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...

  • 7-Way Adapter Recommendation for 2016 Honda Odyssey EXL with Aftermarket 4-Way
    For your 2016 Honda Odyssey that has an aftermarket 4-way you'll need to use a 7-way adapter like the # 37185 to convert to a 7-way since your vehicle does not have 7-way or brake controller factory wiring. 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...

  • 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...

There is a simple way to use the wiring you suggested to connect to your 4-way flat adapter and give you the options you desire. I recommend the Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter w/ 4-Way Vehicle End Plug # HM47180. This will connect to your existing 4-way and then you will need to run wires for the 12V power (charge)...
