Video Transcript for Hopkins Wiring - Wiring Adapters - HM47365 Review

Today we're going to review Part Number HM47365. This is the Hopkins seven-way RV to four-way flat trailer connector adapter. The nice thing with this piece is it will let you adapt a seven-way RV style connector that's on your tow vehicle to work with a trailer that has a four-way flat connector. You can see what's nice. The wire lead right here is very flexible, which allows for more installation options. Also the four-way itself has a built-in dust cover so you can see when you're not plugged in and using it just put your dust cover on it. What's nice about that is it will protect those terminals from any damage or from the elements getting to it. On the seven-way adapter what's nice is it has the built-in finger pulls which allow you to easily insert or easily remove from your seven-way.

If ever needed, there's a little screw at the top here. If you loosen that screw, this whole inside would come out and you'd have access to the wire connection points if you need to ever do that. That should do it for the review on Part Number HM47365, the Hopkins seven-way RV to four-way flat trailer connector adapter. .

I ordered the wrong plug for my hitch, and this filled the bill, to convert from the 7-pin to the 4-pin for my boat trailer. This was a lot easier than returning the original plug, and e-trailer got the new adapter to me very quickly. 579589

I am very pleased with my adapter. Enables me to connect to all of my trailers without having to add a plug to my truck or have to modify my factory wiring. Just plug it in to my 7 pin connector and go. E-Trailer folks are great people to deal with. 652100

I started from scratch not knowing the correct part, for a wire harness, for a boat trailer connection to a Toyota 4 Runner. I searched many places looking for assistance without any luck. I then found etrailer. I contacted etrailer. Nicole-Nikki responded immediately. Nicole-Nikki was excellent in helping out with the correct part. I purchased a quality harness at a great price. Everything works. Thanks again Nicole and George for shipping out and the super service. 715593

Ask the Experts about this Hopkins Wiring

  • Adding a 7-Way Trailer Connector to a Toyota 4Runner with a 4-Way
    Yes. If the 7-Way is a blade style 7-Way, which is what is sounds like, you can mount # 37185 to your 4Runner. The 4-Way will plug into it (and still be functional) and then all you will have to do is ground the white wire to the vehicle frame. The other wires on 37185 do not have to be connected but this means that only the light functions will work on the trailer. If you need all the functions to work on the trailer then instead of # 37185 you will need # ETBC7 and a brake controller,...

  • 7-Way to 4-Pole Wiring Adapter to Allow Use of Pilot Oval LED Brake Light Hitch Cover CR-017
    It sounds like your 2014 Toyota Tacoma has a 7-way RV-style blade trailer connector, like the part shown in the linked photo. To connect this type of trailer wiring to the 4-pole flat type used on the Pilot Oval LED Brake Light Trailer Hitch Receiver Cover # CR-017 you will need an adapter such as # HM47065, # HM47365 or # MT70086. These and all such adapters are shown on the linked page.

  • Need Trailer Adapter To Connect 4-Way Trailer Connector To 7-Way on 2011 Honda Pilot
    If your 2011 Honda Pilot has a 7-way trailer connector, the item you selected, Hopkins 7-Way RV to 4-Way, part # HM47365, will work for you. The # HM47365 connector will allow you to connect the 4-way connector on your trailer to the 7-way connector on your Honda Pilot.

  • What is the Difference Between Hopkins # HM47365 and Pollak # PK12716 Wiring Adapters
    Both the Hopkins # HM47365 and Pollak # PK12716 wiring adapters allow a tow vehicle with a 7-way blade-style trailer socket to connect to a trailer that is equipped with a 4-pole flat connector. Both plug in to the socket on the vehicle and provide a receptacle for a 4-pole flat trailer connector. The difference between them is that the Pollak adapter is a single piece while the Hopkins adapter uses two separate sections linked by a short length of wiring. In some applications these...

  • Are RV 7-Way to 4-Pole Wiring Adaptors Vehicle-Specific
    Trailer wiring adapters like Hopkins # HM47065, Pollak # PK12716 and Hopkins # HM47365 are not vehicle-specific products. They will work on any vehicle that has the appropriate connector. The coiled wire adapter # HM47065 that you referenced combines a trailer-side (male) 7-way RV-style plug (that mates with the 7-way socket on your Ram 3500) with a vehicle-side 4-pole flat type plug. This wiring adapter carries only lighting signals (stop, turn and tail) but not other functions like...

  • Does a Brake Controller Have to Install When Installing a 7-Way on a Trailer
    Yes, you can install a 7-way without also installing a brake controller. Basically you have all of the trailer light functions covered and then later when you add a brake controller the trailer brakes would then be functional. Then for an adapter to convert the 7-way to a 4-way you'd only need the part # HM47365 and you'd be set.

  • Adapter Needed to Convert 7-Way on 2016 Honda Pilot to 4-Pole
    The Hopkins # HM47365 7-Way to 4-Pole Adapter you referenced is exactly what you need. Simply plug the adapter into the 7-way on your Pilot, and plug the trailer's 4 pole connector into the plug on the other end of the adapter. If you click the provided link, you can see a product description video featuring the adapter.

  • How to Tow a Trailer with a 4-Way Flat Connector with a 2010 Buick Enclave with 7-Way Connector
    To convert the 7-way trailer connector on your 2010 Buick Enclave to a 4-way flat connector, you can use the Hopkins 7-Way RV to 4-Way Flat Trailer Connector Adapter, # HM47365. This adapter will allow you to power the lights on your trailer without having to install a new wiring harness on your vehicle. This way you can tow a trailer with a 7-way in the future if needed.

  • What Adapter is Needed For Borrowed Trailer Pulled By Mercedes-Benz ML350
    It sounds like you have a 7-way connector on your ML350. If the trailer you plan on towing has the female version of your connector then you will not need an adapter. The other possible situation is you have the 7-way male connector on your ML350 and the trailer has a 4-way. If this is the case then Hopkins # HM47365 should work. In order to determine exactly what will work with the trailer, we will need to know what connector is used on the trailer. Not all trailer companies use the...

  • 7-Way to 4-Way Adapter Recommendation for a 2011 Mercedes ML350
    Yes, the adapter part # HM47365 would work well for you based on your description of what you have. It sounds like you have a 7-way connector at the back of your 2011 Mercedes ML350 and a 4-way connector on your trailer. This adapter would convert the 7-way to a 4-way and would work well for you. The 4-way connector is still a very widely used connector for trailer wiring. It most often used on trailers without brakes, whereas the 7-way is used on trailers with brakes. If your trailer...

  • Taillights and Turn Signals Working But No Brake Lights on Trailer
    Almost every trailer in the U.S. uses a 2-wire or combined wire tail light setup. This means that the turn signals and brake lights are on the same circuit and use the same bulb in the trailer tail light assembly. Because of this, virtually every trailer wiring adapter is designed to carry the turn signal and brake lights on the same pin circuit, so I would assume that this is the case for your 7 to 4 way adapter. It sounds like with working turn signals and taillights, that the problem...

  • Towing Trailer with 4-Pole Connector with 2001 Land Rover Discovery with 7-Way
    If your Discover has the 7-way connector that uses the round pins like part # PK11720, we do not offer a pre-made adapter, but one can be easily constructed using a 4-pole vehicle end connector like part # 18002 and a 7-way round pin trailer end connector, part # PK11700. The 4-pole would be wired to the 7-way round pin as shown in the diagram I made for you. If your Discovery has the 7-way with the blade-style pins like part # PK11893, an adapter is available, part # HM47365.

  • 7- to 4-Way Adapter for a 2015 Chevy Tahoe with Factory 7-Way Trailer Connector
    Yes, the 7-Way socket on the 2015 Chevy Tahoe is the same in function as those on any other vehicle with a 7-Way blade style connector so your friend can use adapter # HM47365. I have included a link to a video review of this adapter for you.

  • Boat Trailer Lights Do Not Work with 7-Way to 4-Way Adapter with a 2005 Toyota Tundra
    There could be a problem with the adapter or it could be pinned out differently than your truck. First, use a circuit tester like # 40376 if needed to test the 7-Way on the truck. If all the functions on the pins are working properly, you can eliminate the truck as the problem. If they are not working properly then that would indicate a problem on the truck side and you will want to check all the relays/fuses related to the tow package wiring. If the truck checks out ok, plug in the...

  • RV Brakes Lights Work Until Tail/Running Lights are Turned on
    There are a few different reasons why turning your running lights on keeps your brake lights from working. The first is a bad ground. Check all of the ground connections for your lights and make sure that they are securely connected to a clean, bare-metal surface. If those look good then you likely have too many lights on your unit. Try disconnecting some lights, one at a time, and see if your brake lights eventually start working while your running light circuit is powered. If you...

  • 7-Way to 4-Way Trailer Connector Adapter for a 2007 GMC Yukon
    If your 2007 GMC Yukon has a 7-Way blade style trailer connector and the trailer has a 4-Way flat trailer connector then yes, you can use adapter # HM47365. If you have a different type of connector on either vehicle let me know and I can determine the correct adapter for you.

  • Will the Hopkins Adapter # HM47365 Fit a 2005 Chevy Trailblazer
    The Hopkins 7-Way RV to 4-Way Flat Trailer Connector Adapter # HM47365 is actually a universal fit so it is compatible with your 2005 Chevrolet Trailblazer. You simply plug the 7-Way end into the 7-Way on your Trailblazer and then connect the 4-Way on your trailer to the other end of the adapter. I have attached a review video for you to check out as well.

  • Will the 7-Way to 4-Way Adapter HM47365 Fit a 2014 Toyota Tacoma

  • 4-Way to 7-Way Blade Adapter Recommendation
    The part # 118710 will technically fit your 4-way but most likely the 7-way you need is different than what this provides as this is a Euro 7-way that wouldn't be found on an American spec vehicle. For a similar setup that would give you most likely the 7-way you need we have the part # HM47365 which has a 7-way flat connector instead.

  • Trailer Wiring Adapter to Join Truck 7-Way with Trailer 4-Pole Connector
    It sounds like your Durango has what we call a 7-way blade type trailer socket, which is shown in the linked photo. This common trailer connector uses flat or blade type contacts. We offer adapters to join this type of connector to the 4-pole you have on your trailer and you can see all on the linked page. For example, Pollak # PK12716 plugs in to your Durango's 7-way and provides a connection point for the trailer's 4-pole wiring harness. Others like the coiled-cable adapter # HM47065...

  • B&W Tow & Stow 3-Ball Mount that Fits 2018 Chevy Silverado 1500
    The B&W Tow & Stow 3-Ball Mount # BWTS10048B that you referenced will fit perfectly to the 2 inch hitch you have on your 2018 Chevy Silverado 1500. For a hitch lock the part # 63232 is a great option as it also doubles as an anti-rattle device which means there will be less movement. To lock the ball mount platform to the shank you'd then want the part # AM3492. Then for a 7-way to 4-way adapter the part # HM47365 will work really well and is also easy to use.

  • Enclosed Carrier Recommendation for a 2013 GMC Acadia
    For a hitch mounted, enclosed carrier for your 2013 GMC Acadia your best option would be the Rola Swinging Enclosed Carrier part # 59109 that you referenced. This carrier will give you complete cargo area access unlike the other styles of hitch mounted carriers. This carrier uses a 4-way harness to activate the taillights of it. Since you have a 7-way you will need a 7-way to 4-way adapter like the part # HM47365. I attached a review video for this carrier for you to check out also.
