It took awhile to receive my order, but I was informed by e-mail and was kept informed when I should expect delivery. Luckily, was in no rush, so I would reply and wait for an update from you.
i received the connector in good condition. Thank you!

Easy install thanks

Installation went well and works fine. Only issue was the screws included with the product were not the right ones so had to replace which wasn't a big deal.



by:

Excellent products that resolved my trailer connection issues. The "Hopkins Quick-Install Trailer Connector Adapter 4-way flat to 7 blade HM47200" and the "T-1 Vehicle Wiring Harness with 4 Pole Flat Trailer Connector 118334" were the perfect combination for the quick, simple and successful installation on my 2001 Dodge Durango. Along with the great products "etrailer" provided helpful information on their website, and fast shipping! Thanks again!



by:

Used the wiring harness and an adapter plug to give my Cherokee a factory installed towing kit look. No connector wires visible. Great product.



by:

The adapter works great! I used it the day that I got it. I have an 18' car trailer that I just needed to take down to get a VIN inspection and I wanted to use my Jeep Wrangler because it's so easy to maneuver the trailer. I plugged the 7 blade from the trailer into the adapter, plugged the 4 wire flat into the Jeep, connected the ground wire, and the lights and turn signals all worked fine!!!!



by:

Used this to install a 7 pin plug on my vehicle instead of having to use an adapter on the 4 pin plug. Hooked it up to the travel trailer and lights worked great.



by:

Simple install. I was going from a 4-flat plug to a 7 blade without trailer brakes, so it was nice and simple. I was going to cut the extra wires off, but decided against it. I just zip-tied them up out of the way JIC I need them later.



by:

The 4 Pin Flat to 7 Pin Trailer Connection was very hard to find. Thanks for the Products that you make of high Quality. You won’t go wrong with ETrailer Products.

I wish I could have just got a plug that was 4 way flat to 7 blade, but this was all I could find. It will work for what we need it for.



by:

Fast shipping



by:

Quick delivery, excellent installation videos.



by:

Worked out great. I didn't have to rewire because of this adaptor. Plugged my rv plug in and then connected to my 4pin truck.

  • Adapter for 4-Flat on Truck and 7-Way on Trailer
    We do have a solution for you, though the Reese Trailer Connector Adapter # 78118 will not work for you. Instead I recommend the Hopkins Endurance Quick-Install Trailer Connector Adapter # HM47200 which will plug into your truck's 4-way and allow you to connect your trailer's 7-way.

  • Recommended 4-Pole to 7-Way Trailer Connector Adapter
    The # HM47200 would indeed adapt your existing 4 pole to a 7-way blade-style trailer connector. In that respect, it would work just fine. However, I typically recommend going with the # 37185 instead, as the adapter also offers a 4-pole connector. If your trailer doesn't have or need trailer brakes or a need for a 12-v power supply, you'd simply plug the adapter into your existing 4-pole, and ground the white tire to the vehicle frame. This will provide you with lighting functions, and...

  • How to Ground the Hopkins Endurance 4-Way to 7-Way Adapter # HM47200
    The ground wire from the Hopkins Endurance 4-Way to 7-Way Adapter, # HM47200, should be grounded to either a clean, bare metal surface on the frame of the vehicle or to an existing ground stud on the vehicle. On the trailer side, the ground wire from the trailer connector should be connected to a clean, bare metal surface on the trailer frame. I have attached a typical trailer wiring diagram and highlighted the vehicle and trailer ground wires for you to check out.

  • Parts Needed to Install a 7-Way Trailer Connector on a 2007 Honda Odyssey
    I installed a trailer hitch and trailer wiring on my mother-in-laws 2007 Honda Odyssey and I can tell you that unfortunately there are no plug-in 7-way wiring harnesses. To install a 7-way connector on your Odyssey, I recommend first installing a 4-way harness like the Tow Ready T-One Wiring Harness, # 118438. This is a plug-in harness that does not require cutting or splicing. I have attached the installation instruction and an installation video on a 2007 Honda Odyssey for you to check...

  • Installation of Hopkins Endurance 4-Pole-to-7-Way Trailer Connector Adapter HM47200
    When the Hopkins Endurance Quick-Install 4-Pole-to-7-Way Trailer Connector Adapter # HM47200 is connected to vehicle 4-pole wiring it will pass through only those basic lighting signals unless the pigtail leads for the other circuits are connected. On this item those extra pigtail leads are as follows: blue is for connection to a trailer brake controller to deliver its output power to the 7-way to activate trailer brakes; the red wire is for the 12V auxiliary power feed and connects to...

  • Ground Wire On My Hopkins 4 Flat To 7 Not Connected.
    The Hopkins Endurance Quick-Install Trailer Connector Adapter - 4-Way Flat to 7-Blade Item # HM47200 does have a white ground wire going to the 4-way flat connection. The contrast on the photo may be hard to differentiate on your screen or mobile device. It is there though, so no there will be no problem!

  • Installation of Curt C51180 Echo Wireless Trailer Brake Controller on 2006 Honda Odyssey
    Rather than using the # HM47200, I'd go with the # ETBC7L, which includes a 4-pole to 7-way adapter plus the wire and circuit breaker needed to run the power supply wire up to the positive battery terminal that's needed to power the Curt # C51180 wireless brake controller. You'll only need to run one wire from the adapter to the battery at the front of the vehicle, and ground the adapter's white wire to the vehicle. The remaining wires on the adapter won't be needed. I'll link to some...

  • Is T-Connector Trailer Wiring Harness Available For 2015 Ram 1500
    If you are looking for a fifth wheel/ gooseneck connector for your truck with the 64 inch bed I recommend the Pollak, part # PK11893-11932. Most installations are done behind the wheel well so the 7-1/2 ft wiring should give you plenty of room. If you plan on installing the harness forward of the wheel well then I would recommend the Hopkins Custom Fit Vehicle Wiring, part # 41157. This harness has 10 ft of wiring and the extra length may work better for you. If you have no 7-way connector...

  • 7-Way/4-Way Adapter Recommendation that Has Both Connectors Active
    The 4-way and the 7-way sides of the 7- and 4-Pole Trailer Connector Socket # HM40975 are both active at the same time but you'd most likely find that accessing both connectors at the same time would be challenging due to the lid design of the adapter. A better option that uses the same round connector is the part # 30955 which gives you both trailer wiring connectors active at the same time.

  • Recommendation For Best Set-Up On 2022 Subaru Outback Wagon To Tow Camper
    If your 2022 Subaru Outback Wagon does not already have a Hitch, I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver, # DT73RR. This is a Class III hitch with a maximum gross trailer weight of 4,500 lbs. and max tongue weight of 675 lbs. This will definitely handle your pop-up camper but please note that the hitch ratings are limited by the max tow ratings of your vehicle. Please refer to your 2022 Subaru Outback Wagon's Owners manual for vehicle specific ratings. The max tow...

  • Wiring Kit to Install Electric Brake Controller
    There is a kit available for you to wire in your electric brake controller. Since you already have a 4-way as well as the Hopkins Adapter # HM47200 you will need the Wiring Kit for Electric Trailer Brake Controllers # 5506; I've added links to video reviews of this kit for you to take a look at.

  • Recommended Trailer Hitch Receiver, Trailer Wiring, and Brake Controller for 2002 Ford F-450 Chassis
    For the weight capacity and ease of installation, I recommend the Draw-Tite Ultra Frame Trailer Hitch Receiver - Class V # 41947. This hitch is a confirmed fit for your vehicle. For your wiring harness, I recommend the 4-Pole Hardwire Kit with Circuit Tester # 18252 which will splice into your current tail lights. Then you will need # 10-2-1 sold by the foot to reach the factory run wires along the rear frame rail along with the Hopkins Endurance Quick-Install Trailer Connector Adapter...

  • Is the Hopkins 7-Way Adapter HM47200 Compatible with the Gooseneck 7-Way Adapter 41157
    Yes, if you used the # HM47200 as a way to wire in a 7-way on your truck you could then use the part # 41157 as a way to also install a second 7-way in the bed of your truck for a gooseneck hitch or a fifth wheel hitch.

  • 4-Way to 7-Way Adapter Recommendation for a Trailer That Does not Have Brakes
    Since your trailer doesn't have brakes you could use the # HM47200 as an adapter for your 2016 Toyota Highlander. You would just want to tape up the extra wires that wouldn't be used. After that you would just need to plug in the 4-way of the adapter to the 4-way of your vehicle and the 7-way would be ready to plug into the connector on your trailer.

  • Adding a 7-Way Trailer Connector and Brake Controller to a 2014 Nissan Frontier with a 4-Way
    First, there are a couple of ways you can add a 7-Way trailer connector to your 2014 Nissan Frontier. You could hardwire it or you can use a plug and play 7-Way. I recommend the plug and play type, # C56226, because it costs about the same as the hardwire kit, # ETBC7, and it will be much easier to install. If you choose the hardwire kit that means you also need to hardwire in the brake controller. But if you go with the plug and play style you would just need the brake controller and...

    I was unable to find your order number to determine the adapter you purchased from us so let's start with the correct one that you need, which is the Hopkins Endurance Quick-Install Trailer Connector Adapter - 4-Way Flat to 7-Blade # HM47200. All you need to do with this is plug this into your vehicle's 4-way and connect your trailer's 7-way to it. The added wires of this adapter are not needed so you can simply tie them off. If you do have an adapter like this already and you are still...

  • Brake Controller Installation in 2006 Dodge Ram 2500
    In order to actuate your trailer brakes, you'll need to install a brake controller to operate them, as your truck doesn't already have a brake controller. Since your Dodge Ram 2500 doesn't have the factory 7-way, not all the brake controller wiring was sent to the rear of the vehicle. I'd be happy to suggest parts to install a controller and a 7-way, plus provide links to some install footage that will help walk you through the process. For a brake controller, I'd recommend the Brake...

  • Can Hopkins Endurance Trailer Connector Adapter Just be Grounded and Other Wires Not Connected
    Yes, you can just plug in your 4-Way to the Hopkins Endurance connector, # HM47200, ground it, and not connect the remaining wires if they are not needed. You can tape them up and stow them out of the way. For future reference, the blue wire would connect to the brake output circuit from a trailer brake controller. The red wire would connect to the positive battery terminal via a 40 amp circuit breaker # PK54540. And the last wire would tap into the reverse light circuit.

  • Adding a 7-Way Trailer Wiring Harness at the Back and in the Bed of a 2003 Ford F-350
    If your 2003 Ford F-350 has a factory installed 4-Way wiring harness then to add a 7-Way you will need adapter # HM47200. You can then follow the installation instructions outlined in the FAQ article I have linked for you. To add a 7-Way in the bed after you have installed the rear 7-Way you will need to use harness # 41157. This will basically plug in line with the rear 7-Way and the long cable allows you to mount the 7-Way receptacle in the truck bed.

    Yes, the Hopkins Endurance Quick-Install Trailer Connector Adapter # HM47200 that you referenced would work great for you and would only require you to plug the 4-way of the adapter into the 4-way of your 2003 Dodge Dakota and the trailer lights would function.

    For the 2013 Dodge Ram 3500, if the truck came with a factory 7-Way trailer connector (most of them do), then there are 2 options for adding in-bed 5th wheel/gooseneck trailer wiring. First, you can use # 41157. This connector plugs in line with the factory 7-Way just behind the connector at the back of the truck. Second you can use # PK11893-11932. This harness also plugs in line with the factory connector but requires a little manual hardwiring as well. The diagram for this is on the...

  • Is Using The Ground Wire On the Hopkins 4-7 Pin Adapter Required?
    With the Hopkins Endurance Quick-Install Trailer Connector Adapter # HM47200 you will need to connect the ground wire using a screw or bolt to a good grounding point on your 2023 Subaru Outback XT. Do understand that the trailer likely does have an onboard battery that would charge off your tow vehicle even without having trailer brakes. This would require a Charge Line # RM-156-75 also be added to your Outback.

  • Replacing the 7-Way Connector on a 2006 Dodge Ram Truck
    Sounds like your 2006 Dodge Ram 3500 was wired to be used with a 5th wheel or gooseneck trailer. If you are wanting to switch the 7-way plug back to its original location, then you will need to use the 7-Pole and 4-Pole Trailer Connector Sockets w/ Mounting Bracket and Wiring, # HM40975-11998. This product will allow you wire your Dodge for both a 7-way and 4-pole flat and relocate the plug back to your bumper. Since someone has altered the factory plugs, you will have to hard wire your...

  • Can Hopkins 7-Way Adapter HM47200 be Used to Install Curt Mobile Echo Brake Controller
    Yes you could use the # HM47200 with the Curt Echo Mobile brake controller # C51180 but you would need additional components to complete the install since the 12 volt accessory circuit would need to be active on the 7-way. We have the part # ETBC7L instead which is a kit that includes a similar adapter and needed wiring/breaker but if you wanted to make the # HM47200 work you'd need 10 gauge wire like part # 10-1-1 (sold by foot) with a breaker like # PK54530 to make it work. The 10 gauge...
