Video Transcript for Hopkins Wiring - Wiring Adapters - HM47200 Review

Today, we're going to review part number HM47200. This is the Hopkins Endurance Quick-Install 4-Way Flat to 7-way Blade Adapter. Now, this kit will convert your vehicle's 4-way flat trailer connector that's on your tow vehicle to a 7-way RV style connector that will be on your trailer. It's a very simple installation. Basically what you would start with is take this 4-way right here, plug it into your adjusting 4-way that's on your vehicle and then plug this into your 7-way and then take your white wire with the eyelid on it and make a ground with it. Then, your three remaining wires will need to be hard wired in. Basically, the blue wire right here is for the electric brake function, the red would be for an auxiliary 12-volt power, and then the purple would be for your backup reverse light function. With that all connected, then you have a 7-way that you'll be able to plug in the 7-way from your trailer. Now, you can also, if you do not need to use it as a 7-way. If you just want the lights to function on your trailer with ...

You have a 7-way on the trailer and you want just the lights to function, you don't need all the other functions, you can just plug this into the 4-way on your tow vehicle. Plug this into there, make your white wire ground, and then when you plug in your 7-way, it will just give you the light functions, so you can use it either way. Now, on this adapter right here, the 7-way, the lid on it opens 180 degrees or more. Gives you nice, easy connection. It is is spring loaded, keeps out any dirt, moisture. It has a nice seal on the cap and the terminals are corrosion resistant, so gives you nice weather proofing. The whole unit is made of a durable ABS plastic construction, has a nice oversize hinge, so it holds up under many openings and closings of the hinges or the lids or the cap itself. Now, it also comes with the mounting screws and some dielectric grease.

Mounting screws are used to attach this to the vehicle, and the dielectric grease; any time you make electrical connections, you should put some dielectric grease on it to help prevent corrosion. That should do it for the review on part number HM47200, the Hopkins Endurance Quick-Install 4-Way Flat to the 7-way Blade Adapter. .

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!!!! 219370

Excellent products that resolved my trailer connection issues.

I purchased the endurance model expecting a much improved version of the standard product, however the product was not sealed as well as the lesser equivalent product, and cannot be sealed from the elements, and came in two parts, to be unsealed to the elements and snapped together by the installer. I would have much preferred a sealed assembly, like the lesser equivalent model. 129227

Do you have a question about this Wiring?


  • Recommended Wiring for 4-Way to 7-Way Trailer Connection
  • The Hopkins Endurance Quick-Install Trailer Connector Adapter - 4-Way Flat to 7-Blade # HM47200 is a great start for your 7-way molded trailer connector, but you will need to not only install the 4-way trailer connector, but also make sure you have a good ground connection on the white wire with the terminal ring. This will not give you a good connection without a bare metal to metal connection on that wire. Then you can add the other 3 wires to complete your 7-way. The purple wire...

  • Recommended 7-Way Wiring and Brake Controller Installation on 1996 Dodge Ram 2500 with 4-Way Wiring
  • For your 1996 Dodge Ram 2500, I recommend the Tekonsha Prodigy P3 # 90195 for your brake controller which will connect to the factory harness you mentioned using wiring harness # 3020-P. This brake controller is easy to use with its presets and LCD screen. For the 7-way, you will then use # ETBC7 and splice into the factory wiring located under the driver's side wheel well. This will give your the wiring functions needed to complete your 7-way and give you the brake controller functionality...

  • 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.

Once installed it will provide you with both a 4-Way and a 7-Way connector. It comes with the wiring and circuit breakers you will need along with a mounting bracket. I have included a couple of links that explain and show the ETBC7 installation for you. If you will be towing any trailers that have...

  • Adding In-Bed 5th Wheel/Gooseneck Trailer Wiring on a 2013 Dodge Ram 3500
  • 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...

  • 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...

  • Adding a 7-Way Trailer Connector to a 2015 Chevy Tahoe
  • For a 2015 Chevy Tahoe that did not come with a factory installed 7-Way you can add one using # 30955. Installing this part will actually give you both a 4-Way flat and a 7-Way. I have included a link to a video showing an example installation.

  • 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...

  • 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...

  • Troubleshooting no Running Lights with the Hopkins 7-way to 4-way Adapter part # HM47200
  • The Hopkins Endurance Quick-Install Trailer Connector Adapter # HM47200 that you referenced should work well without any modifications. It sounds like the running light issue you are seeing is on the 4-way of his F150. Use a circuit tester like our part # 3808 to test the pin with the brown wire coming out of it for voltage when the head lights or running lights of his vehicle are on. If there is no voltage there then the problem is on the vehicle side of the wiring. Trace the circuit...

  • 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...

  • 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.

  • 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.

  • 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...

This includes a combination 4-pole/7-way vehicle socket and all the connectors and wiring needed to install it. Your existing 4-pole will plug right in to the mating connector on the 7-way and you'll then make the other circuit connections for 12V power, reverse light signal and trailer brakes.
