This adapter plugs into your 7-way, blade-style, vehicle-end connector to convert it for use with a 7-way, round-pin-style, trailer-end connector.


Works as should from truck to farm equi pment.


Works great and good quality also.


The right tool for the job!


We bought a couple of these to throw in our pickup’s they have proven to be very useful, and we have had no problem with them.


Easy to find part and get it delivered.


This adapter is all I need to make testing of trailer light and brakes installed with 7pin round connector a quick and easy job. Product is well build..
Price was good and shipping was great..



Works Great! I use all the time when I need to test trailer lights and brakes.


This HOPKINS product 47595 is exactly what I was looking for and thank goodness it is carried by ETRAILER.COM. Reasonabley priced on this quality product, i couldn't be more pleased. Attached to my seven pin flat to round pin trailer plug and all works. ETRAILER.COM kept me informed with emails and a courtesy phone call on shipping. GREAT company, will be doing business in future with ETRAILER.COM.


I have a couple of different trucks and trailers with different plug configurations. Seven way round and seven way flat ( RV ) this adapter was wired correctly, was just what we needed.


Works great to hookup to my farm equipm ent.


This works perfectly and is small enough to fit in your glovebox or job box so you always have it when needed. I use it for one trailer so I do not have it mounted but more as a work around since that trailer is only used several times a year. Save yourself the headache of wiring and purchase this.


I purchased this adapter because I didn't have time to assemble one myself but it didn't work. It was not wired correctly! When I tried backing up with the electrical plug connected, it applied the brakes and wouldn't allow me to move the trailer without disconnecting the plug. Once I got the wires in the right place it worked fine. The wires are all a heavy guage and it has the rubber boot to cover the screws on the back side of the vehicle plug. Very pleased once we got the wires in the right place.


Basically they built what you could build yourself. You could buy the parts and take the time to build it but you would not save money or time or be able to build it any better. They only con would be the 7-way pin plug is bulky since it was intended for a vehicle application and to be bolted in. They used the best parts I have seen available and have a good build quality. Buy it if you need it, it's worth it!


Adapter just arrived this afternoon. Have not hooked up the trailer yet but it looks like it will probably fit. Will try it out this weekend and let you know if there are any issues. Thanks for getting it to us in a hurry, thanks for the great customer service.

Michael L.


Just fine, no problems.


The product worked, but the metal end cannot be attached to the bumoper of the truck becuase the wiring between the connectors is not near long enough.

I would like to see a similar connector made with both ends made of rubber so that it does not need attached to the bumper and then it will not mar the bumper when attached to a trailer.

by: is awesome, package was stolen out of my mailbox, and once I filed a police report, they shipped me out a replacement at no cost and the item received was of great quality


The online diagrams made the correct adapter choice easy. The wiring adapter worked perfectly right out of the box. I later needed a second adapter for a different application and it was perfect as well.


Although the order was held up for some reason and then snow caused a delivery hold up, I finally got the part and it is exactly what I needed. I haven't had the need to use it yet, but the problem I purchased it for is resolved. So unless there is some sort of manufacturer fault, I can't see any reason this adapter wouldn't serve the purpose I bought it for. I would certainly suggest & buy other trailer needs from again.


It worked out perfectly, I have to transport a borrowed telephone pole trailer from out line workers training back to PPL and to able to use the trailer light is a biggie


Hard to find this anywhere else, I'm glad etrailer had it. We use it to hook our hay baler and shredder lights up to the truck instead of the tractor. We've already ordered more after the first one so we can have one for each truck.


great customer service kept me informed about the delay with the product just hated the amount of time it took to get the items in Stock and shipped out to me but i understand that is beyond your control


Just as described. Works great. Saves a lot of hassle rewiring the trailer plug if you are borrowing it from someone else.


Works great... I pull a lot of farm machinery with my pickup truck and all farm plugs are 7 way round. With this adapter it just made things easier...


Great product just what I needed could not find any where elsebut e-trailer had it very knowledgable and helpfull delivery


Exactly what I needed to be able to connect to my heavy equipment trailer. etrailer is always my go to company for anything trailer related. Never had a problem and always receive my products quickly.


Works really well to adapt a commercial type plug over to an RV connector without having to change over and rewire.

  • Availability of 7-Way Round to 7-Way Blade Adapter
    Hey Paul, so the ISO 3731 7-way is a 7-way round which we have adapters to go from this to a standard RV style 7-way with the part # ADP7R-7B or if you need the opposite orientation part # 47595.

  • How to Plug Lance Camper With Lance Plug Into 7-Way Blade on Truck
    I do have a solution, but since Lance has their own plug design there are no adapters that will work, including the # 47595. The best option is to replace the lance plug with a standard 7-way blade connector like the # PK12706. This will eliminate the need for an adapter since you can plug it in directly after replacing the connector.

  • Can Tekonsha Trailer Wiring Circuit Tester, # 8010 be Used to Test a Semi Tractor Trailer
    Semi tractor trailers usually use a 7-Way round pin connector rather than the 7-Way blade style connector that the Tekonsha Trailer Wiring Circuit Tester, # 8010, is designed for. However, it is possible to use an adapter, like the Adapter 7 Way (Blade) to 7 Way (Round Pin), # 47595, to be able to test the semi wiring.

  • How To Plug 1997 Lance Truck Camper Into 7-way Connector On 2016 Ford F-250
    We have run into this quite a few times in the past, and the best option will be replacing the Lance 7-pin connector with a standard 7-way blade connector like the # PK12706. This will give you a standard 7-way connector to plug into the factory 7-way on your 2016 Ford F-250. There is not a adapter compatible with the connector on your 1997 Lance Camper as they use their own style connector that does not match any standard connectors. I included a video of the # PK12706 for you to take...

  • 7-Way Trailer Plug Adapter or Compatibility with Lance Slide-In Truck Bed Camper
    Lance does have a proprietary plug, but many customers see a standard 6-way or 7-way round and notice it doesn't fit their factory 7-way as well. I've attached an article to help if you have one of the 7-way or 6-way round connectors which we do have adapters for. If you have a 7-way round, then you will use adapter # 47595. If you have a 6-way plug then you will use adapter # 47549 or # PK12728. If you have the special Lance plug, I recommend replacing it with # A7WCB which would directly...

    When you disassemble each style of connector, you will find that each terminal is labeled by number. The 7-way round pin is wired as follows. Number 1 is the ground, 2 is the reverse lights, 3 is the left turn/brake lights, 4 is 12 volt auxiliary power, 5 is the right turn/brake light, 6 is the tail/marker light and 7 is the brake output. The 7-way connector with the blade pins is wired differently. Terminal 1 is ground, 2 is brake output, 3 is taillights, 4 is 12 volt accessory power,...

    We do have the parts you're seeking for your 2021 Ford F-350. If you wanted a stake pocket tie down, the Brophy Stake Pocket Mounted Camper Tie Downs - Bed Mount - Black Powder Coated Steel - Qty 4 # TDSF are a universal solution that would work well; the only draw back to these is that they are permanently installed and do require drilling to install.

  • How to Install Trailer Wiring 7-Way on Older Truck with Separate Turn Signals from Brake Lights
    You'll first need to install a 4-way on your truck that is designed to take separate turn signals and convert them to combined. For that you'd want the part # 119250KIT which will give you a 4-way that has combined circuits. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything...

Then from there you'd need to convert it to a 7-way you'd need the part # 37185 which is the style that uses blades for the pins.

  • 7-Way Recommendation for a 2008 Honda Ridgeline
    If you have a factory 7-way at the rear of your 2008 Honda Ridgeline but there is no voltage at any of the pins most likely you would need to check the fuse/relay panel to install/replace the towing related fuses/relays so that the 7-way would function. The only way we offer to install a 7-way on your vehicle would be to first install a 4-way like # 118400.

  • Brake Controller Wiring for 2008 Honda Ridgeline With 4-Way
    If your 2008 Honda Ridgeline is not wired for a brake controller you are going to need the Universal Installation Kit for Trailer Brake Controller # ETBC7 which includes the wiring, circuit breakers and the necessary 7- and 4-way connector. You will need to plug this into your Ridgeline's 4-way and then wire the 7-way. For your trailers that only have a 4-way you can simply use the Pollak 7 Pole to 4 Way Connector Adapter # PK12716 to connect your trailer to the 7-way on your '08 Ridgeline.

  • Adapter for Trailer with 7-Way Round Connector and 2012 Honda Ridgeline with 7-Way Blade Connector
    It sounds like the connector on the boat is an adapted 4-Way to use with a 7-Way round pin trailer connector on a vehicle. That would be why there are just 4 pins, 3 for the lighting functions and 1 for ground. If that is the case then the 7-Way blade to 7-Way round adapter, # 47595 should work just fine. Most boat trailers have the basic lighting functions but do not have the components that require the other circuits such as 12 volt accessory power and electric brakes.

  • 7-Way Blade to 7-Pin Adapter for Towing a Trailer with A 7-Pin Connector
    The wiring for the 7-Pin connector is different than the 7-Way blade connector. You will need an adapter to make the two different styles compatible. You can use the Adapter 7 Way (Blade) to 7 Way (Round Pin), # 47595. The blade end plugs into the 7-Way on your vehicle and the trailer round pin 7-Way will plug into the receptacle. I have also included a link to a wiring FAQ article that shows how the two styles differ from one another.

This will work and is a perfectly fine solution. The only thing I might suggest otherwise is using an adapter like the # 47595 instead.

  • Adding a 7-Way Round Pin Trailer Connector to a 2010 Ford Expedition with a Factory 4-Way Flat
    Vehicles manufactured now-a-days are fitted with the blade style 7-Way so that is what most manufacturers make to fit vehicles either as replacements or aftermarket add-ons. To add a 7-Way round pin to your 2010 Ford Expedition you will need # PK11720, boot # PK11761, and mounting bracket # PK11771.

  • Brake Controller and Install Harness Recommendation for a 2012 Ford F-150 with 7-Way
    The 7-way on your 2012 Ford F-150 carries the brake output circuit that will activate the brakes of a trailer. But you will first need to install a brake controller in your truck as that does not happen automatically. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle...
