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.


Works great to hookup to my farm equipm ent.


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.


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


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.


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.


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.


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.


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.


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.

Just fine, no problems.


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.

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


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.


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


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...


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


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


Just what I needed to go from my tractor accessories to my truck


Great idea! Adds flexibility to towing various trailers. The mechanics at work made their own for about the same price I paid, without spending the time for assembly.


this is a great product. Better than having to wire another plug in on the back of my trucks and i can use if for more than one truck

  • Mounting Hole Locations for Hopkins 7 Blade to 7 Round Trailer Connector Adapter
    The mounting holes for the Hopkins Adapter # 47595 measure 3” apart on center. The 7-Way Round pin connector is something that is found in the States but unfortunately is not compatible with the European wiring. Since European wiring is completely different than what is found in the States there aren't really any adapters that we know of which that can just plug in and make the different wiring systems compatible with each other.

  • How to Wire Up a 6-Way on a Hawk Trailer
    Since trailer wires colors are not always consistent among manufacturers the best way to figure the functions of each circuit is to test each circuit individually. There are two ways you can do this, the easier way is to get a car battery and run a jumper wire from the positive side of the battery to each of the wires in question. When you put current on each circuit you should be able to see what functions activate, which will tell you what does what. I would recommend you label each...

  • Which Circuit of 7-Way Trailer Wiring is the Reverse Light Circuit
    I can easily help you identify the reverse circuit of your 7-way but we don't know have access to the wire colors. The great news though is the reverse light circuit of your 7-way is the center pin which is the easiest to identify.

  • 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.

  • How is the Adapter 7 Way Blade to 7 Way Round Pin # 47595 Configured
    I will be happy to tell you how the pins are configured on the Adapter # 47595. On the 7-Way blade side, if you are looking at the face of the plug: 1 oclock position = tail and running lights 3 oclock position = left turn and brake lights 5 oclock position = ground 7 oclock position = output to trailer brakes 9 oclock position = right turn and brake lights 11 oclock position = 12 volt power Center position = reverse lights/auxiliary circuit On the 7-Way Round pin side, if looking at...

  • What are the Funtions of 7-Way Blade Style and 7-Way Round Pin Trailer Connectors
    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,...

  • 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 Go From 4-Way on Vehicle to 7-Way Round on Trailer
    It won't be pretty but you would need two adapters. You would need the part # 30717 to convert the 4-way to a 7-way blade and then the part # 47595 to convert the 7-way blade to 7-way round.

  • Need Adapter for a 6-Way Round Pin on a 1968 Chevy C-50 to a 7-Way on a Trailer
    To go from a 6-Way round pin trailer connector on a vehicle to a 7-Way blade style connector on a trailer, you will need to use adapter # 47435. A 6-Way can be wired in 2 different ways, the brake out put could be the center pin or the 12 volt could be the center pin. You may need to re-pin the adapter to match your set up.

    Based on the information you have provided, I see no reason why the Hopkins 7 Way Blade to 7 Way Round Adapter # 47595 would not work. Another option would be to remove the 7-way round pin connector from your camper and replacing it with the Hopkins Endurance 7-Way Trailer Connect # HM48500.

  • Solution for Towing a European Trailer with a US Spec Tow Vehicle
    The only solution I could help you with would be the third option you listed. You would want a trailer side 7-way like part # H20042 to wire up to an EU socket found local to create an adapter to use your US spec vehicle with EU trailer wiring. I attached a chart that labels the functions of the wires on this connector. The Adapter 7 Way (Blade) to 7 Way (Round Pin) # 47595 that you referenced is not an adapter for EU wiring nor do we offer any adapters for EU trailers or vehicles.

  • Running Light Only Works in Reverse with the Hopkins 7-Way Blade to 7-Way Round Adapter # 47595
    The Hopkins 7-Way Blade to 7-Way Round Adapter, # 47595, was designed to be rewired. This adapter was designed to be rewired because there is no industry standard when it comes to wiring a 7-way round style trailer connector. If your tail lights come on when the vehicle is put in reverse, then, at the back of the 7-way round end, switch the yellow wire with the green wire (see video). If that is the only issue you have come across, then that should fix your problem. If you are having...

  • Troubleshooting a Right Turn Signal on a 7-Way of a 2000 Ford F-150
    First thing you should do at this point is test the 7-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring. That would mean that problem is either due to a ground issue or a short issue. Make sure that the trailer side connector is clean...

  • 7-Way Blade to 7-Way Round Adapter Recommendation
    It sounds like you need a 7-way adapter. If the pins on the 7-way of your truck are blades and the pins on your trailer are round pins then you would need the # 47595. If the setup is the opposite of that you would need the part # HM47425 that you referenced.

  • 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...

  • 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.
