Today we're going to be taking a look at part number 47465. This is the Hopkins Adapter. This is going to adapt a 4-round plug on your vehicle to a 4-flat on your trailer. The distance that we have between the two plugs, that's going to give us a measurement of about 5 and one-quarter of an inch with the overall length measuring about 8 and three-quarters of an inch. It's going to come with a dust cap to protect the terminals when not connected here on the 4-flat connector side. It's got a nice easy grip design on it. That way you always disconnect that dust cap when you're ready to make your connections. Here on the center section it has some tape that goes around the wiring.
This is going to keep the wires bundled up. It's also going to keep its flexible design. It's going to allow it to maintain that flexibility. Here on each plug, see you get the finger tabs on this side which is just for easy grip design and you got the grips on this side. So, it's got the easy grip design that's going to allow for easier connecting and disconnecting.
The 4-way flat can be mounted using a mounting bracket. Those are going to be sold separately. You can see a few different options underneath the related items on this product's product page. That's going to do it for our review of part number 47465. This is the Hopkins Adapter. It's going to adapt a 4-way round plug on your vehicle to a 4-way flat on your trailer.

the 4 prong plug has holes that are too small for my male 4 prong. I wish that was part of the description.
Made connecting my utility trailer to 1978 Champion RV very easy. The ability to re-position the wires on the terminals at the round end to match the wiring on the RV made this the perfect adapter. Had it installed and operating in less than 30 minutes. Now I can take the bikes and other large items camping without blocking the walkway inside the RV.
The adapter appears to be high quality. It fits as advertised in the original 4-round female location. I have not had a chance to use it for trailering yet, so cannot report on functionality.

After almost two years, the adapter is working great. Good fit, no problems.
The ordering process was easy and delivery was timely. However, I must have ordered the wrong product as the round 4-pin male end did not fit into the 4-pin round receptacle. Therefore, the product is useless to me. I was unaware that there was not a standard size for this item. It has ended up in my junk drawer.
This item is a perfect fit for my 4 way round motor home hitch socket wiring. I bought a new cargo trailer that has a four way flat. I did not want to change my tow vehicle plug. So with this adapter it makes life easier. I hooked it up and it works. I commented on some other products purchased from e trailer. Nothing but good to say and keep up the good work.
Thanks
I thought I was ordering the proper application, but it is not correct.
No fault of etrailer, I just made the mistake, but I think I can do some wire cutting and splicing and have what I need.
Good people to work with, good shipping, just my mistake.
Product is perfect for its application (trailer electrical system connection). Arrived quickly and was cost-effective, as well. Well pleased with the entire transaction and would shop here again, as necessitated by my needs.
Items is as described. I have a round four prong plug mounted on my truck but not all of my trailers have the round plug. Need this adaptor for my flat plugs.
Great product. I was trying to hook my utility trailer to my old k5 blazer and I needed an adapter to make the connection. So I got online and looks like I have a new place to buy trailer parts now. Arrived quickly and worked perfect. I would recommend George J trailer parts to my buddys.
Very satisfied with the product. Good quality, fast delivery. I have used etrailer for several products and have always been quite happy with their service.

Plug-and-play!
Fit our older 99 Hurricane RV harness perfectly. Allowed us to adapt to a Haul trailer rig.
I cant really review the products I have purchased, which consisted of various adapters for towing trailers, however I can tell you this place/site is amazing, they offer a wide array of products from A to Z, all under one roof, perfect for one stop shopping...their prices are very competitive and the service is outstanding!
Product was wired incorrectly. I had to take it apart and rewire it to work. Should have just bought the pieces at the auto parts store and made it myself. Paid $20 something dollars for express shipping. Waste of money. Prior to this I have been extremely happy with all my purchases.

Keep in mind, 4-Pole rounds are often wired in different ways. They werent as thoroughly standardized as 4 flats or 7-ways.
it works thanks
The product shipped right away and the customer service at etrailer is wonderful - they are knowledgeable and happy to assist. Thanks!
Not everyone carries this type of adapter. Glad etrailer does.
Everything was as advertised, and thank you Kaylyn R for your wonderful customer service. It took awhile to get everything installed, because of crazy events in the past year, but it all works great!
Have purchased products over the last few years from etrailer,and have always been satisfied with the service and the products. Will purchase additional needed items, and would recommend etrailer to my family and friends.
Great piece and well built. Sadly to my not checking correctly, I bought it thinking it would fit what I had already and it doesn't. But If in a pinch, I have it.
This works well because you can easily rewire the 4" round end to adapt to whatever pattern your rig was set up for...and end up with a standard 4 flat configuration.
It is not very long...and it doesn't really need to be, but a few more inches would be nice.
I'd recommend zip-tying whatever end is attached to your rig.
Package was not delivered. USPS is really bad at this time. Please don’t use them in the future.

great
Fit like a glove. Only trouble I had with it was it was way to short. Had to extend the wires.

It is very unusual for the four flat connector to be incompatible with your connector. Would you be able to send a picture? I know that it can take some elbow grease to connect the two.
