Video Transcript for Hopkins 7-Way to 4-Wire Flat Heavy-Duty Trailer Coiled Wire Adapter Review

Hey everybody, Ryan here at etrailer. Today we're gonna be checking out the Hopkins trailer wiring adapter. So this is gonna let you go from a seven-way round type connector to a four-way flat type connector. What this is gonna do is really simple. It's gonna let you plug into your vehicle's seven-way round type connector and bring it down to a four-way flat. So the signals that it's gonna send back to your trailer will be your taillights, your brake lights, and your turn signals.

Now there's a ton of different adapters like this, or similar to this, available and you know, what this one will work good for is just about any situation really, but I could see it really becoming useful for those of you that tow multiple different trailers, you're not real sure what trailer you're gonna be pulling type deal. If your trailer wiring's kind of short, maybe you have a a real long ball mount or if your seven-way's in a kind of a funny spot like our 4Runner here today. So believe it or not, the seven-way is all the way kind of buried way over here on the driver's side. And even with this trailer's wiring, like, that's a pretty good length. You know, that's not short by any means.

There's no way that would even come close to being able to plug in. So by utilizing our adapter, I'll be able to, maybe, if I get to it here, plug it in, that'll give us all that extra length we need and then some, honestly. So I might be able to just kind of drape this over and allow you to make that connection and not have to worry about it coming disconnected when you make those turns and stuff, too. Since this is coiled, it'll stretch out when you make the turns or if you need that length and kind of gives you the freedom to kind of set things up how you want to. If you we're to stretch this cord out completely, the length that it's gonna give you is three feet.

So that should be more than enough for just about any situation you might find yourself in. If you don't think you're gonna need any additional length like this and you're looking for something a little bit different, what I would suggest is a real simple adapter like this. This is a seven-way, and then on the back there's just a four-way that'll allow you to plug in there. So that's always an option for you as well. And there's different variations to this as well.

So we just did one of these. It's a seven- to five-way flat type connector on this end. So if you got a a five-way type flat connector on your trailer, you can always check that out and that'll allow you to hook everything up and get it going. As far as the quality of this, I'm not gonna lie, I'm usually not super crazy about Hopkins stuff but like I said, I've been doing several of these wiring adapters and I actually like 'em, I think they're well built. The wires feel thick, you know, it has a good coating on it that's, you know, not super stiff but not super loose, so it'll stretch out when you need it to and whatnot. But more importantly, the connectors are really nice. They're not that brittle plastic like you'd usually see. They're almost a, almost like a hard rubber, I guess, if that makes sense. And what I like about 'em too is everything is sealed up up nice, for the most part. Like on some of the cheaper ones you'll see the wires kind of come in and it's just kind of cinched down. That's not the case with these. It's all molded almost, I guess you could say. And I like how on the ends they're somewhat reinforced, you know, like drops back some. 'Cause a lot of times it'll happen over years, you know, without this here there's no support there. Then the wires end up getting kind of tossed around like that and cause some connection issues, so this should hold up for some time. I like the thickness on the four-way side too. It gives you a good, you know, spot to actually grip and get it plugged in. So pretty impressed with it, actually, should definitely hold up. Gives you a little dust cover, too. So really no reason that this should give you any issues for quite some time. Other than that, at the end of the day, you know, there's really not a whole lot to it. Pretty simple part, but can be a great solution for a lot of people who are needing to get their four-way trailer hooked up to their vehicle that has a seven-way round style trailer connector. And that'll finish up our look at of the Hopkins seven to four-way trailer wiring adapter.

Hopkins Heavy-Duty Trailer Coiled Wire Adapter for 7-Way to 4-Wire Flat - HM47065

Average Customer Rating:  4.8 out of 5 stars   (169 Customer Reviews)

This heavy-duty, coiled cable adapter is compatible with a 7-way RV blade trailer socket on the vehicle and adapts it to work with a 4-wire flat connector on the trailer.

by:

Works, exact fit, high quality, coils tight so max of about 3.5’ perfect! Heavy duty wiring, great waterproof connections.



by:

Needed a longer connector for my vehicles. Both have 7 way plugs, but I use a trailer with a 4 flat plug. The coiled adapter works great for both of the vehicles. Very good product if you need some extra length and the fact that it has the coils makes for a better appearance.



by:

Item was just as I anticipated. It looks good, works great, and the delivery was as promised. E Trailer is a good place to do business.

Works as well as the day I bought it. No complaints. A great product.



by:

Will work great around the water. Always backing the trailer to the river with multiple turns and have enough stretch to stay connected!



by:

Excellent quality and very sturdy const ruction.



by:

I needed a trailer lite adapter for my 4Runner to my boat trailer. This adapter was just what I needed and it worked great, just as expected. It's also high quality and reasonably priced. Keep up the great work etrailer.

Still works great, I also use it when I tow my utility trailer.



by:

haven't hook it up yet. Looks like this solves the extra wire cable to light up the cargo carrier. No more wire cable hitting the road surface and no more cable wrappings around the long trailer hitch.



by:

Bridges the gap nicely between the utility and small boat trailers I use and the offset light socket on my 2009 4Runner. Really heavy construction; it feels like it'll last a long, long time.



by:

Useless- how many towed vehicles are within the three foot length of this cable? Do not order this with the wiring kit for your towed vehicle that lets you use the vehicles tail lights instead of the magnetic lights. The tow bar between your motorhome and the "toad" is around 4' long. I'm not sure what this can be used for.



by:

Very well put together robust at both ends easy to attach at either connection not flimsy at all.



by:

This is just what I was looking for. It works perfect for my trailer and car carrier. It's heavy duty. The shipping was fast. I looked at other ones,but none as good as this for the price.I will buy from trailer again.



by:

I have yet to make a connection from truck to trailer harness, however I anticipate functionality since the HM47065 Adapter is very well constructed. Thank you



by:

The tow-harness and components appears quite well made. Fit was perfect, installation was easy, and tested and worked the first time. The instructions, however, may have been more specific to earlier Pilots, thus were not entireley clear and caused some delay in installation.



by:

Heavy duty works great



by:

Products were delivered with very short wait time.

Adapter cable HM47065 is a replacement of the original cable purchased for towing in 2012.

Socket HM48480 is a replacement of the socket that was on the motor home when purchased used in 2012.

They haven't been installed yet, but I don't expect any issues.

Thanks



by:

Good quality product



by:

This was a prompt and satisfactory transaction with delivery in three days. The merchandise is a quality trailer light connector. I highly recommend etrailer.com for anyone needing trailer accessories.



by:

Perfect design! The bright color acts as a reminder not to leave it plugged in when I'm done trailering. The coil design extends and contracts with the movement of the truck.



by:

Perfect for your new SUV with a 7 pin electrical connector, so you can connect to that 4 pin trailer.



by:

Haven't got to use adapter very impressed with the construction of this product, will be perfect for what the use will be. Have a newer and larger truck my trailer connections are too short with out the wire adapter.



by:

This was perfect for me!



by:

Product worked as described and is well made. Like the coils as this prevents the wire harness from dragging on the ground while allowing harness to stretch during turns.



by:

I purchased one of these back in 2010 when I bought my new Nitro boat. This is one of the best products I have ever used. I have never had any issues with it and I can leave my lights hooked up when I back in with no problems with water. I purchased this one in 2017 due to someone stealing mine from my trailer in one of the parking areas so I suggest securing it in you vehicle. Again a great product.



by:

I have ordered from etrailer five times and each every time I am impressed. The prices are the lowest out there, shipping is exceptionally fast and their selection is beyond equal. I won't buy from anyone else, why should I?



by:

Exactly what I wanted. Shipping was fast as always. Amazing place to shop!

  • 5 Foot Long 4-Way Flat to 7-Way Flat Adapter
    Not exactly, but I can come up with a 5 foot long adapter that has a 7-way male on one end and a 4-way female on the other. Basically you would need the # 18045 and then to plug in the # PK12716 into the corresponding end and you would be good to go.

  • Is There a Different Sized Plug Version of the Hopkins HM47025?
    The simple answer to this is going to be no, because trailer connections adhere to an industry standard in order to ensure compatibility between different manufacturers and for end user convenience. Trailer connector adapters like the current # HM47025 will be the same size as something like the Hopkins # HM47065 -they are all going to have the same dimensions assuming they're the same type of connections (7 flat, 4 or 5 blade, etc.). For these reasons, the 7 way end on the any adapter...

    I would be happy to help! To flat tow your 2007 Hummer H3 behind your motorhome you will first need a base plate kit of which I recommend the Demco Classic Base Plate Kit - Fixed Arms # DM9518193 which will pair perfectly with the Demco Commander II Non-Binding Tow Bar - Victory Series - RV Mount - 2" Hitch - 6,000 lbs # DM9511012.

If the GMC has 2WD, it has to be towed with a dolly with the rear wheels off the ground. When flat towing or dolly towing, the battery does need to be disconnected. You can use a Roadmaster quick battery disconnect part # RM-766. The Roadmaster battery disconnect allows you to wire in...

  • 7-Way to 4-Pole Wiring Adapter for Audi Q7
    The wiring in many German autos will not react well to the presence of LED lighting on a trailer, or even in an item like the 7-to-4 Adapter # 47345. I recommend you try another 7-to-4 adapter that does NOT have built-in LED test lights, such as # PK12716, if your trailer does NOT have LED lights. If it DOES have LED lights the instead use # C35FR. You can also use a coiled cord type adapter like # 787196 or # HM47065.

    No worries, we can help you!

If you have just the wire leads then you can make a more reliable permanent modification to the trailer so it matches your truck's connector without the potential reliability issues that can occur when using adapters and the extra connections they create.

  • 7-Way to 4-Way Adapter Recommendation
    I have a better solution for you, but technically the part # HM47065 that you referenced would work go from a 7-way to a 4-way connector. What would be a better solution would be the part # PK12716. This will plug right into your 7-way and will allow you to connect your 4-way to it.

    It looks like you purchased the # A57WB, and most standard 4-Pole flat connectors will fit this 5-Pole flat connector- so you may just be able to plug it in not using the end port. However, you could also just get a new cord with a 4 flat on it with the Hopkins Heavy-Duty Trailer Coiled Wire Adapter for 7-Way to 4-Wire Flat # HM47065.

    To power a license plate light you will need to locate the running light circuit of either your vehicles trailer connector or of this LED Light Kit # 98174LED to power the light and then you would need to ground the light to the ground circuit of your connector. To convert the 7-way connector to a 4-way you could use a Hopkins Heavy-Duty Trailer Coiled Wire Adapter # HM47065. This would plug into your 7-way and give a 4-way to operate the # 98174LED.

The flat-tow wiring harness will take input from the motorhome's lighting signals and then apply these to the towed vehicle.The flat-tow wiring harness is going to be composed of two components, the umbilical which bridges the gap between the tow vehicle/toad and the trailer side flat-tow wiring harness which is what gets spliced...

    You will not need to remove the Roadmaster Direct-Connect Base Plate Kit - Removable Arms # RM-521448-5 when you explore off-road. You will want to remove the removable arms just to prevent them from getting damaged. The Roadmaster Direct-Connect Base Plate kit is heavy duty and it also fits snug against the bumper and rock guard.

    I'm going to give you 2 options in this particular situation. The first is the Pollak 7 Pole to 4 Way # PK12716. It will work if you 4way plug from your trailer is long enough to reach the plug with no chance of pulling out. The one I recommend is going to be the Hopkins Heavy-Duty Trailer Coiled Wire Adapter # HM47065. It is a much more robust cord that is coiled so it won't drag. The main reason I prefer this cord is on most all trailer connections the end is secured by some type of latch....

You'll also need safety cables like # RM-643 and a Tow Bar like the Roadmaster Falcon 2, part # RM-520.

    For a 7-way to 4-way adapter I recommend the Pollak 7 Pole to 4 Way Connector Adapter # PK12716. This adapter has a non-corrosive nylon shell so salt water would not be a concern. If you need an adapter that is more than just a plug and has some extra cable, I recommend the Hopkins Heavy-Duty Trailer Coiled Wire Adapter # HM47065.

You'll also want to check your hitch to confirm its tongue weight (TW) capacity and to check your owner's manual to verify the truck's TW rating.

But we do have 7-way to 4-pole cord-type wiring adapters too, similar to 7-to-5 adapter # A57CCB, such as # HM47065, and # C57271. We also have plug-style adapters such as # HM47570 that convert a 7-way to 4-, 5- and 6-pole, all in one product. All wiring adapters are shown on the linked page.

This could be the reason that you're experiencing an issue when the blinker is engaged when it's connected. I'd also check to make sure that none of the wires going to the right hand blinker are damaged and touching any metal on the vehicle. If you check the wiring and still...
