Average Customer Rating:  4.8 out of 5 stars   (156 Customer Reviews)

This molded, 7-way, RV-style, trailer-end connector lets you replace a damaged wiring harness on your trailer.

by:

Love the molded design, notice the wires are different colors from standard trailer wiring, but work great.



by:

Shipped out of stor immediately. Got it in 2 days. Fantastic experience



by:

Installed a Hensley Hitch on my travel trailer and needed to extend the connector due to the setup. Superior quality. Wired directly to the junction box and junked the old pigtail.



by:

Good quality wire. It's working well.



by:

I do appreciate the service I got from you guys. I talked to several of your associates over the course of my order and they were all extremely knowledgeable and helpful.



by:

Ordered this a year ago for a home made trailer I built. It has worked flawlessly with no problems. I will not hesitate to buy this product again. Thanks etrailer

Well built and works very well highly r ecommended

i did a complete rewire and added brakes to frt axle and after towing quite a few thousand miles to catch fish i would do it again



by:

As always the products from etrailer.com arive quickly and are excellent products. I always go to etrailer first knowing I will get the best product and at the best price. The Hopkins 7-way trailer wire connector is top notch. The rubber is pliable and the fitting itself is of top quality. Thanks again for the great and timely service. ,Wayne

My 7 wire connector works as well today as the first day. Excellent quality as always from etrailer.com



by:

Great product!



by:

The wire works as expected, bu BEWARE, the wire colors are not standard. etrailer should attach a notice with the shipment. The brown wire goes to green, the green wire to brown, the red to yellow, and the yellow to the backup light (purple).
I wish I'd realized that BEFORE I installed it and trimmed the wires inside my wiring block!!

Fortunately, because I don't have a backup light on the trailer, I could move all wires left by one post, so that the wire lengths still worked. Otherwise, it would have caused real problems.

Sam B~~Thanks for your comments. There are two standards in the industry for 7 Blade cables. The standard that this product is wired to is the RV standard. The second standard for the 7 Blade cables is newer than the first but is becoming more popular. We do manufacture 7 Blade cables to both of these wire color standards.



by:

Quality product. Nice heavy gauge wire for the power, ground, and electric brake circuits. The only complaint I have is the unique (non standard) color coding of the individual wires. This would be so much simpler if they used industry standard color coding on the conductors in the cable.

I liked the Product at first but 1 day short of a year later the cord outer jacket has separated from the plug itself rendering it completely exposed to the elements. Cord does not have a 1 yr warranty. I will not be reordering this cord. Hopkins is always my go to for trailer wiring components but no longer will be for 7 way pigtails. Cord has never been abused in any way and only gets light use.



by:

I used this product to update/repair the rather shabby OEM wiring harness. It worked perfectly. I love etrailer!

David M.

Still working perfectly



by:

Not my first order from etrailer and definitely not my last. My only complaint would be in the packing of small or fragile items loosely in a box with heavier items. One of the trailer light mounts was broken when it got here. No other issues though.

We do our best to package our orders so that they will arrive to you in good condition. I will send this to our shipping department manager for review.



by:

This was exactly the product we wanted and it arrived exactly when you said it would. Thank you very much. We will be using this on a fifth wheel homemade trailer.

It worked great. Thanks.



by:

I purchased a female ( TRAILER SIDE) wiring harness and a wiring connector box for connecting the trailer body wiring and trailer plug. This combination works perfectly with my 8 TON goose neck trailer an one ton dual wheel truck. I use Hopkins wiring connectors and accessories on all my farm equipment. and have been very satisfied with them.



by:

Both the 11' trailer connector and the Junction box were exactly the items that my project needed. They were used to rewire a gooseneck horse trailer.



by:

Used this on my Arctic Fox TT to replace the original pigtail which never properly fit the Hopkins connector on my Toyota Tundra. This one is the real deal, much better mechanical and therefore better electrical connection. Not overly tight, yet snug and secure. Should have installed this years ago! Highly recommended.



by:

Very simple hook up. Heavy duty connection which has never given me any trouble. This wiring is now on my sons trailer. I installed the same product on my trailer in 2005 and its still 100 percent operational.would recommend to anyone.



by:

Great addition



by:

This cable was of good quality, however, the wiring was different than the typical 7-pin RV connectors. I had to move wires around to make it work on my application.



by:

Wasn’t wired correctly and cut off the female end and used another connection to make it work properly

When wiring the Hopkins connector you will want to make sure that you are wiring for function and not solely basing it on color. Be sure to utilize the chart on the product description page for the functions and colors of the harness.



by:

the wire colors do not match brown was for left turn signal the only two wires that are right are the white and blue so if you purchase this product make sure you
check it first before you wire it in or you will cut it off and rewire it

Etrailer Expert

There is more than one accepted wire color code convention for a 7-way trailer connector, which is why we list the wire color code in the product description above.



by:

I use 4 trucks to pull our horse trailers . 2 with 8' beds, 1 has only the plug under the bumper. the other 2 trucks are short bed trucks again 1 has only the plug under the rear bumper.
This cord works well with the different trucks . I had 2 trailers that needed replacement cords. Color code is the same on the Sundowner and the Exiss.

I love etrailer order stuff and good service fast del. thank you

  • Parts Needed to Add Brakes to 1992 Coleman Arcadia Pop-Up Camper
    Based on your manual indicating 7" brakes it is probably a 2,000 lb axle. That should be a 4-bolt brake flange on the axle as well. Try checking your axle tag to see if you can verify this. The capacity may be listed, or it can be found with the serial number. You will need the following parts to add brakes: -Dexter Trailer Hub and Drum Assembly for 2,000-lb Axles - 7" - 5 on 4-1/2 # 8-257-5UC3 -Dexter Electric Trailer Brake Kit - 7" - Left and Right Hand Assemblies - - 2,000- to 2,200-lbs...

  • How To Install New Trailer Wiring On A 2015 18 Foot TWF Trailer
    The wiring of your 7-way connector on your 18' TWF trailer will depend on what standard you are using for your 7-way connector on your 2020 GMC Sierra 1500. This 7-way connector matches your vehicle's wiring. I recommend the Hopkins 7-Way Molded Trailer Wire Connector - 11' Long, part # HM20048. The wires are molded to protect from rust and corrosion. This wire connector has three different wire gauges to match the different currents. I also recommend using dielectric grease, part # 11755,...

  • Junction Box and 10 Wiring Pigtail Availability
    We do have a separate Junction Box # 3430001-JBK you can combine with the Hopkins 7-Way Molded Trailer Wire Connector # HM20048. This harness is 11' long which will give you approximately 10' of cord outside the junction box.

  • Parts Needed to Add Brakes to 2023 Big Tex 35SV Single Axle Trailer
    Yes, the # 84556UC3-EZ is the correct hub and drum assembly and the # 23-26-27 will work for brakes. However, you might want to consider the Dexter Nev-R-Adjust # 23-468-469 for brakes instead. Since they are self-adjusting, you won't have to worry about remembering to manually adjust your brakes. For a 7-way you can use the Hopkins 7-Way Molded Trailer Wire Connector # HM20048. If you want a junction box use # 3375601101. Then for a breakaway kit we have the # 20400. I have attached...

  • Recommended Heavy Duty 7-Way Trailer Wiring That Will Last
    A standard Bargman 7-Way cable like the 11' part # HM20048 will have a similar quality as the Hopkins equivalent. If you're wanting something a bit more durable then I recommend the Bargman 7-Way, RV-Style Connector w/ 6' Heavy Duty Insulated Cable # 54006-057. This wiring actually comes with a 1-year limited warranty which initially doesn't sound great but for the world of wiring it's pretty good. Attached are some review videos for you to check out!

If you prefer a longer connector, the same item is available in an 8 foot length as part # H20036 or an 11 foot length as part # HM20048. Please note that the color codes on these molded connectors are different from those usually found on a trailer. The wiring code is on each of the product pages. If you don't have some already,...

    So you have a tow vehicle that has a 7-way connector on it and then a trailer that has a 5-way? What you would need to do is remove the 5-way wiring and install a 7-way with a lead like part # HM20048 which is a 7-way with 11 feet of harness. I attached a picture that has a diagram that has how a 7-way normally wires to a trailer.

  • Does The Black Wire On My Hopkins 7-Way Power My Running Lights
    The Hopkins 7-Way Molded Trailer Wire Connector - 11' Long, part # HM20048 is for a 12v circuit. This is the accessory circuit. Oftentimes it is used to charge a trailer's battery.

This kit comes with ring terminals, heat shrink wrap, and a junction box. The box will allow you to secure your 5th wheel's wiring in one water tight organized location.

I have added an image below showing the wiring terminal positions for the 7-way. Depending on your vehicle your 12 volt power may run all the time or only when the ignition is turned on.

  • What Does Black Wire In Hopkins 7-Way Molded Connector HM20048 Do?
    The black wire on the Hopkins 7-Way Molded Trailer Wire Connector - 11' Long # HM20048 you were looking at is for the 12v power circuit that typically gets used to trickle charge an on-board battery, or for powering an electric trailer jack. If you do not have any accessories on your trailer that use the 12v power from the tow vehicle you can just leave the wire taped up or in the junction box un-used. I included a video of the # HM20048 for you to take a look at.

  • Parts Needed To Convert Triple Axle Boat Trailer From Hydraulic To Electric Brakes
    Hello Edward, I can definitely point you in the right direction. Generally, we do recommend using hydraulic brakes for a boat trailer, since electricity and water do not mix well. If you want to add electric brakes, you will need electric trailer brake assemblies, hub/drum assemblies, a 7-way trailer wiring harness, an emergency breakaway kit, and an electric trailer brake controller for your vehicle. In order to recommend the correct parts, I will need more information on your trailer....

    It isn't the breakaway battery as that doesn't factor into the power of any of your lights or your electric brakes. The issue is either with the wiring itself or your 7-way trailer connector. So start by checking out the wiring, specifically the grounds, on your trailer to see if there is any damaged wiring, and that your ground are connected to clean, bare metal surfaces. If that is fine, it is almost certainly the 7-way connector being damaged or corroded and you will need to replace...
