Quickly and easily replace a damaged 7-way and 4-way, or add a new one to your vehicle with a factory tow package. The twist-in socket has heavy-duty weatherproofing and features a cover that opens 180 degrees.It was exactly what it said it was. Perfect replacement.
My original equipment had reached its life. This allowed me to get rid of a 4-way to 7-way connector.
Very pleased with etrailer, but product not as sturdy as original equipment.
Nice upgrade for a 2002 Escalade. It’s just so bulky I cannot fit a locking hitch pin anymore.
Easy installation. It took less than five minutes to install and it works great. I installed it on my 2004 Chevy 2500 HD.
This is the wrong wiring conector. Sent 40920 which is a twist lock. The one I need got the lock clips on the side. You just push in and it snaps in. Need dual 7 blade and 4 flat. What do you want me to do?

Once you receive the rest of your order, I would love to hear your updated feedback.
I bought this to replace the OEM part. Fit in the original bracket no problem. Works great. Especially like the 7 way/4 way connectors. No need for an adapter.

One year later and still works fine!
They worked perfectly and I received them in shorter time than anticipated which kept my project in forward motion
Nice product. Kind of a sloppy fit for my factory 2005 Avalanche hitch though. The 7 pin connector doesn't pin out correct but the 4 pin does so I'll go with that.

Wasnt a perfect fit, somewhat loose but still hanging in there. I like the dual connectors, eliminates the use of an adapter.
Product worked well. A slight modification to gap. A small amount on file work and connector locked correctly. I am well pleased with product. The plug worked as described and delivery was timely.

It was easy to install. Was exact fit for my 2006 Duramax. The 2 plug design is just what I needed, no more adapters required from hooking to any of my trailers. Item was delivered on time and without issue thanks to etrailer. Great job folks.
Install was a breeze. I’ve used the 4 pin flat connector and it worked perfectly. No more adaptor for me.

Recently purchased a trailer with 7 pin round connector and trailer brakes. The connector worked perfectly with the truck and trailer without needing any re-wiring
This was a perfect fit. I wish the website would have come up with this as the right one for my Suburban, and have notified them of this.
Went in easy and seems to be a perfect replacement for the broken one. As always, great customer serivice and a good product.

After a year, it still works great. Better than the OEM part, much sturdier and has the 4-flat connector built-in.
Still functions as intended. The 4 way has been convenient because I don't need to carry an adapter anymore.

I have used this 7 way and 4 way many times it is durable and will last many years.
Great product !Fit my 2009 trailblazer perfect. Installed under a minute
Easy plug and play, could be a little snugger fitting, but not a problem.
Recommend.

wiring time saver, good quality
I routinely tow a couple of different trailers. One has a 7 way connector, and another has a 4 way connector. I kept misplacing my 7 to 4 converter, so I purchased this as a direct replacement for my Yukon's factory connector. While it's nice to have the 7 way and 4 way there all the time, the plug fits a little bit loose in the factory socket. It should work fine, I just wish it fit in there tighter.
This connector was exactly what I was looking for. I wanted an "all in one unit" for my 7-way and flat 4 connections because of the problems associated with using a connector converter. This has worked out great.
I bought this for a base model 09 Silverado. Twists in place by the license plate for a clean look, ease of use, and no more dangling pig tail. I bought this for the 4-pin to use with my boat. I’d recommend this to any and everyone with an 09 Silverado
This has been the easiest trailer receptacle to install & the best one I have used. It’s nice not having to use a 4 way adapter!
Exactly what I wanted. Easy installation. Great service from etrailer! Would highly recommend this site!

We have to agree with you, Larry. etrailer is a great site with great customer service. Thanks for taking the time to write a review and rate the product.
It was easy to install and it has worked great!!! One plug for my boat trailer and one for my camper, all in one. Now if I could figure a way to haul both at the same time. :)
I always go with etrailer for any towing type stuff.
Exactly what I need works perfectly for all types of trailer wiring. Perfect plug and play for my 2008 GMC Acadia.
This is the product GM should have installed... I received this piece and had it installed in 30 seconds.
Twist out and unplug original 7 blade connector, plug in harness and twist in this one... never look for your 7 to 4 adapter again.
Good quality piece with gaskets and hinges that are far more robust than many of the competitors.

This 7- and 4-pole trailer connector eliminates the need for an adapter and allows you to tow a trailer with either a 7- or 4-pole plug. Socket connects to your vehicle's OEM wiring system and mounts with included bracket.The box arrived opened and damaged. My wiring harness was missing. When I called to tell them my wiring harness was missing they told me that it was shipping separately but could not tell me when it would arrive. I later got an email telling me all of my items were delivered and asked me to leave a review. I still don't have my wiring harness and will not have the hitch installed by this weekend like needed because I don't know if I am ever getting my wiring harness.not to mention the box had no padding around the hitch so it's all scratched up.

I am sorry to hear that your order arrived in this condition. I see that our customer service department is currently working on a solution for you.
Worked exactly how described, great replacement for my risty only bracket and 7 pin connector. Fits my 2006 Chevy Silverado 2500HD perfect, plug and play. Bought specifically because the bracket is included. And with both 4 and 7 pin connectors, I don't have to use an adapter anymore!
I am not sure how this bracket passed quality control. It sure is a good thing I'm not planning on using it. Really disappointing to see how quality is overlooked during the packaging process. This should have never left in this condition.

Oh! It is definitely not how we want the bracket to arrive to you. I will have our Customer Service team reach out.
It was easy to install and took care of the issue I had of one of the trailer light segments not working.
Easy installation and very helpful installation video.

One year later and no issues
This connector and bracket is a great product giving both 7 pin and 4 pin connections. I was able to reverse the bracket (making new holes) to allow it to fit behind the bumper cover piece that hides the hitch when not in use. The only drawback is that a wiring harness that fits the round 7 pin to the Buick Enclave rectangle plug is not available as a separate purchase. Had to buy an additional 7 pin outlet that came with the correct plug assembly and use that for my combo plug.
took longer to remove the factory cover than to instal the connector. worked as advertised. I would buy this again if ever needed
This thing couldn't be better. Easy mounting. Plug and play. I can now connect any trailer I want. Love it, love it, love it!

This was a major upgrade for me at the time. A year later, Ive hauled massive loads across the country, and this connector harness works perfectly every time
I bought this because I needed the bracket and it was the quickest way to get it they do not stock the bracket alone. We where installing tommy lifts and needed t move the original connector which was installed on the bumper.
Item received as described. It was simply plug and play. Out with the old, and the new was an exact replacement. Very satisfied.
This dual connector adds a professional looking touch to our tow wiring installation
The self tapping screws that come with the mount are junk,
The product is Good.
Came in on time. The parts were in good shape and fit perfectly.
Great product, it was just what I was needing to complete my project.
Here's some snaps of my Hopkins #40975 installation. I can confirm that it's an identical replacement for the 2014 Silverado 1500 trailer-light blank insert, no bracket required. It took me 30 seconds to plug the Silverado's OEM 7-pin round connector (located inside the blank insert) into the #40975 Wiring Kit and snap it into the cutout. Then I tested the flat 4-pin outlet of the #40975 with a 5 dollar 4-pin LED tester from West Marine, and all light functions tested good. Shweet! To remove the OEM blank plug, it helps to reach behind it and pinch the two spring clips holding it in place... same with the #40975 if it needs to be removed for some reason. When I ordered the part from eTrailer, your site had a comment, "This will not fit your vehicle. See below for compatible parts," or words to that effect. Maybe take a look at that and remove the comment, as the #40975 is an exact fit for 2014 Silverado 1500, no bracket needed. Thanks, eTrailer team!

Although I havent towed since installing the Hopkins Pollak wiring kit since I installed it a year ago, I have tested the 4-pin connector for proper function using a 4-pin LED tester from West Marine and it checks out okay. Recently I inspected the kit for water intrusion mentioned by one of the raters, and I found no evidence of moisture inside the dual-connector compartment. On installation, I did make liberal use of the dielectric grease that accompanies the kit. Good product, easy installation, and great price.
Fit and works fine. My old one was just the 4 plug so now I don’t have to use the adapter for 7 prong anymore.

Works fine- no issues.
Another easy installation old one out doing in 15 minutes
It came with it's own bracket, which is a plus. It was compatible with etrailer.com's part number C56357, which is also a plus. The self tapping screws being the only hardware coming with the item was a disappointment. I just installed etrailer.com's part number 76301 hitch receiver which has a mounting plate for brackets like this. The self tapping screws, which might have been effective, wouldn't have looked "professional." After finding some hardware which worked, it went on smoothly and fits well with the rest of the assembly.

This product has been working well for the past year. I feel this was a smart purchase.
Scratched my head for a while, trying to find a quality way to connect this vehicle end 4/7 wire socket to my trailer ready (almost) 2015 Audi Q7. Finally decided that it really didn’t need to be bolted, but could be hose clamped to the existing heavy duty Audi bracket.
Mounted it sideways with a 1” diameter and a 3” diameter hose clamp. Be sure to use a 3” clamp with lots of serrations that all it to tighten it down a lot.
You’ll need to drill out the small hole of the supplied bracket to allow a clamp to fit through it. The other hole is a slot, and works unaltered. Small clamp on bottom, large clamp on top.
You’ll also need to relieve a small spot on the trim piece to make room for the 4-wire door to o-en freely. This is marked as red on one of the pictures.
Looks good and should work good!

Good installation approach for q7’s. Keeps water from collecting in wiring junctions.
7 and 4-Pole Trailer Connector Socket does not fit my towing vehicle.
Today I just received my etrailer order #114979486, that consisted of: Curt T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector (ITEM # C56431) and 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket - Vehicle End (ITEM # HM40975) for my 2020 Ford Ranger. I easily installed the harness, but the Trailer Connector Socket does not seem to fit on the rear bumper, next to the license plate.
Last week, I chatted with etrailer customer support rep and I was assured that the connector Socket (ITEM # HM40975) would fit on my 2020 Ford Ranger.
This etrailer customer support representative referenced a previous Q&A Topic titled, "Can the HM40975 be used on a 2021 Ford Ranger". I was also assured that 2020 and 2021 Rangers have identically constructed rear bumpers.
Today, I spoke with a different etrailer customer support representative. This rep told me 7-Way Trailer Connector (ITEM # C56431) was not compatible with the 2020 Ford Ranger recommend reaching out to the manufacturer directly for more information.
I'm very frustrated!!!! Can I please get a solution to this issue ASAP.

I am sorry that this has been a frustrating experience, however I do have an answer for you. The Hopkins connector part # HM40975 is technically not a fit on its own for a 2020 Ford Ranger. The short reason why is that the Ford Rangers do not have the round US Carr type of connector to plug into. Now by adding the Curt harness part # C56431 like you did, does make that round connector that you can plug into the back of the Hopkins connector that will give you the 7 and 4 way you want. Since it is using two different manufacturer products together, I do encourage you to test the 4 and 7 way to make sure all the signals are working correctly. In theory they work together, however they are not tested. The issue is going to be that the bracket that comes with the Hopkins connector is not going to match with anything on the Ford Ranger to connect to. It would just be bolted to the bumper or you could also consider using part # C57202 to install it on your hitch.
Fast shipping. Nice quality product

Products still working great.
A very good option to cut down on rattle. This is a durable product that is fairly simple to install. My only complaint is the magnet to keep cover closed when not towing should be stronger. I am happy with the purchase and it looks like it will be useable for years.
Plug and play item,worked great
Really impressed with the Hopkins product overall. Seems very sturdy, and the install was very straightforward. Would certainly recommend this plug, and etrailer to anyone in need.
Perfect fit and very timely delivery. Had to replace the damaged oem plug. Took less than 10 minutes. The how to video was great.

You mentioned that you needed a dual 4 and 7 adapter that clicks in. I believe the connector that you are looking for is part # HM40975. Which is a replacement that would fit a 2021 GMC Sierra.
