This 7-pole, sealed, RV-style trailer connector plugs into the factory socket on your truck or SUV. Connector is an exact OE replacement on Chevy, Ford, GMC and Nissan.Worked out awesome. I bought this for a buddy for his used truck. The previous owners for what ever reason took it. Plugged it in and worked flawlessly.
It is a direct OEM replacement, easy installation. What I liked most was a real person answered my call and took my order, Katherine was very polite and knowledgeable. Thanks again. CJ
The 3 star rating is because this is not a direct replacement for a Nissan Armada. I bought this to replace the original socket on a 2004 Nissan armada. The hitch on the car says it is a Nissan hitch. I did not notice that the original socket mounted as a twist lock type and the bracket had no mounting screws when I ordered this socket. In defense of the manufacture and distributor of this socket the description did not say it was a direct replacement for an armada the assumption would be that the hitch would be the same as a titan. This was no big deal for me since I had a drill and bits to drill mounting holes and used # 8 sheet metal screws. Just have to be careful to drill the holes the right size so they self thread properly. I have been looking to see if there is a direct replacement for the original socket but can't seem to find one not even on Nissan's parts web site so I guess you just have to do what I did. I didn't think to take a video of the installation but I have included a picture of the finished install.
product from Pollak is always great but they packed it with steel couplers and destroyed it
This is just what I needed Price and fast delivery Thanks will trade again *****

Works the. Way I need. Thanks
I had to replace the socket in my truck after I forgot to disconnect the plug when setting up my camper 1 year ago. Since then, I've connected the camper 35 times and pulled it over 6,000 miles. I have had no issues at all with the new socket.
The transaction went great. Delivered on the time I was told good product
It fit right up to my 2016 Porsche Cayenne diesel. A very simple installation.
This is it!! If you have a Porsche Cayenne with a tow package (mine's a 2017) and you're wondering why the wiring "connector" that came from the factory is just a plate with nothing to plug in to... This is the thing you need! It fits the holes in the mounting bracket perfectly and plugs right into the harness coming out of the car (after you carefully release the little clip holding the clip connecting the plate to the harness (no, that's not a typo). I also purchased a matching 7 to 4-pin adapter, so I can easily connect to either. And etrailer had it all... and made it easy. Quick shipping, just as promised. Love e-Trailer! :)
Still working after a year. Performs as expected. Easy to install.
It fit perfect and was literally plug and play.
After redoing my trailer wiring harness to put a socket in the bed of my 1995 F250, I used this to replace the old socket in my bumper. Saved me having to do more splicing and hard wiring in the old socket.

After a year of use, this is still working great. I don’t use it a lot as most of my towing is of the 5th wheel using the in-bed connector.
Easy to install and has worked every si nce
Hi, I am a ASE Certified Automotive technician for 30-plus years. I have to say these parts are Factory quality, the option for Direct Fit everything plugs right into the wiring harnesses fits as if they came as original equipment with the vehicle and the same quality. When ordering parts if you call and speak to an operator that extremely helpful and actually know what's going on. And their tech support this extremely knowledgeable.
Nice fit to my factory harness. This was a replacement for the factory hitch mount. I decided to drill a hole and mount in the bumper like I’ve seen on other vehicles. This makes for a convenient and protected location.
This is the original plug and play. For VW SUV's this does the trick. I recommend using some anti-seize on the bolts that secure this into the mount. I have this on both an Audi and a Porsche both work great. The picture shows what the car some with so you simply plug this unit into the factory socket and secure with 4 machine screws.
Wrong Pollak product. needed Pollak 12-705 6-24 volts Female (truck)
The right adapter, fits Audi q7 factory tow package. 1/3 the price of Audi part. Fast shipping, etrailer is the place for reasonably priced trailer parts.
Thanks George
Quality unit. Easy installation. Replaced the oem perfectly.
This part fit perfect.
Arrived as advertised. Good product. Th anks.
Direct replacement for factory socket.
Fits the custom bumper cut out perfect, looking forward to installing.
I was surprised that my 2021 VW ID.4 had a hitch receiver but no receptacle. This fit perfectly.
Work great!

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
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.
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
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.
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.
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
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.
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 great and looks great. Get compliments on the hitch.
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.
Fit perfect just would like a pigtail for the part that comes from truck
This was a drop-in. Literally unplug the wiring harness off the blank, pop out the blank, pop in the new connector assembly then plug the wiring harness back into the connector. Honestly took less than 4-minutes. Awesome product. My local hitch install company wanted $150 just for the install of the connector.
Fast shipping. Nice quality product

Products still working great.
Super fast shipping easy installation looks better than factory plug love the 7way and 4 way so no more dealing with adapters
I’ve had a great experience with the etrailer company. I fully equipped my 2022 Toyota Highlander which did not come with the factory tow package. I bought the receiver hitch, the wiring harness kit, a brake controller plus this special 7x4 pole connector, which did not come with the wiring harness, which only had.7 pole. I also bought a special bracket to mount the connector where it needed to go. Their service was great. Unfortunately they did not carry the Anderson weight distribution chain type hitch that I purchased from Anderson. They are a well run, customer focused Company that I highly recommend
Great product at a great price. It was an exact fit and looks great. I like having the ability to plug in my 7-prong plug on my travel trailer or the 4-pin plug on my boat, without needing an adaptor. Got super fast shipping too. Buying from etrailer.com was a win- win-win.
