When you need a solid link between your vehicle and trailer, this Pollak 7-pole socket keeps things simple and dependable. It’s an RV-style connector that follows the standard 7-blade pin layout used across the industry, so it works with most trailers right out of the box. Whether you’re running electric brakes, reverse lights, or a 12-volt charge line, each circuit lines up exactly where it should for a clean, consistent signal every time you plug in.
Swapping out a worn or broken socket doesn’t have to mean rewiring. This connector plugs directly into the existing round harness on the vehicle side—no splicing required. It’s built as a direct plug-in replacement for standard USCAR-style wiring, so if your old socket’s lid is broken or corroded, you can just unplug it and snap this one in.
Towing puts connectors right in the line of road debris, rain, and dust. The Pollak 7-way socket comes with a spring-loaded cover that seals tight when not in use to keep contacts clean and dry. The heavy-duty plastic housing resists cracking and corrosion, helping ensure the pins stay protected so your trailer lights and brakes get reliable power whenever you hit the road.
Every pin on this 7-blade connector follows the standard configuration—left turn/brake at 9 o’clock, right turn/brake at 3 o’clock, running lights at 11 o’clock, brake output at the 5 o’clock pin, ground at 7 o’clock, auxiliary power at 1 o’clock, and reverse in the center. That makes testing or wiring repairs simple using any basic circuit tester. Once connected, you’ll have all seven functions ready for towing.

Part was an exact fit and with fast delivery! Pricing was also spot on. Thanks!
Product has worked fine for a year. It was cumbersome to install without a clear video on exactly how the factory plug on the vehicle socket was released in order to plug in this connector socket. But once I sussed that out, I had no problems installing this.
For some reason, my Chattanooga built Volkswagen Atlas has an oddball (to us Americans) factory connector. This adaptor fits perfectly and looks like what VW should have installed in the beginning.
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.
Great business to work with. Done many years with them and will continue.
Thanks
The parts I purchased were those recommended on the blog, and they fit my 2021 ID.4.
Exactly the part i needed. Always great service, and follow up.
Perfect Fit Great Product, Highly Recom mended
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! :)
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.
Madison did a great job helping me when the part i originally ordered was not available. She got another part on the way asap. I always enjoy working with etrailer and their representatives!
Fit my 2021 Audi Sq5 exactly like OEM part. Easy replacement, great quality.
Exact replacement for OEM and appears to be of equal or better quality
I have a Ram 3500, this trailer connector was a perfect match. Easy install and works great.
The Pollak Replacement 7-Pole, RV-Style Trailer Connector Socket was a perfect replacement. It took about 5 minutes. This socket works great with no issues.
Perfect replacement for the connector I cracked by accident.

1 year later and it is still working perfectly. Still looks as good as the day I installed it.
Very quick shipment and connector was better than my broken part! Now looks like original equipment!
Perfect fit for my 2017 F350 in-bed fifth wheel connctor. Mounting bolt pattern matched and the backside electrical connector snapped right in.
Works as advertised. True plug and play
It took too long for us to wait. Had a customer ready to pick up vehicle. Product looks great and customer service was excellent. We will definitely order again.
Pollack products are great, I've had them for years, attached right on the B&W hitch with the bracket they supplied with the hitch, fast shipping, Thanks
Installed and tested and seems to work perfectly. To be perfectly honest, my vehicle was NOT on the list of those that this part will fit. But I saw on another post elsewhere that someone had had success with this and I thought it was worth the gamble. I just installed this myself in about 20 minutes, thanks to a YouTube video. The dealer is quoting 70 bucks for this part plus installation which I heard can be as much as $200 more. I just did it myself in 20 minutes for $18. Thank you so much. Check out my pics.

High-five on the install, Coach! I'm glad that even though it wasn't on the list that you were still able to get everything installed smoothly :)
Absolutely an original OEM product. A perfect quick replacement for GM trucks. Etrailer.com provided fast service too!

Working great!! Direct replacement for the original. I did not remove the cord of travel trailer and pulled the original plug completely out of the truck bed. This one was all plug and play.
