Say goodbye to fragile trailer connectors with the Pollak Heavy-Duty, 4-Pole, Round Pin Trailer Wiring Socket. Its robust metal construction with zinc die-cast ensures durability and a secure link between your trailer and towing vehicle. Designed to withstand the elements, it makes setting up and taking down a breeze for all your towing adventures.
Keep corrosion at bay with concealed terminals on this socket that protect your connections from the harsh outdoors. The dielectric grease coating adds another layer of protection, preventing resistance and voltage drop. With this on your vehicle, you’re ready for anything the road throws at you.
Forget fumbling with frustrating setups. This socket features a spring-loaded lid that keeps dust and moisture out, ensuring your connections stay clean and reliable. The easy wire insertion style makes installation straightforward, so you can focus on getting on the road.
Adaptability is key. The Pollak socket accepts wire gauges up to #12 and is engineered to fit seamlessly with the Pollak Heavy-Duty 4-Pole Round Pin Connector (PK11402). With a color-coded wiring arrangement for effortless setup—white for ground, green for right turn and brake lights, yellow/red for left turn and brake lights, and brown for tail lights—integrating with your existing system is seamless.
Prepare for your biggest towing jobs with a voltage rating of 12-24 volts and a current rating of 35 amps. Whether you're using it for a utility trailer or connecting a tow vehicle and motorhome, this socket is built to handle the heavy-duty demands of your setup reliably.
Good qaulity and durable
I've never really liked Flat-4 type connectors. Unless you leave them dangling, they usually require that you crawl under the vehicle to connect them. (...Murphy's Law dictates that this will always be when it's raining or snowing).
This Pollak 4-pole round socket, along with a Tow-Ready harness, and matching trailer connector, provides a neat, factory installed look, that's more convenient, and durable.
My orders from etrailer arrived quickly, and with great seller communication. A+
Hi George, The adjusting star is too small & needs to be bigger - tools slip off easily - the groove is too shallow. They're wearing good.
Heavy built. Very much wish it had a cable clamp on the backside similar to its male equivalent. As it is all the strain on the wiring/cable is supported by the terminals themselves.
I've got that trailer that has had one tough life. Yep, hundreds of gigs, PA and sound equipment rolling in and out, the heat, the cold, the sun, rain, and snow. Chicks, guitar players and drummers, you know, all the things that beat the hell out of a drum! Thank the music Gods for etrailer.com! The place to remedy the ills that trailers need in times of harsh environments, tough crowds, tin-ear'd musicians, and you ain't nothing but Hound Dogs!
Thank you guys. You are the best
Excelent Quality! Parts was a perfect fit for the factory location.
Works great
Ordered this along with the Remote Controller, however, the controller would not slide onto the 4 poles. Tried to squeeze the poles and they split leaving one side on each pole. Ended up grinding each partial pole tip so the remote could slide on it. Don't know how long they will last before I have to order another 4 prong connector. They are working fine for now.
Quality is good but buyer beware - you must use a compatible plug, as all round 4 pins are not the same. This particular socket has two different size pins (3/1) so be sure to buy a matching plug or pick a different receptacle.

Thanks for your review and your business, Pete. I am glad you brought this up! The PK11404 is used in conjunction with PK11402.
The round pin socket is good, the only issue is it is very easy to install the hookup wire upside down due to the key is not very pronounced in the socket. The socket needs a deeper master key slot.

Still working no issue again which it had a better master key slot
This replaces a failed one that was made of rubber and did not hold up to repeated plugging and unplugging.

It has worked very well. We sold the RV and now have the BlueOx tow bar and brake system for sale.
I like this Pollak brand. Their connectors always seem to work the best. I wish this 4 pole connector came with a rubber boot for the back. I couldn't find one, even at the Pollak website. I ended up taping it up really good with electrical tape.
I've used the Pollak pk11404 on a Jeep for a couple of years. The Wi. winters can be a beast on the standard flat 4 wire plugs. This plug came thru winters like a champ. I've traded cars so this 1 is for the new Chev. Great Job Etrailer
Needed to complete the connection, does require some drilling of holes for mounting screws, but makes a solid connection. Spring loaded cover also locks the connection together. Is easy to use in all weather conditions, and with metal construction is heavy duty and long lasting
Poorly manufactured. Fell apart after 3 months. The inside wire connection came loose and pulls out of the body of the socket. Had to rebuild the item and secure inner socket with sheet metal screws. It still works but I expected better quality and longevity.
This wiring socket has a look and feel of quality. Appears very durable. I also purchased the male socket and it locks in place tight. I'm using this to connect wiring from my RV to the Jeep while towing.
Product is just what I expected. I'm going to use this to plug a salt spreader to the truck. The factory harness is pretty beat up so this will make plugging it in much easier. Extremely fast shipping. Great place for your trailer needs. Anything I need from now on will be from Etrailer.
Found this company by accident. Living outside of a large city it can take me most of a day to obtain the parts I need. This works well as I can order my parts and move on to the next project. The parts so far have come fast, as stated and packaged well for the travel to my shop allowing me to get the project done or back into service.
NOTE: Check out the etrailer videos online, They are a great resource for the beginner into the industry or the seasoned professional that wants a refresher.
Item is as described and good heavy duty quality. S&H was very reasonable and delivery to Hawaii took less than a week.
I highly recommend etrailer.com and will personally shop here again.
Just what I wanted! A HEAVY DUTY 4 pin connector for my tow vehicle. No issues or problems.
It was a replacement for an old trailer and it works just like it is supposed to.
Worked perfectly I plugged it in simply plug and play. I havnt had any issues with the connections. 10/10
Exactly what I needed, very well constructed. Will use to proivide lighting to RV dinghy vehicle and needed easy hook-up which is what it provides. Should provide many years of use.
Products arrived earlier than promised. Very easy to install.
So far, they are working better than the plastic OEM products that wore out after 2 years of use.
Only possible improvement would be to include a colored wiring diagram for people who not be as knowledgeable about electricity.

It sounds like you were able to get this part to work for what you needed it for, however, the remote item # BDW20144B is a replacement for the bulldog winch BDW10012 and it will plug right into the winch.
