Features to know about

Long-Lasting Durability: Metal Construction Over Plastic

Sick of replacing broken plastic trailer sockets? The Pollak Metal 7-Pole RV-Style Trailer Socket is built with heavily plated metal construction that resists weather and corrosion, making it a rugged and reliable replacement. This strong build ensures it outlasts plastic sockets and offers years of dependable service, even in the harshest environments.

Stay Connected with Confidence: Weather-Resistant Design

Worried about moisture and dirt wreaking havoc on your wiring connections? The Pollak Metal Socket features a vinyl insert that keeps out dirt and moisture, along with a spring-loaded cover and stainless steel spring that helps keep your connection secure. This design not only protects the connection but also makes sure your trailer’s lights and brakes work properly in all conditions.

Simplified Wiring: RVI Standard Color-Coding

Not sure which wire goes where? The Pollak Metal Socket simplifies the process with standard RVI color-coding, making it easy to connect your tow vehicle to your trailer. Whether it's the white ground wire or the blue electric brake wire, installation is straightforward and hassle-free, ensuring you don't spend hours on what should be a simple task.

Keep It Secure: Spring-Loaded Cover with Latch

Loose connections are a thing of the past. The spring-loaded cover with a stainless steel spring and safety latch ensures that your connector is firmly plugged into the socket. This means less chance of disconnects during travel, providing peace of mind on bumpy roads or extended trips.

Always like metal in cold country.

Works well



by:

Great product. Much better than the plastic ones.



by:

Excellent product. Looks to be something that will actually last.



by:

Easy to order, product was exactly what we ordered, and had the product in out shop very quickly.



by:

This one looks good. Replacement receptacle for a broken plastic unit. Hookup went easy. Solid construction, good feel.



by:

Great RV receptacle. I prefer metal housings like this as opposed to plastics that can break at low temps. They shipped promptly as promised. Thanks eTrailer!



by:

Poorly designed junk. For starters, the color markings on the back are incorrect order. Once you ignore that and wire it in correct order, the plastic body will not go far enough in for the set screws to lock it into position.



by:

Excellent service thanks



by:

My Toyota Tundra came from the factory with a weak plastic trailer socket that caused a "trailer disconnected warning" intermittently while towing. I replaced it with the Pollak Metal socket and haven't had a problem since. Highly recommend this part.



by:

good product made of steel not plastic,made in tiawan ,better than china,would like one made in USA. maybe etrailer can find more parts made in USA i would be willing to pay more.its time to take back our country,the USA.

Thanks for the feedback, happy to hear you are pleased with your vehicle connection. If you need the trailer plug, that is available as Part # PK12702. It is linked above as a related part.


by:

Finding the metal female connection can sometimes be difficult, but it is well worth it . No breaking, cracking from stress and heat expansion. I recommend these .



by:

Easy to install and works great. Can always rely on etrailer for great parts, fast shipping, and the best price around.

Everything seems to be working well.



by:

Product is much better than the plastic version. The receptacle has a very strong spring on the lid and a hook to lock the trailer plug into it.
The plug is galvanized and not stainless how ever, so it will corrode and rust in the Wisconsin rust belt eventually. After 1 year how ever it is fine.
I bought the metal version for out custom work trucks that I build for our company. The protective lids on the plastic ones were getting broken. The metal plug is more durable and has solved that issue.



by:

Still very happy with this unit I sold that truck But remove the trailer plug from It & reinstalled it on my replacement truck & still use it,
this was worth the effort.



by:

Heavy duty metal not plastic



by:

Great Product! Hasn't let us down yet.



by:

I am very grateful to etrailer for always providing excellent service. Orders are received in a timely and accurate fashion. The quality of their products is superb. All items ordered function as described with no malfunctions. The trailer and vehicle wiring connectors I have ordered were a great replacement for old existing equipment that was constantly failing.
Very professional company. Very high quality products. I look forward to continued business with them.



by:

I needed a connector for my trailer and got it over night best service ever highly recommended.



by:

JENA D i've used these plug ins for my shear that attaches to my skid loader. Were in the iron and steel business, my wife irons and i steel. I've used these plug ins for about 19 years now and have had real good luck with them.YOU got the order right and they arrived on time who do i talk to about getting YOU a raise. Thanks again Donnie



by:

Good quality, excellent product.
The
only thing they missed IMHO is to put a rubber gasket to the cap.



by:

Going to rewire my pickup truck trailer circuit , this is last piece I needed. This is high quality plug for my r v . Thanks

by:

great product super durable can't go by the colors on the back of the connector though

  • Troubleshooting No Power To Trailer Brakes When Trailer Connected To New GM Truck
    When you hooked up to the GM trucks, did you notice if the truck said trailer connected? The towing computer on the newer GMC trucks is kind of finicky and if it did not recognize the trailer, or the trailer was not setup in the system it will not send power to the trailer brakes. If you were getting the no trailer connected message you will need to use the 7-Way Trailer Adapter # C57003 which has load resistors and will help the computer detect the trailer. If the trailer was not setup...

  • Difference Between 7-Way Wiring Diagram that Uses Red Wire and Purple Wire
    There are actually two ways that 7-way wiring colors are commonly seen. One uses a red wire and the other a purple. The circuits they represent do vary though. So check out the updated diagram I attached to this page and most likely you need to wire the connector up like the center one.

  • Troubleshooting Trailer Running Lamp Circuit on 2020 Chevy 1500
    GM refers to that circuit as the 'Trailer parking lamp'. The fuse is in location # 41 in the fuse box in the engine compartment. After replacing the fuse, you'll want to closely examine the running lamp circuit on your trailer. You'll want to locate and repair the short that caused the fuse to blow, before plugging the trailer in for the first time. Otherwise, you'll continue to blow fuses. I'll link to a troubleshooting article that you might find helpful.

  • Trailer Running Lights Do Not Work but Brake Lights and Turn Signals Do Work
    It could be a tow package fuse on the vehicle. Use the owners manual to find the locations of fuses/relays related to the tow package wiring to check them and replace as needed. If the issue is not a fuse or relay then you can test the vehicle side trailer connector using a circuit tester such as # PTW2993. Turn the vehicle headlights on and use the circuit tester to test the pins on the connector at the back. If there is no power on the running light pin then there is a break or loose...

  • Troubleshooting No Power on the Blue Brake Output Wire from a Brake Controller
    To determine why you do not have any power on the blue brake output wire, I recommend starting at your brake controller. First, make sure the brake controller is on and receiving power. Most brake controllers have 4 wires, blue (brake output to trailer brakes), white (ground), black (12 Volt power from vehicle battery), and red (stop light switch). If your brake controller is not on, make sure the black power wire is connected to the vehicle battery via a 20 or 30 amp circuit breaker....

    The trailer wiring on the newer trucks like what you are experiencing on your 2019 GMC Sierra 1500 and the new Ford trucks with the "smart tow" package are proving to be challenging for reasons like what you found where the truck doesn't want to show a trailer connection. The easiest solution you'll have will be the 7-Way Trailer Adapter # C57003 which was designed for German vehicles towing trailers with LED taillights that has load resistors built into it. Basically you'd install this...

  • Which Fuse Provides 12-Volts to 7-Way Connector on 2009 Chevy Silverado 3500 Diesel
    If the 12-volt pin on your trailer connector isn't working, you've got a missing or blown fuse or the wiring connection at the fuse box under the hood wasn't finalized. You're looking for a 40 amp fuse, located in position # 68 in the fuse box under the hood. The fuse protects one of the nearby power studs on the side of the fuse box, which is where the wire that provides power to the 7-way should be connected. If it's not, you can find the wire bundled up under the master cylinder (see...

  • Left Turn Signal Works on a 1996 Ford F-350 But There is No Power at the Trailer Plug
    The first step to troubleshooting your issue would be to eliminate any obvious causes. First, check your trailer connector for dirt or corrosion. Dirt and corrosion can prevent a signal from reaching the pin on the connector. If you see corrosion on the exterior of the connector, then it may be possible that the corrosion or dirt and penetrated deeper into the connector. I would recommend replacing the trailer connector if this is the case. Be sure you test each pin on the trailer connector...

  • Troubleshooting A Non-Working Running Light On A Boat Trailer
    Hey Paul, Stop/turn signal light functions typically use the same wire and the running lights are on their own. You'll want to go to the passenger side and check the running light wire for power with a multimeter # PT89ZR. If you aren't receiving power at the light then you'll trace that wire back to the power source looking for damage and checking for power until you find where it stops. With this being a boat trailer I would typically just rip out the old wiring and start with new...

  • Troubleshooting Trailer Lights That Don't Work With Power Flowing to It
    Hey Ray, this sort of thing happens quite a bit actually. Usually what's happened is that there is either a short in the circuit, or there's an issue with the ground. I'd recommend checking the grounds and make sure they are connected securely, and attached to a clean bare metal surface. You'll also want to make sure there is no dirt, corrosion or debris on the connectors as that could also be causing your issue. Next, If the grounds and connectors look good, I'd check the wiring and...

  • Troubleshooting Rear Clearance Lights of Trailer that Stopped Working
    Hey Jaret, most likely all of the lights that aren't working are carried by a single wire that runs to the back of the trailer so that would indicate to me that the problem is that wire is damaged somewhere between the connector and the lights. So you'd need to trace this circuit to find and fix the problem.

    From your photos you have a 7-blade connector on the RexAir and a 4 pin round connector on the 1997 Suzuki Sidekick. The blue wire in your photos is a 4 pin to 4 pin connector which will not work to connect the RV and the Suzuki.

  • Troubleshooting Non-Working Running Lights On A 2013 Jayco Jay Flight Swift SLX 184BH
    Hi Jose, If you had a short in the wire it's highly likely that you just blew the fuse for the running light circuit and need to replace the fuse in your tow vehicle. Worst case scenario you could also have burned up the wire or damaged the lights and would need to replace them all as well, but I doubt that's the case. I would start by checking the 7-way to see if each light function is coming through. If not check the trailer specific fuses for your vehicle and replace as needed. Once...

  • How to Determine Functions of Trailer Connectors
    The function of trailer connectors are often similar, as evidenced by the accompanying diagram which shows the functions of 7-ways. It really depends on how the connector is wired; that said, there is an easy way for you to determine the functions of a connector. All you need is the Hopkins Tow Doctor Trailer End Test Unit # HM50928 in order to test the trailer-side 7-way. I have also added a link to a help article on trailer wiring which I strongly recommend checking out.

  • Troubleshooting Trailer Wiring, Could Fuses of Vehicle be At Fault
    If the trailer wiring of your vehicle uses factory wiring then a fuse could be responsible for the circuits not functioning. If the wiring is a kit that taps into the taillight circuits of the vehicle either using a tee connector or wire taps then it would most likely be the connection to the vehicle wiring or corrosion on the pins of the connector. I attached a help article on trailer wiring for you to check out as well.

  • Should There Be Continuity Between Ground and Brake Output Pin On 7-way Connector?
    You should have continuity between the 5 o'clock brake output pin and 7 o'clock ground pin in your 7-way connector with the brakes applied. I recommend turning the trailer brake controller to its max setting and having someone apply the manual override while you check for continuity. If you do not have continuity then there is either an internal issue with the controller, or one of the grounds has gone bad. Let me know what you find and I would be happy to go through some troubleshooting...
