Pollak 6-Pole, Round Pin, Trailer Wiring Socket - Vehicle End - PK11609

Average Customer Rating:  4.7 out of 5 stars   (105 Customer Reviews)

Establish a secure connection between your trailer and your towing vehicle with this 6-pole, round pin, wire-insertion-style socket. Zinc die-cast socket is self-grounding and includes floating pins for easy alignment and maximum pin contact.


Fits perfect! New Toad, New baseplate, new factory plug-in lighting electrical harness but it came with a four pin plug incompatible with old jumper coil harness. Easy installation. I added 2 large washers under sheet metal screws used by BlueOx to attach and reinforce the mounting holes as some reviews had cracking around baseplate holes. Same type used on Prior Toad never had any issues but why not spread the load with larger washers.


It appears to be a very durable unit. My previous plastic unit broke.

There could be better pictorial installation details that correlate with the written instructions.


Replaced original cracked plastic plug (4 years old) that came with blue ox tow system. Love the strudy metal. Unfortunately, the diameter of the oepning for the plug is just a bit too large. Plug fully seats so that tab on underside of spring-loaded lid engages, but the weight of the coil cord back to motorhome tilts the plug down a few degrees (due to too-large opening). This position disengages the retaining tab on the outlet's lid, and vibrations can easily pop the plug out. I'm currently running with 3 zipties to hold the plug in firmly while I figure out a replacement. Not going to keep cutting zipties off at every stop. I'm surprised that no one else seems to have run into this problem.


I gave the poor rating for the same reason that I had to buy this socket to replace our original one. The pin that holds the lid and spring slides out and you lose the lid. The replacement when received already had the pin slid out past one side. This time I slid it back and put a dab of jb weld on each side to keep it in place.


parts purchased from for my homemade cargo trailer

So far so good. No issues with this product
Steve i - 08/17/2018


appears to be quality product, fair price and quick delivery. thank you eTrailer


etrailer is an awesome place to do business with on items required to tow your vehicles behind a RV. My order was shipped immediately and very well packaged. I absolutely love the online instructions which simplify the installs. A+++++


Works great.

Great, no issues.
Jose R - 05/31/2022


Used this at the front of my toad. Mounted it under the license plate (used a spring loaded bracket). Works great never a problem.

Has worked great. Does what I need it to do with no problems.
Steven J - 02/10/2021


Excellent metal connector used to replace a plastic connector that failed. Very heavy duty construction on this metal connector that should last forever. The brass split male connectors are also very well made heavy duty construction.


Exactly what I needed! Easy install works beautifully! Thanks


I purchased this part to replace an similar one from Roadmaster which has a plastic housing. The Roadmaster front car plug was part of a wiring kit. All wire connectors rusted heavily in less than a year making the plug unsafe to use aND can no longer be serviced. I live in North Florida, maybe the Roadmaster products should only be used in Arizona.
This new part will most likely rust similarly, so I will apply a heavy coating of liquid electrical tape. And hope for the best.


Good quality trailer plug. I used this for the lighting connection on the tailgate of a stacker trailer (race car trailer) and it saw a lot of use over the past year. None of the pins have broken or bent, no connection issues at all. Very satisfied.


Yes ma'am, every thing is good. I just told a friend of mine about y'all, he has a few trailers to repair. He'll probably be ordering from you soon. Thanks for checking on me :-)

Yes both products still perfectly. It has been a pleasure doing business with you.
Scott - 10/11/2017


This product works perfect for our vehicles we pull our small trailer with. It allows us to also use it on our motorcycles and maintain a clean look instead of having a wire and plug hanging down. etrailer is punctual and efficient with customer care, answers to questions and delivery. Keep up the good work ET


Quality build, easy to wire up, still in great shape a year later. Do recommend.


order was received relatively quick worked fine


I needed a conector that would be built to hold up to weekly use and this item did not disappoint. I installed it on my farm tractor and my fuel transfer tank to make refueling my tractor quick and easy. Found this to be a quality built connector at a good price and supper fast shipping.


Excellent product. Well made and easy to install.


This worked just fine . Couple of weeks ago took trailer from central Ohio. To Pigeon Forge . Tn . Every thing worked fine . I put this on to go out west . I pulled my camper out to Washington state , Down to Disneyland , back route 66 .


I got everything I needed to wire my Ford Ranger to be able to pull it behind my RV. The instructions were simple so I had no problem installing. It's saved me a great deal of money by being able to do it myself.


eTrailer is the greatest! Great selection, best prices, fabulous communication from order to delivery AND fast trackable shipping.
All the reasons I keep buying from them.
Oh yea, the plug is just what I wanted


Used this as a replacement and it worked very well. The wiring has been improved for ease of use. I would recommend this adapter


Perfect replacement for existing connector. Easy to install, and solid when mounted.

Excellent replacement. Easy to install, working great. Love the pollak product.

Easy installation and works as expected…. Quick, safe delivery…

  • Mounting Hole Dimensions of the Pollak 6-Pole # PK11609
    I pulled a Pollak 6-Pole # PK11609 from our warehouse and found that the mounting holes are 2-3/4 inches apart and the diameter of the tube on the back of the connector is 1 inch.

  • How to Gain Access to Pins on Pollak 6-Pole Round Pin Trailer Wiring Socket PK11609
    The Pollak 6-Pole Round Pin Trailer Wiring Socket # PK11609 does have a small Philips type screw to hold the rear collar in place. You will need to remove this screw completely and pull/twist the collar to remove it for access to the pins for attaching your wiring. Don't feel is always smarter to ask a question than not.

  • Dimensions of 6-Way PK11609
    On the 6-way part # PK11609 the section behind the mounting flange where the wires attach is 1-3/8 inches in diameter. The distance between the mounting holes is 2-7/8 inches, overall width of the front is 3-1/4 inches and overall height is 2-1/8 inches.

  • Is There a Reverse Wire on 6-Way Connector
    As you can see by the accompanying diagram I added, a 6-way such as the Pollak # PK11609 does not have a function for reverse lights; that function is on a 7-way so you would not connect the wire you referenced to your trailer connector. A 6-way has the following functions: 1) Tail/Running Lights 2) Left Turn/Stop 3) Right Turn/Stop 4) Brake Controller Output 5) 12V Power 6) Ground. I have also added a link to a help article on wiring I highly recommend checking out.

  • Solution for Gooseneck Trailer Brakes that Lock Up When Connected to Tow Vehicle
    If your trailer has a 6-way connector like a lot of gooseneck trailers do the issue is that the 12 volt power and brake output circuits are sometimes swapped since some people wire them both ways. The solution is to swap the two circuits if you find yourself in a situation where the brakes lock when a trailer is connected. On a 6-way the circuits are the pins in the center and 10:00 facing opening of socket on tow vehicle.

  • Troubleshooting 6-Way Trailer Wiring That Displays Constant Power on Trailer Brake Circuit
    A 6-way trailer connector can be wired in one of two ways. One way is to have the center pin wired to carry the +12V trailer power feed. The other is to have the center pin carry the trailer brake circuit. It sounds like you may have a vehicle and trailer that do not share the same wiring configuration. If this is the case you can install a vehicle side socket like # PK11609 and wire it to match the pin assignments on the trailer. An article on trailer wiring is linked for reference. Another...

  • How Does 6-way Harness part # PK11609 Come Apart to Attach Wires
    If you fastforward to the 1 minute mark of the install video I attached for the 6-way harness part # PK11609 that you referenced you'll see that there's a screw that holds the back of the connector to the main housing that you'll need to remove and once it's off you can push out the inner section and attach the wiring to it.

  • Parts Needed to Convert a Motorcycle and Trailer 5-way Connector to a 6-way
    You will want to first cut off the 5-way of your motorcycle and then wire a 6-way in its place. The sixth circuit will be for the brake controller output. For a vehicle side 6-way round you would want a Pollak 6-Pole # PK11609. Now for your trailer with a 5-way on it you will want to install a 6-way as well. You would want to use a Pollak 6-Pole # PK11604 like you referenced for this. The brake controller circuit will not be used on this 6-way. Now your motorcycle has a 6-way on it that...

  • Installation Location of PK11609 For Flat Towing Wires on 2021 GMC Sierra 1500
    I recommend using the installation bracket # PK11771 to install the # PK11609, but the location where you install it really doesn't matter as long as it's on the bottom half of the front end on your 2021 GMC Sierra 1500. I recommend going down to the area near where your base plates are mounted as there will likely be part of the frame you can use to screw the bracket into; you could also attach the bracket to the fascia and it would also be secure.

  • Troubleshooting Trailer Lights not Working with a 4-Way to 6-Way Adapter on a 2005 Toyota Tacoma
    Before attempting to install a new 6-way connector, I would recommend using a circuit tester, # 40376, to test the connectors on your 2005 Toyota Tacoma and on the trailer that you are using to see if something is not wired correctly. When you have the adapter connected to your 4-flat connector, test each pin for proper function. I would also recommend testing each pin on your 4-flat connector as well, just so we can determine if the problem is on your 4-flat connector, the adapter, or...

  • Completing the Wiring for a 7-Way Trailer Connector
    The black wire coming out of the 7-way connector should be connected to 12 volt power from the vehicle battery. The blue wire connects to the trailer brake feed circuit coming from the brake controller mounted in the vehicle. If you need to run these wires for your connector you will need a 40 amp circuit breaker, item # PK54540, to attach the black power wire to the positive battery terminal. You can use the Wiring Kit for Electric Brake Controllers, item # 5506 and the 40 amp circuit...

  • 6-Way Recommendation for Trailer and Tow Vehicle
    For the trailer side 6-way you would want the part # PK11604 and then for the matching socket you would want the part # PK11609. We don't carry any grommets for the vehicle side 6-way that you referenced and the part # 118152 would be a great choice for storing the 6-way.

  • Installing 6-Way Trailer Connector on Motorhome
    To wire a 6-way trailer connector to your motorhome you are going to need to use a circuit tester like the handy Cordless Circuit Tester # PTW2979 and match the connector to your wires by function. The reason you need to do this is because color codes are not universal and there is no database we have access to with wiring color diagrams for specific years, makes and models of vehicles. Even if there were, the wiring could have changed from previous owners so it would be unreliable, hence...

This particular socket is designed to handle up to 12 gauge wire, but the most commonly used size wold be the slightly smaller 14 gauge that's found inside the Jacketed 6-Wire # DW04906-1, which is sold by the foot.

  • Adapting a 4-Way Flat on a 2010 Toyota Tundra to a 6-Way Flat on a Yamaha Boat Trailer
    A 6-Way flat trailer connector is not very common. To make sure we are talking about the same thing, a 6-Way flat would look just like a 4-Way flat, only with 2 additional pins. Because a 6-Way flat is so uncommon I recommend replacing the connector on the trailer with a more common 6-Way such as # PK11604. Then on your 2010 Toyota Tundra you can replace the 4-Way with a matching 6-Way, # PK11609. Or, even better, you can install a 4 to 7-Way adapter on the truck using # 37185 and replace...

    We do have a 4-Way round adapter but it goes to a 4-Way flat, # 47465.
