Excellent Quick Delivery
When you are
driving a Test or NASCAR Hauler you need replacement parts very quick, just like a pit stop. Thank You very much for the rapid delivery.

A great little heavy duty plug that I use to connect my car to the rv when towing 4 down.





Entailer has the website to find and deliver the parts I have needed to repair my trailering needs. Easy to find my same parts that needed replacing.


parts purchased from for my homemade cargo trailer

So far so good. No issues with this product


This is a well engineered and solidly built trailer socket. Made from sturdy cast metal and not from breakable plastic. I like the removable terminal block with barriers between the pins to prevent inadvertent shorts. Most importantly, the split terminals are made from brass so they will not corrode plus provide very good conductivity compared to steel. I’ve read the terminal block is replaceable, but haven’t seen a link as to where to buy one if that is ever needed.


Had everything I needed to wire my Jeep Grand Cherokee. YouTube videos exist to help. There some surprisingly difficult places to route the wires along the frame.


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



Great experience with etrailer as always, Product delivered quickly and in was good quality.

@David Thanks, we really appreciate your business!


these are just what need, I just got them in the mail about 30 min ago, could not find both parts at local farm store. these look like what I used when I was younger, they worked great then so should be good now. I thought I had a problem, but it was just me. Steve


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.


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

Steven J.


Has worked great. Does what I need it to do with no problems.


Excellent product. Well made and easy to install.


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.


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.


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.


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.


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.


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


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

Walt K.


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


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 .


Looks like great quality and the company is great to work with!


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.


Good quality connector. Wish blue ox would use this instead of plastic



Still working!


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


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.


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

  • Completing a Flat-Towing Setup for a 2018 Ford F-150
    Yes, the Blue Ox Base Plate Kit part # BO74FR comes with all the hardware you will need for installation in addition to the safety cables that secure the base plates to the frame. You can see everything that is included with this base plate kit in the attached photo. The Blue Ox Tail Light Wiring Kit part # BX8869 will work for you as long as you do not have LED tailights. You can add a 6-way round trailer connector to this kit with part # PK11609. If you do have LED tailights then I recommend...

  • Parts Needed to Flat Tow 2011 Jeep Wrangler with a 2012 Call of Duty MW3 Edition Bumper
    So based on my research, the Call of Duty MW3 Edition bumper debuted with the 2012 model year, which is why there is no mention of fits for any base plates on a 2011 Jeep Wrangler with that bumper. Since the Jeeps are otherwise the same, it seems likely the Roadmaster Direct-Connect Base Plate Kit # 1439-3 will work, but there is just no way to guarantee it. The d-ring adapters you added may be a better option so long as your bumper is rated by the manufacturer for flat towing, and it...

    I have included images below of the 6-Pin # PK11609 and the 7-Blade # C58155 connectors that you will be wiring. I do recommend using the positions rather than trying to go off the wiring colors as the colors can vary. You can use a Test Light # PTW2993 to verify the wires are in the correct places on your current 6-pin connector.

  • 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.

  • 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.

  • What Gauge Wire will Fit Into a Vehicle Side 6-pole Round Trailer Connector
    Both the Hopkins # HM48420 and the Pollack # PK11609 will accept a maximum of 12 gauge wire, so neither will accommodate 10 gauge. To get aux power and ground to your 6-way, you will want to run a length of 12 gauge wire like our 12 Gauge Primary Wire # 12-1-1 or # 12-2-1.

  • 6-Way Fifth Wheel Trailer Connector for 2011 GMC Sierra
    If your Sierra already has the 7-way connector installed in the bed, you can use an adapter to convert the 7-way to a 6-way. Hopkins makes a great heavy-duty adapter. If the center pin on the 6-way connector on the trailer carries the power to the trailer brakes, use part # HM47085. If the center pin is used for an auxiliary circuit, use part # HM47083. If you do not have the connector in the truck bed, I would recommend part # 50-97-410.

  • What Wire Gauge Can Be Used with Pollak 6-Pole Wiring Socket PK11609
    I believe you are referring to the Pollak 6-Pole Trailer Wiring Socket - Vehicle End # PK11609. If you are asking about a different product please just let me know. 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. I have attached a couple short video reviews below that you might also find helpful.

    Your semi-truck is going to have separate turn signals from the stop lights and your gooseneck trailer is going to have combined turn signals and stop lights.

  • How to Match Up Wiring Connectors Between Motorcycle 4-Pin Square and Trailer 6-Way Round
    Thanks for the photos, Russ! The square 4-Pin plug you have on your motorcycle isn't common so you'll need to cut it off and rewire it to the Pollak 6-Pole # PK11609 so they match - you'll just have to match up the pins per function. You might also need to install the Curt Powered Tail Light Converter # C59236 if your motorcycle has the brake light circuit separated out on it's own. In this case you'll install the Curt wiring and then cut off that 4-Way and install it to the Pollak 6-Pin.

  • 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...

  • 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.

It all depends on what works best for you. If you only tow the one trailer then converting the vehicle makes more sense.
