Video Transcript for Pollak Wiring - Wiring Adapters - PK12728 Review

Today we're going to be taking a look at part #PK12728. This is the Pollak trailer connector adapter. This adapter is going to plug into your 7-way blade style vehicle end connector and it's going to convert it for use with a 7-way round pin style trailer end connector. The housing here on this end is going to be made from a dye cast zinc construction, very strong and durable as well as resistant to corrosion and rust. This unit is going to feature easy grip design so here on the blade end connector you're going to have the finger tab right there. It's going to allow for quick connecting and disconnecting. On this end here, you're going to have a spring loaded lid. It's got a nice little finger tab right here so you can easily lift up on that and make the connection as necessary. The easy grips are a great feature to have.

They're going to allow for quick connecting and disconnecting. Then right here in between the plugs you're going to have about 8-1/2 inches of wiring. That's going to be protected with that nice wire loom protector on there so it's going to keep the wires bundled together. It's also going to protect them from any type of damage. Overall length of this unit is going to measure about 16 inches and it's going to have a voltage rating of 12 volts. That's going to do it for our review of part #PK12728. This is the Pollak trailer connector adapter.

This adapter does have a limited one-year warranty, however I wanted to ask you a few questions. Have you had the opportunity to test the seven way on the vehicle to make sure the brake signal is making it there and also testing the brake wiring signal on the trailer to see if it is making it past the seven way on the trailer?

Michael

Yes I have tested it,and I have also hooked the trailer to another truck that doesn’t require the adapter and it works fine.

I have sent the warranty return instructions in a separate email to you. You will receive it shortly.

Great service, quick shipping for 5 buc ks!!!

The adaptor did the trick. My friend had an older and different style connector on his older truck, so he put the mating connector on his trailer. His truck was down and we needed the adaptor to connect the trailer to my newer GMC to use the construction dumping trailer.

Of all the ones like this that they had on their site, I think I picked the best. This thing is excellent! Does just the trick. Good quality construction materials assembled into a solid product. Connection fits were snug as you would want. The time from order to delivery was shorter than they projected too! Very, very happy with this.

Fine. No issues. It stays outside in the weather and still hooks up just fine.



by:

All three of the products we bought had a good solid snug fit, insuring a good connect. We have them all connected and have used them for a few days with no problems. I am glad we found your site and it easy to locate the products/adaptors that we needed.

  • Troubleshooting Bargman 7-Way Plug Not Fitting in Pollak 7-Way
    Most likely the notch on top of the 7-way plug is damaged which is preventing the Pollak 7-way's lid from being able to attach to it. So easiest solution would be to go with a new Pollak 7-way plug with part # PK12706.

  • Is the Pollak Trailer Connector Adapter # PK12728 Rated For A Constant 40 Amp 12V Load?
    Both the Lance proprietary connector and the Pollak Trailer Connector Adapter # PK12728 will be able to handle a constant 12 Volt load. After reading the Lance Proprietary Connector information, it states that in order to "protect your truck's 12 volt system from overload, a 40-amp circuit breaker # 9510 should be installed at the power source under the hood". Both of these connectors will perform the same with a 40 amp circuit breaker installed under the hood. Check your vehicles owners...

    We have exactly what you need for an adapter to go from the 7-blade connector on your vehicle to the 7-round connector on your trailer: - Pollak Trailer Connector Adapter - 7-Blade Plug to 7-Pole Round Pin - Nylon # PK12727 or - Pollak Trailer Connector Adapter - 7-Blade Plug to 7-Pole Round Pin - Die-Cast Zinc # PK12728 The only difference between the two is that one has a nylon construction on the plug and the other is a die-cast zinc. I have added links to video reviews of both adapters...

  • Is There an Adapter for a 2006 Lance 845 Camper Factory Round 7 Way Plug?
    The Pollak Trailer Connector Adapter - 7-Blade Plug to 7-Pole Round Pin - Die-Cast Zinc # PK12728 will actually not fit the plug you have on your Lance Camper. This is due to Lance making their own style plugs every now and then. This has caused issues before and the best option will be to replace the plug with a more common style. The Pollak Black Plastic, 7-Pole, RV-Style Trailer Connector - Trailer End # PK12706 will plug into a standard 7 Blade plug, that your 2021 Sierra 2500 will...

  • 7-Way Round to 7-Way Blade Adapter
    Since your light plugs into a 7-way round you'd actually need the opposite adapter than the # F77R. Which for that you'd just need the part # PK12728.

  • Option For Connecting a Lance Camper Electrical Plug To A 2020 Ford F 450
    We do have a potential solution for you, but Lance campers use a proprietary plug, and there is not any adapter for your Lance camper that we are aware of. If your camper does use the proprietary lance plug, we recommend replacing it with a 7 way plug like the Hopkins 7-Way Blade Style Connector with Molded Cable # HM20041. This way you can simply plug in to the 7 way plug on your F450. We also recommend running your connections thru a junction box # 3375601101

  • Can Lance Truck Safely Be Rewired to Match Truck 7-Way Plug
    As long as you wire the 7-Way Round RV Style Trailer Connector # A7WCB to match the functions of your vehicle-side 7-Way (see attached) then you won't have any issues with anything form your Lance camper to your vehicle.

  • Recommended 7-Pole Round Plug & Play Wiring Harness Adapter for 2005 Ford Super Duty Factory Wiring
    It sounds like your 2005 Ford Super Duty was outfitted with the 7-way blade system which is the most common in the market today. To adapt your 7-way blade to a 7-pole round for your trailer, I recommend the Pollack # PK12728. This 7-pole connector is prewired to simply plug into your truck's 7-way plug. It has the # PK11720 connector you referenced but is pre-wired like you are desiring. A great mounting bracket for the # PK12728 is the # PK11771. I have linked all the above mentioned...

  • Replacement 7-Way for 2008 GMC Sierra
    A standard 7-way socket like the part # A10-7072VP would fit the round connector of your 2008 GMC Sierra that you need a 7-way for. We don't have access to the Lance pin out.

  • 7-Way Trailer Plug Adapter or Compatibility with Lance Slide-In Truck Bed Camper
    Lance does have a proprietary plug, but many customers see a standard 6-way or 7-way round and notice it doesn't fit their factory 7-way as well. I've attached an article to help if you have one of the 7-way or 6-way round connectors which we do have adapters for. If you have a 7-way round, then you will use adapter # 47595. If you have a 6-way plug then you will use adapter # 47549 or # PK12728. If you have the special Lance plug, I recommend replacing it with # A7WCB which would directly...

  • Compatibility Of 7-Pin Flat To 7-Way Round Trailer Connector
    A 7 pin flat connector is normally European. It will give you the same functions as a 4-way flat. To convert the wiring to make it functional with a 4 way, you will need the Roadmaster Brite-Lite Wiring Converter # RM-732. You can use a circuit tester like # PTW2993 to determine functions for proper connection. To get the other functions for your trailer 7-way, you will need the # ETBC7 kit and a brake controller like # 90195. If you are looking to adapt from a 7 round to a 7 blade,...

    The Tekonsha Prodigy RF Wireless Trailer Brake Controller # TK94FR needs to have a 7-way blade connector on both the tow vehicle as well as the trailer. The Custer Trailer Connector Adapter # ADP7R-7B that you found is designed to adapt a vehicle with a 7-way round pin connector to allow a trailer with a 7-way blade connection to be towed.

  • Recommended Front Camper Tie Downs and Electrical for Lance Camper in 2021 Ford F-350
    We do have the parts you're seeking for your 2021 Ford F-350. If you wanted a stake pocket tie down, the Brophy Stake Pocket Mounted Camper Tie Downs - Bed Mount - Black Powder Coated Steel - Qty 4 # TDSF are a universal solution that would work well; the only draw back to these is that they are permanently installed and do require drilling to install.
