Had to replace old connection that was worn out not working correctly. Fit perfectly. Thanks for your help !!!

The way the connector comes apart & goes back together is very sensible. The terminal connections can accommodate large wires - up to 12 gauge on all except for 1 that can go up to 10 gauge as far as I can remember. They could possibly handle larger but I didn't check since I didn't need the wires that large. They're labeled for standard 7-way trailer wire colors, which is useful for most people but I couldn't go by it. Mine was a custom application. If a spring strain relief came with it that would be awesome but I wouldn't expect it for the price I paid. Hope that info helps.

I searched locally for a 7-pin trailer plug without finding any round-pin styles only flat blade. I searched online and found this plug. This plug is very well made, easy to connect wires to and fits the socket on my Kubota tractor. Also, it was in stock and shipped much faster than I expected, which I greatly appreciated.

I have a 1993 ford e150 with a factory I installed trailer connector round pin. I couldn't find a 7 to 4 match anywhere. Then I saw this pk11700 adapter and it worked great. Plus I have extra connectors now to add other lights. Great product thx

The cable end plug arrived on the exact estimated date I was given on the day of ordering. Wiring it is very simple. There is a screw for each terminal opening. Use a small phillips screwdriver to thread the screw out, insert the wire, and then tighten the screw. A retention clamp is an integral part of the plug. Again it is a simple matter of turning a screw to open it and tighten it back down again. The plug is well made and should last a long time. It is exactly the replacement part I was looking for. I will come back to etrailer.com when I need related items. I highly recommend.

Just reviewed the truck receiver half of this product - same deal. Nice heavy parts - little plastic. Nice big round brass contact pins; due to the fact that these parts are cast, there is little chance of water/dirt/condensation working into the wire contacts. Locks in tight with the receiver. All in all, a good purchase.

  • Parts Needed to Connect Gooseneck Trailer to Semi-Truck 7 Pole Round Plug
    You can use the Pollack # PK11700 to install on your gooseneck trailer and create a 7 way plug capable of fitting on the 7 pole round plug that is on a semi tractor trailer truck. For the wiring you can use the Deka Jacketed 7 Wire # DW04914-1 which is a jacketed 7 wire sold by the foot that will allow you to connect to your trailer's wiring and the plug. If you just want to go the adapter route, you can use the Pollack # PK12-724.

  • Recommended 7-Way to 4-Way Adapter for 2018 VW Atlas
    To convert the 7-Way on your 2018 VW Atlas to a 4-Way, I recommend using the Pollak Adapter # PK12716. This will plug right into the Pollak 7-Way on your vehicle and provide you with a 4-Way flat on the other end. It also features a nice tethered cap to protect the connector from debris and corrosion. I have attached a short video demonstration on this adapter that you can also check out.

In order to make the adapter you will need the Pollak Heavy-Duty, 7-Pole, Round Pin, Trailer Wiring Connector part # PK11700, the Roadmaster Brite-Lite Wiring Converter part # RM-732, and the Pollak Black Plastic, 7-Pole, RV Blade-Style Trailer...

It sounds like you just need an incandescent bulb to draw power, so I recommend using this cover which has the bulb.

  • Which Pin On a 2018 Ford F-150 Trailer Connector Is For Reverse Lights
    Yes, the center pin for the 7-way trailer connector on your 2018 Ford F-150 is for the reverse light circuit. If the vehicle is placed into reverse then the pin will become active and send power to the trailer. I have attached a selection of our backup lights for you below. I recommend the Hot-Line LED Trailer Backup Light Bar part # 328-003-6017W because its's easy to install and has LED bulbs. In order to run the power wire from this light to the trailer connector you can use part # DW07550-1.

    A 7-pole round to 6-pole adapter, the Hopkins Trailer Connector Adapter # HM47445 will not actually require any wires - including the brake wire - to be connected to the adapter. You simply plug one end to your vehicle's 7-round connector and then plug in your trailer-end 6-round to the adapter.

  • Adapter Recommendation for Going From 7-Way Round to 7-Way Blade
    We have two adapters to go from a 7-Way round pin on a tow vehicle to a 7-Way blade style on a trailer. You could use either # PK12-724 or # HM47425. Either would work well for you if your tractor has trailer wiring setup for combined turn signals where the blinkers and stoplights are on the same circuit. If they are separate then you would need to install a second 7-way blade as that would be the easiest way. For that you would need a 7-way like part # 37185 and a signal converter like...

  • How Many Volts Should I Get to the Trailers Brakes When Pressing the Brake Pedal
    You should get 12 volts coming from your brake controller if the controller is set on its highest setting. If your not, the first thing to do is to examine the trailer connector for any corrosion or debris and clean it if necessary. You'll also want to check the ground wires for the magnets and the brake circuit wire from the brake controller for any damage or pinches.

  • Should Blue Wire on Trailer Have Power
    The blue wire on a trailer is typically the output wire to the electric brake assemblies. If this is the case on your trailer then the wire should only have power when you are hooked up to the tow vehicle and are applying the brakes, either by pushing on the brake pedal or by using the manual override lever on the brake controller. Since trailer wiring colors aren't always consistent I do recommend verifying that this is the function of your blue wire. You can simply follow the wire...
