I was super impressed with the service from etrailer.com! The product was just what I wanted, price was great, and I received it in just a few days.

Exactly what I needed. Etrailer always comes through



by:

I was very pleased with this connector. It is robust and of high quality for its cost. I'd highly recommend it.



by:

Packing,shipping&Item PERFECT!!! etrailer your the bomb !!!

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 am very pleased with the product. It is working great on my Kubota tractor.



by:

If you have any agricultural equipment, this is the easiest way to adapt the normal automotive style connectors to your vehicles and equipment. Great product, and as usual, ETrailer.com has the best price and least expensive way of shipping it to you.

Still great,



by:

Product was as expected.



by:

Plug is great it comes w/o the wire releaf support at the tail end of plug.



by:

The plugs did what they were supposed to do, and the customer service was excellent.



by:

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.



by:

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



by:

the connector is "as advertised" (which is refreshing) it needs some sort of protective cover of the wires as they enter the plug, but maybe it is available and i didn't see to order it. I would buy it again.



by:

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.



by:

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.



by:

Haven't wired up the connector yet. Would have been nice if the standard wiring diagram used through out the USA would have been included. Then the trailer would be wired correctly to any vehicle that was using it. Mine didn't have the trailer brake or back up lite shown.




by:

For me, and probably you, etrailer.com is a great place to shop/buy quality products. They give great follow up after ordering and fast shipping @ a fair price. I believe their service & pricing is unbeatable. I do shop for bargains & etrailer is @ the top of my list.



by:

i did not realize there are TWO different sizes of 7 pin round connectors ?? apparently i have the smaller one and the one i got was way to BIG .....



by:

It is very refreshing in this age of Internet shopping to find a site that provides good product information, competitive pricing and great customer before and after the purchase. Product was exactly what the product info on the site stated. Appreciate the good service and will definitely use etrailer.com for future needs.

Thanks.



by:

Worked perfectly to replace an electrical plug one of our drivers ripped off by accident. Was able to save the whole harness for $10 with this!



by:

I have used this connector on an equipment trailer for the last year with no issues. It has worked flawlessly. It was a good decision to go with this item.



by:

Plug appears to be of very good quality and is as represented. We are using this plug to make an adapter harness to plug our RV into a semi tractor.



by:

Solid product. Can't wait to get it installed. Going to use it as a auxiliary power device for my tractor hardtop. Lights and wiper hookups.



by:

Product arrived timely and in excellent condition. It came with SAE J560 instructions that were helpful. Wiring the connector was easy.



by:

I got exactly what I expected. Great customer service & follow through.

  • Recommended Parts Needed to Flat Tow a 2012 GMC Sierra Behind a Semi
    You will need an entire flat tow setup on your 2012 GMC Sierra in order to do this the right way. Here are the parts I recommend using for this: - Blue Ox Allure Non-Binding Tow Bar # BX7460P (comes with safety cables) - Blue Ox Base Plate Kit # BX1674 for 1500 or # BX1694 for 2500/3500 - Hopkins Custom Tail Light Wiring Kit # HM56101 - Flexo-Coil Kit # RM-146-7 - Pollak Heavy-Duty, 7-Pole, Round Pin Connector # PK11700 - Brake Buddy Classic 3 Portable Supplemental Braking System...

    As your 7-Way pin connector uses separate turn signals and brake light wiring you will need the to create a custom harness to be able to have everything function properly including the electric brakes. First you will start with the Pollak Heavy-Duty, 7-Pole, Round Pin, Trailer Wiring Connector # PK11700 to connect to your vehicle.

  • Will the 7-Way Round Pin to 4-Flat Adapter Work On a Semi
    I do have an option for you but the 7-Way Round Pin to 4-Flat Adapter part # 47405 won't work on semi's as there is no converter integrated into the adapter. The lights on a semi are separate and the lights on a trailer are combined so a converter is required. Therefore, you will have to make your own adapter using the Hopkins Tail Light Converter part # HM48847, 7-Round Connector part # PK11700, and Hopkins Wiring Harness with 4-Pole Flat Trailer Connector part # HM48035.

  • Availability of 7-Pole Round to 6-Pole Coiled Wiring Harness for RV
    It sounds like you're looking for tow bar wiring like the # RM-146-7 but with a 7-pole round connector on one end. We don't have an option that comes this way but you can put one together yourself with the right parts. You need the # RM-1046-R for the wiring. Then for the 6-pole you need the # RM-910030-8 and for the 7-pole on the other end the # PK11700.

    We do offer quite a few types of trailer wiring adapters/extensions that can be seen by clicking on the linked page. Just select the vehicle end you need (we offer both 7-way round and 7-way flat blade style connectors) and then the other end you need. For a 7-way round pin to a 7-way blade you can use # HM47425. Or for a 7-way blade to a 7-way round use part # 47595 or # F77R. These products feature one male and one female connector. We do not have a male 7-way round pin to female 7-way...

  • Troubleshooting 7-Way to Semi 7-Way Adapter Stoplights Not Working
    The problem you most likely are experiencing is due to fact that semi trucks have the turn signals and stoplight circuit on separate circuits/wires. Standard trailer wiring has the stoplight and turn signal circuits on the same wire. So in your situation you would need to wire in the Hopkins Tail Light Converter part # HM48847 on just the stoplight and turn signal circuits and you'll be good. A brake controller would not affect the stoplight circuit at all.

  • Troubleshooting Trailer Brakes Not Working After Breakaway Pin Pulled
    If the trailer brakes aren't working anymore after the breakaway pin was pulled it's possible that the brake controller on your truck was damaged during the incident. A lot of older brake controllers didn't have the circuit protection built-in to them to prevent backfeed from the trailer when something like this happens. To test the controller you will want to sever the blue brake output wire a few inches from the back of the unit. Test the blue wire with a circuit tester or multimeter,...

  • How To Tow a Gooseneck Trailer with Brakes Using a Semi Tractor
    In order to haul your gooseneck trailer with a fleet of semi-tractors you will need to make your own adapter harness which will then make for a plug and play connection but they don't make anything pre-assembled for this out of the box to my knowledge. 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...

  • Recommendedations To Change 4-Way Connector On Trailer To 7-Way Connector
    It sounds like you want a permanent change from the 4-way connector to a 7-way connector on your trailer. We carry trailer-end 7-way connectors and the one I recommend is the Pollak Metal 7-Pole Connector, part # PK12702. This is a blade-style connector. If you have a round-pin connector on your vehicle I recommend part # PK11700. This would require cutting the 4-way connector off your trailer. You would need to test the wires on the trailer using a 12V power source to see what each...

  • Which Pins on a Heavy Duty 7-Way Round Trailer Connector are Power and Ground
    I attached a diagram that shows a heavy duty 7-way pin out like the part # PK11700 that you referenced (diagrams on right of pic). The 12 volt circuit is normally in the center pin, and the ground is normally the top one. The colors aren't always standard on applications so best option is to determine function by pin location instead. Power MIGHT be black and ground most likely is white though.

  • Troubleshooting Trailer Wiring Where All the Pins of 7-Way Have Voltage on Them
    If all of the pins on your 7-way trailer wiring connector have voltage on that would indicate that you have a short most likely between the 12 volt accessory circuit and the other circuits. I'd recommend going over the wiring behind the 7-way looking for any cut or exposed wire and fix as needed. I attached a help article on troubleshooting trailer wiring for you to check out as well.

  • Troubleshooting Trailer Brake Controller That Outputs 4 Volts with No Brake and No Manual Override
    If you are testing at your vehicle's 7-way and are detecting just over 4 volts on the brake circuit when neither the brake pedal nor manual override are engaged then you may have a bad controller, or you could have a short in your trailer socket that is allowing the 12V power circuit to bleed over to the brake circuit. Carefully inspect the 7-way (inside and out) for signs of corrosive build-up that could be bridging circuits. If you are testing the controller's output on the blue wire...

  • 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.

  • Wiring # PK11700 Pollak 7-Way Trailer Connector
    The white wire is typically ground, you can confirm this by checking to see if it connects directly to the trailer frame. Your yellow wire is usually the left turn and brake lamp, green is right turn and brake light. The yellow/black and green/black are running lights, with the green/black running down the passenger side and the yellow/black running down the drivers side. You can confirm this by using a car battery, grounding the white wire to the negative terminal, and applying 12-volts...

What you will need to do is create your own by wiring a 7-round trailer end connector, # PK11700, and 4-round vehicle end connector, # RM-910030-1. I recommend going with the 14 gauge, Deka Jacketed 4-Wire, # DW04923-1, which is available per foot so you can get the amount you need. If you have an RV-style connector (which is often referred to as a 7-round), then the part you would be looking for is the Hopkins...

    We don't have a wiring diagram that details what your trailer connector wiring would be based on color but I can give you an easy way to determine this. You will need a circuit tester like part # PTW2993 and you will want to test each of the wires for voltage when the different turn signals are applied. You might use masking tape to label each wire to make this easier. Once you have all of the wires sorted out you will then want to wire them to your new connector using the diagram I attached...

  • How to Determine Wire Functions on a Tandem Axle Dump Trailer
    Trailers in the US have combined turn signals and brake lights on the same circuit. So it is likely that the yellow wire is left turn/brake lights, green is right turn/brake lights and brown is running lights. That leaves black and red. One of them is the ground, likely black, and the other is for another function, possibly 12 volt power or for an electric reverse lockout if the trailer has hydraulic brakes. The easiest way to determine wire function would be to run power using a separate...

  • Testing for Proper Voltage on the Brake Output Circuit
    There are many things that can affect the voltage on the brake output wire from your brake controller to your trailer brakes such as the power setting on your brake controller, how you are testing the wire and if you are testing it with the brakes or manual override activated. Using a multimeter to test the voltage on the brake output wire at your trailer connector will not always give the proper reading because it does not provide a load on the circuit like brake magnets from a trailer...

  • Troubleshooting Trailer Wiring that Stops Working With Headlights on
    Try improving the connection of the main ground wire of the trailer wiring harness. Make sure it is attached to a clean metal surface. Or you can run all of the trailer wires back to the main ground. This is actually the ideal solution. But you can also check the current grounds for the lights to make sure they are making a solid connection to a clean metal surface. What you described is the classic insufficient ground scenario so finding a way to improve the grounds will fix the problem.

  • What is the Function of the Red Wire on a Pollak 7-Way Trailer Connector/Wiring Harness
    On a Pollak 7-Way trailer connector/wiring harness the red wire is for left turn signal and brake light functions. On many aftermarket wiring harnesses you usually see a yellow wire for left turn and brake lights at the trailer connector. But on a Pollak 7-Way the red wire takes that function. I have included a link to our help article on trailer wiring which includes diagrams of the front and back of both vehicle and trailer side connectors.
