I am ‘five star satisfied’ with the products and service I have received from etrailer. Parts are high quality, unlike merchandise I I’ve purchased elsewhere. The customer service is high quality, again unlike others I’ve dealt with. Specifically, I have dealt with Danielle twice and she was fantastic. Pleasant, courteous, knowledgeable and professional. etrailer is lucky to have her on their team.

Product arrived on time and as described. I used this for setting up our 2014 Wrangler Unlimited Sahara for a flat tow. Mounting hole spacing @ 2" o/c didn't match our Blue Ox 1126 draw bar so I fabricated my own intermediate bracket, polished it to aircraft tooling standards, then lacquered it before final assembly. I think the finished product came out nice.

Just over one year and its still working out great! Ive fabricated several intermediate brackets much like my own for neighbors.

Wiring harness and flat tow bracket to be able to tow our new Wrangler behind our motorhome. Product arrived on time and everyone was most pleasent to deal with. had the bracket installed by the dealre we bought the Wrangler from as part of that deal and then did the wiring ourselves. Pretty weasy thanks to the excellent video provided by etrailer and it took us rookies about 3 hours to complete. we are very happy with the service and product. Thanks to all. Regards,

I was disappointed when I opened the package. The connections are to be used together. These connections can never be used as 1 unit on a trailer and Vehicle. The pin , and Holes on the female, and male plugs are different.

Using this 4 way connector as a 2 way to add 12 volt power to my tow vehicle from my RV.

Just what I ordered and expected. My former, local source discontinued carrying the outlet which I needed for my vehicles to connect to the lighting on my trailers. Was good to find a new, reasonably priced source so I did not have to change the wiring on all my older vehicles and trailers.

Well made and sturdy construction. It would have helped if the mounting hole spacing was listed in the specs so I could have pre-drilled the panel on my trailer.

Product was good quality. Some of these receptacles from other suppliers are made of plastic. You don't find out until you get it home and open the package. I wasn't sure what I was going to get.....but was happy that it is metal and not plastic. I should have known that Etrailer would sell a quality product and not try to pass off junk like some of the others. My advise: always buy trailer parts from Etrailer. Don't take chances with someone else.

Ask the Experts about this Pollak Trailer Wiring



  • Distance Between Mounting Holes on the Pollak 4-Way Round Connector
    I grabbed a Pollak Heavy-Duty, 4-Pole, Round Pin Trailer Wiring Socket, # PK11404, from our warehouse to measure and found the distance between the mounting holes on center is 1-3/4 inches. If you check out the picture I attached you will see that you would have to come up with a shackle type adapter to allow this connector to be used on your base plate.

  • Diameter of Pollak Heavy-Duty 4-Pole Round Pin Trailer Wiring Connector Part # PK11409
    The Pollak Heavy-Duty 4-Pole Round Pin Trailer Wiring Connector part # PK11409 is 13/16" diameter on the end where it would plug into the vehicle side connector. If I were you, I would order both this and the Pollak Heavy-Duty 4-Pole Round Pin Socket part # PK11410 to make sure I have an exact match as these two connectors are designed for one another. If the trailer side connector that you have works with the above which it should as they have the same 13/16" diameter then you can return...

  • Lights Not Working Properly on Camper With a 4-Way Round When Using 7-Way to 4-Way Round Adapter
    It sounds like the 4-Way round connector on your camper is not wired correctly to match the 4-Way round on your 7-Way to 4-Way round adapter. Usually on a 4-Way round the top two pins are for the right turn and brake signal and left turn and brake signal, and the bottom two pins are for taillights and ground. If you have the coiled cord adapter like the Hopkins Flex-Coil Trailer Connector Adapter 7-Way to 4-Way Round, part # HM47043, I would recommend to plug your adapter into your tow...

  • How to Wire a 4-Way Round Trailer Wiring Connector
    There is no standard for wiring the 4-way round connector so you will have to use a circuit tester, part # 40376 if you need one, to test the wires and wire the connector according to the wiring of your existing connector. I have posted links to the parts mentioned above and our wiring help page below.

  • Diagram for 7-Way and 4-Way Trailer Wiring Connectors
    There is not an industry standard layout for wiring the 4-Way round pin connector, but there is a layout that is most accepted. If you you are looking at the front side of the 4-Way round trailer side plug, the top left prong would be used for right hand turn signal and brake function, the top right pin would be the left side turn signal and brake light function, while the bottom left would be used for the tail light function. The last pin, on the bottom right would be used for the ground...

  • Is the 4-way flat to 4-way Round # 47465 Compatible with with 4-Pole # PK11404 and # PK11410
    I went and pulled the Adapter part # 47465, Pollak Heavy-Duty, 4-Pole, Round Pin Trailer Wiring Socket # PK11404 and Pollak Heavy-Duty, 4-Pole, Round Pin Socket # PK11410 to see if they were all compatible and I found that they were. The round 4-way of the # 47465 is compatible with both the # PK11404 and the # PK11410. Check out the video I attached where I show this.

  • 4-Way Round Chrome Car End Wiring Details
    There is not an industry standard wiring diagram for the 4-Way Round Car End, part # PK11410. You will need to use a circuit tester, part # 40376, to check which pins have which functions on your trailer, and then attach the corresponding wires to their respective pins on the vehicle connector. If you are towing a vehicle behind a motor home the connections are usually as follows. The top left connection inside the vehicle end, with the cover raised, is the yellow left turn/brake connector,...

  • Troubleshooting Both Trailer Blinkers that Activate When One is Applied
    If your trailer was able to connect to the part # PK11410 the problem is not that your vehicle needs a different style connector. The problem would be that there is an issue with your wiring. It sounds like your blinker circuits have shorted out to each other and when you turn on either blinker they both illuminate. First thing you should do at this point is test the 6-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight...

  • What are the Functions of the Pins on Pollak Heavy-Duty, 4-Pole, Round Pin Socket PK11410
    The Bulb and Socket kits bypass the toad vehicle wiring completely so the 4-Way, # PK11410, just has to be wired to match what is plugged into the front of it. Usually the configuration is as follows: If looking at the back of # PK11410 where the wires attach top left is right turn signal/brake lights, bottom left is running lights, bottom right is ground, and top right is left turn signal/brake lights.

  • Availability of 4-Way Flat to 4-Way Round Adapter
    I do have a solution for you, however we do not currently have an adapter available that has a 4-way flat on one end and a 4-way round male connector at the other end. I recommend using the Pollack Heavy-Duty 4-Pole Round Pin Socket # PK11410 along with the Hopkins Endurance 4-Way Flat Trailer Connector # HM48110 for your application. You can simply wire the Hopkins 4-Way flat to the Pollack 4-Way round connection to get exactly what you are needing.

  • Replacement 7-Way Recommendation for Trailer with 2 Round 4-Ways
    It's highly unusual for a trailer like yours to have two round 4-ways like what is in the picture you sent in. It's possible they would match the # PK11410 which is a female 4-way socket but I'd have no way of knowing how yours are wired since they are not standard. Best option I would have would be for you to cut off the 4-ways and wire them to a 7-way plug like part # H20043. To identify the wires of the connector you'd need to use a 12 volt jumper wire from a vehicle battery's positive...

  • What Is the Size of the Socket On the Hopkins Heavy-Duty Trailer Coiled Extension HM47045
    The Hopkins Heavy-Duty Trailer Coiled Extension part # HM47045 has two standard 4-round trailer connector sockets on each end which are both 13/16" diameter. This is more than likely what you have now as I am not aware of there being multiple different diameters for a standard 4-round trailer connector socket. That said, I can confirm for a fact the Pollak Heavy-Duty 4-Pole Round Pin Socket part # PK11410 will fit this extension harness.

  • Compatible 4-Way Round Trailer Connector for Hopkins Flex-Coil Trailer Connector Adapter, # HM47043
    No, you will want to use the Hopkins Endurance Flex-Coil Trailer Connector Adapter, # HM47043, with 4-Way # PK11410. It is not compatible with # PK11404. Regarding the wiring configuration there is really no standard way of wiring a 4-Way round connector. But if you are looking at the front of connector PK11410 the bottom left is ground, top left is left turn/brake lights, top right for right turn/brake lights, and bottom right is running lights like in the video I have linked.

    The wiring harness for your 1998 Ford Windstar is a plug and play harness, part # C55346. It plugs into your tail light assemblies.

  • Availability of Adapter for a 7-Way RV Trailer Connector to 4-Way Round Connector on a Tow Dolly
    We have 1 7-Way blade style to 4-Way round adapter. It is # HM47043. The coiled adapter can stretch to 8 feet long and it will glow when connected so you can see it easily in the dark. The 4-Way end would plug into a vehicle side 4-Way since this item is used for flat towing a vehicle. If your tow dolly 4-Way plugs into a a vehicle socket as well you would have to remove the 4-Way on the tow dolly and wire in connector # PK11410 in its place.

To replace the connector on the front of the towed vehicle you can use part # PK11410, and for the connectors on the cord, # PK11409 for 4-way and # PK12706 for 7-way. I have included a picture for you which shows each style of connector and part number.

  • Solution for Connecting 6-Way Round on Towed Jeep to 4-Way Round on RV
    For your particular setup there isn't a single adapter available so your best option is going to be to just make your own using the Roadmaster 4-Wire Flexo-Coil Cord # RM-1064-B. This expands to over 8 feet to reach the distance between the RV and your Jeep and you can splice a 4-Round # PK11410 at one end and a 6-Round # PK11604 at the other to create the harness you need. This will give you a nice clean setup where you don't have to worry about connecting a bunch of adapter each time...

  • 7-Way Blade To 4-Pole Round Female Adapter
    The configuration you are looking for is pretty rare so an adapter like what you are wanting isn't available. So your best option would be to make one starting with the part # RM-1064-B which is coiled 4-way wiring that you could attach the connectors you are wanting on either side. For a female round socket on one end you could use the part # PK11410 and then for a 7-way plug part # PK12706.

  • 4-Way Round Trailer Connector for 12 Volt Trailer Wiring Circuit
    For a 4-way round plug we have the part # PK11402 and then for a matching socket part # PK11410 which would work great if you wanted to use it for connecting to a 12 volt battery. Since this is an alternative use for this type of connector you really don't have to use any specific wire of either connector and would have freedom to pick which ever. For carrying a higher amperage you could use the 10 gauge wire part # 10-1-1 which we offer by the foot.
