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. 790895

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. 278555

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. 210881

Ask the Experts about this Pollak Wiring

  • Recommended 4-Way Connection Between Towed Vehicle and Motorhome
    The only real advantage of the 4 round over the 4 flat trailer connector is the clean look of the connection point and the protection from elements when not in use. For instance the Pollak Heavy-Duty, 4-Pole, Round Pin Socket, Concealed Terminals - Chrome - Vehicle End # PK11410 has a clean finished look on the front of a towed vehicle and will protect the connection from dirt and debris with the spring loaded cover. Many people like the connection between the motorhome using a harness...

  • 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.

  • 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,...

  • 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.

  • 4-Way Round Chrome Car End for a 2003 Jeep Wrangler To Tow Behind Motor Home
    To install towing lights on your 2003 Jeep Wrangler you have two options. One way is to use a taillight isolating diode system, RM-154, to wire the motor home lighting system into the car's with diodes protecting both from damage. The second is to use a separate set of bulbs in the rear taillights, RM-155, that are run only from the motor home and do not interact with the vehicle wiring. This option requires enough space in the towed vehicles taillights to mount the extra bulb, but it eliminates...

  • 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...

  • 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.

  • 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...

    The Tekonsha T-One # 118786 that you referenced is for activating the light functions on a trailer when towing with your 2018 Jeep JL Wrangler Unlimited. It sounds like you are needing some wiring to flat tow your Jeep and for that you need some different parts. If you use the Hy-Power Diode Wiring Kit # RM-152 along with the Hopkins Mounting Bracket # HM48605 and the Pollak Heavy-Duty, 4-Pole, Round Pin Socket # PK11410 then you will essentially have the Flexo-Coil Wiring Kit # RM-15267...

  • Availability of Adapter to Go from 4-Pole Round on Trailer to 4-Pole Flat on Vehicle
    I do have a couple options for you, but there isn't an adapter to go from a male (trailer end) 4-pole round to a female (vehicle) 4-pole flat or even a 7-way. So, you could either make your own adapter using part # PK11410 and # HM38138, if you do not want to modify the harness on your magnetic trailer lights, or you could simply replace the 4-pin round connector on them with part # HMC20031, which is going to be the most cost effective.

  • 7 Wire to 4 Wire Round Adapter Needed
    I have attached a picture for you. If you need connectors like those in the picture then you can use the Hopkins Endurance Flex-Coil Trailer Connector Adapter with Nite-Glow, # HM47043. This adapter is designed for use when flat towing, 7-wire blade-style vehicle end connector and 4-wire round towed vehicle connector. If you have a different style of connector, please send me a picture and I will be happy to find a product that will work for you.

  • Is there an Adapter that will Convert a 4-way Round Trailer Connector to a 4-way Flat Vehicle End
    I have checked the adapters that we currently carry, and we do not have an adapter that will fit the configuration that you specified. You could create your own adapter, and it would be composed of the Pollack # PK11410 and the Hopkins Endurance 4-way Flat Trailer connector # HM48110. You would just wire the Hopkins 4-way flat to the Pollack 4-way round connection point. This will create an adapter that will connect the 4-way round on your 1972 trailer with a 4-way flat vehicle connection...

  • How to Make a 6-Way Round to 4-Way Round Trailer Connector Adapter
    There isn't a 6-Way round to 4-Way round adapter that we carry but we have the parts to make one. First, a 6-Way is not very common, make sure it is a 6-Way, like # PK11609, and not a 7-Way blade style like # PK11893. If it is a 6-Way round then to make an adapter you would first need a 6-Way round trailer side connector, # PK11604. Then you would need a 4-Way round vehicle end connector, # PK11410. Then all you would need is about 1 foot of bonded 4-wire, # 16-4B-1. You would just...

  • Mounting Bracket Options For 4-Way Trailer Connectors
    We do offer a couple of mounting boxes for 4-way flat connectors, but the style differs from the Draw-Tite Bracket, part # 18156. You can check out part # RP74641 and part # HM48755. These are designed to protect your 4-way flat connector. I have attached links to our product pages that list the mounting brackets we have for 4-way round and 4-way flat trailer connectors.

  • 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.

    If the 4-way on your RV is a round socket, you will need to wire the Roadmaster 4-Wire Straight Cord Kit # RM-98164 to match the wiring on your RV function for function. Since RVs do not commonly come with 4-way round connectors, it is hard to say how the 4-way is wired. You can use a circuit tester like # 40376 to test for the wires functions. If the 4-way on the RV is not round, I recommend using the Hopkins Endurance Flex-Coil Trailer Connector Adapter # HM47043. This wiring extenstion...

    I'm going to assume that you have a Blue Ox coiled electrical cord, like part # BX88254, which has a 7-way for your motorhome. 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.

    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.
