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,

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.



by:

Items were simply “thrown in the box” WITH the hitch which was not secured properly. Heavy hitch then bounced around on electrical connectors, destroying them. Components should have been fastened to the hitch as the hardware kit was with strong tape instead of just thrown into the box by somebody! Refund issued.



by:

Do you guys carry a great inventory of trailer accessories and parts do a great job getting them shipped out to us Thanks for all the good work happy memorial day to you



by:

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.



by:

Everything was great. I'm going to use this for a remote winch control. I recommend this site to everyone. Thanks

What sort of controller are you attaching it to? I need to find a new controller and trying to find one that I can attach this to.



by:

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.



by:

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.



by:

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.



by:

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



by:

Works very well. Exterior is rusting th ough.



by:

Installed this product since I was converting a car from dolly towing to flat towing and needed this connector to interface with existing harness installed on tow bars. Impressive quality!



by:

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.



by:

Works just as it should! Durable!

Order for wiring, round plug, and plug mounting bracket delivered very quickly and is exactly what I needed.

Have bought from etrailer.com in the past and always been well satisfied with their products and service.

Made of metal. Definitely hold up better than the plastic copies.

Would have been nice to get this product in Black Chrome to match my bumper



by:

Connector worked great on my boat trail er.



by:

This connector worked perfectly on my trailer. Very happy I found e-trailer and that they carried this hard to find product.

Wrong size. Hard to know what size when ordering online.

Meghan L was a great help and I got my project product real quick and that's working great thanks

Very satisfied. Would not hesitate
to order from you folks again. Thanx...

As I said on all the other parts, I like the selection, pricing but mostly the help I get online and face-to-face.

Same as the review for the female end. Well made and just what I needed. Outstanding product.

  • 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...

  • 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...

  • Installing 4-way Round Connector on Tow Vehicle
    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 # PTW2993 to test for the wire's 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 extension...

  • Recommended Base Plates and Flat Towing Equipment for 2005 Honda Pilot
    What it simply means is that some of the base plate kits will fit your 2005 Honda Pilot if it has a brushguard and others won't. Personally I recommend the Demco kit, # DM9517143, because it works with whether you have the brushguard or not. I also like the Demco kits because they pair with the Demco tow bars that have independent arms, include safety cables, and are made in the USA. The Commander II, # DM9511012, would work perfectly for you. For a lighting solution, I recommend the...

    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...

  • Missing Connectors for Blue Ox 7-Wire to 4-Wire Coiled Electrical Cord # BX88254
    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.

  • 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 cars 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...

    The wiring harness for your 1998 Ford Windstar is a plug and play harness, part # C55346. It plugs into your tail light assemblies. I have also included a link to the instructions for installing it on your vehicle. The 4 pole round connector you were looking at, part # PK11409, can be used instead of the standard flat connectors. The part you were looking at was the trailer end connector. The vehicle end is part # PK11410. You would cut off the flat connector of the wiring harness mentioned...

  • 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.

  • Mounting Bracket Options For 4-Way Trailer Connectors
    We do offer a couple of mounting solutions for 4-way flat connectors, but the style differs from the Draw-Tite Bracket, part # 18159. You can check out the part # HM48595. This is a fold-over box 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.

  • 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...

  • Distance Between Mounting Holes on the Pollak 4-Way Round Connector

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.

    We actually don't carry any flat tow wiring for your 2008 Honda Element that plugs directly into the vehicle's wiring. We used to but it's been discontinued. What is in the instructions for the base plates is just the connector that would be at the front of the vehicle and for that you can use # DM9523004.

  • 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.

    We do not have an adapter in that exact configuration for you, but we do have the parts to make your own adapter. You could use 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.

  • 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.

    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.
