Video Transcript for Bargman Wiring - Trailer Connectors - 50-87-009 Review

Today we're going to be taking a look at the Bargman Car End 7-Way Super Sealed Connector with 9 feet of cable. It's going to feature the solid brass terminals, and we're going to have the industrial strength glass filled thermo plastic housing, so it's a nice, strong, durable design. It's going to have the heavy duty stainless steel spring for the lid, allows for easy opening and closing of the unit. The spring's protected right up here, and that's not going to rust or corrode, so you're not going to have to worry about that. You can see it has that spring loaded design. On the inside or bottom of the lid, we're going to have a nice rubber gasket. That's going to create the lid's super seal which is going to keep the connection points protected from the elements.

Again, we're going to have 9 feet of wiring to work with. That's all going to be protected by a nice, thick wire casing. I also want to point out that here on the back of the connector, we have this rubber spring boot. This is going to protect that juncture, that connection point from the wiring or the casing to the connector. That really reduces the amount of strain placed on that connection, and that's just a really nice design. Completely seals up the unit so we don't have any exposed wires here at the connector for any type of dirt or moisture to get in and cause any corrosion.

That's a nice overall design of the unit. When it comes to getting this mounted, it is going to require a 2 inch diameter hole, and then we have 4 mount holes pre-drilled right here into the connector. Mounting hardware is not included, so that will need to be provided separately. The distance between these mount holes on center is going to be about an inch and 1/2. Distance going this direction on center is going to be about 2 and 1/4 inches. Now when it comes to the wiring, you can see that they all are color coded.

This harness is going to contain 2 gauge 10 wires, 1 gauge 12 wire, and 4 gauge 14 wires. The green wire, this is going to be for our running lights. That's 14 gauge. Red is for left, stop, and turn. That's 14 gauge. Yellow is for auxiliary.

That's 14 gauge. Brown is for right, stop, and turn, and that's 14 gauge. The white wire is a ground wire. That's a 10 gauge wire. Black is for battery charge. That's 10 gauge, and then blue is for the electric brakes, and that's going to be gauge 12. Now it's always a good idea when installing to go ahead and double check the wires by function and not just rely on the color coding. Even though that your color coding might be correct, again, we always recommend getting the tester and testing by function. Again, overall it's a nice design built for strength and durability, and it's going to measure 9 feet long. That's going to do it today's look at the Bargman Car End 7-Way Super Sealed Connector.

7-Way Super Sealed Connector w/9' Cable - Car End - 50-87-009

Average Customer Rating:  4.9 out of 5 stars   (19 Customer Reviews)

Prewired 7-way car end sealed connector with 9' of 7-way cable.


Perfect for adding a plug up on the bed of my flatbed!


very heavy duty! have not installed yet, but looks of good quality.


Decent price, well made, and prompt shipping. Still functioning perfectly!


My uhaul bargman connector bit the dust, wanted to replace it with a solid, heavy duty bargman plug. Arrived timely and well packaged, just what I have come to expect from etrailer.

Solid as a rock
alex s - 11/23/2017


I paid a little more for this product but it has a 9' lead with a factory sealed waterproof connection on the plug end. Wiring diagram on the cover tells you what the color of the wire is - no guessing required. I cut the cable to length with a cut off blade on a grinder. The extra wire comes in handy for making other connections. Seems like I'm always repairing trailer leads and connectors, so this is a problem solver.


I needed a cable to go from truck to trailer while working on the trailer but when the trailer was not connected to the truck and this works just fine.


I installed 2 of these on my trailer 1 year ago. Love the molded aspect of the plug. No issues and I would recommend this to anyone


Very good quality wiring, has served us well.


Worked great for boat hookup to back of 5th wheel.


Excellent product. fits very well.


Quality product And a timely delivery much appreciated


A good product!


Works as intended

Cody - 04/11/2020


As normal with etrailer, quick delivery and exactly what I needed. etrailer is my go to place when I need something trailer related. Only site I found that had a ~10 foot 7-way pigtail. This time it is not even for a trailer. I am hooking up my field and brush mower remote control to my Kawasaki Mule so I can quickly connect and disconnect it.


Just what I needed. Great product and great price.



Good just what needed cable was long ,



As expected.


Ask the Experts about this Bargman Trailer Wiring

  • Are There Different 7-Way Trailer Wiring Connectors on RVs
    Basically all 7-ways you see either for sale from us (or anywhere), or on the road are all made to the same size. This makes picking out replacement really easy as you know the sizing is correct and you don't have to check to make sure you have the right size or version of the 7-way. So the # 50-87-009 that you referenced would be a standard 7-way blade socket which would work well for you if that's what you are looking for.

  • Which Style of 7-Way Wiring Does Hopkins 7-Way # 50-87-009 Use
    If you check out the picture of the lid of the 7-way part # 50-87-009 that you referenced you can see that it uses the RV standard style of wire colors and not the traditional standard seen on utility trailers. I also attached a diagram that matches this as well.

  • Solution for Needing Wire Colors Labeled of 7-Way Trailer Wiring Kit
    I really wish we did, but I checked the wiring harnesses of the 7-way plug and leads we offer like the part # 50-87-009 and none of them do. Best option would be to find someone who could identify them so that you could label them as needed.

  • Standard And traditional Wiring Configurations For 7-Way Trailer Connectors
    There are traditional and standard wiring configurations and that can be frustrating when working with electrical connectors. We try to always remind customers to check wiring for function and not to rely on the color of the wires for that reason. The standard connectors are typically wired for fifth wheel and travel trailers and the traditional is typically used for utility and cargo trailers. I have attached a couple drawings that show the wiring configurations for standard, traditional,...

  • Wiring 5th Wheel Trailer to Tow Second Trailer with Brakes
    When wiring up your 5th wheel trailer so that it can connect to the lights and brakes of your second UTV trailer it is just a matter of completing the circuits between the two. To add a 7-Way connector to the 5th wheel you can use the Bargman 7-Way # 50-87-009. The blue brake output wire on the 7-Way needs to be spliced into the brake output wire that is coming from the brake controller in your tow vehicle. You will then just connect the rest of the wires to the appropriate signal light...

  • 7-Way Recommendation for Installing on Older Horse Trailer
    I have a great solution for you, but the part # 50-87-009 is the vehicle side trailer connector. It is a 7-way like you need though so you are on the right track. For your trailer you would want the part # H20036 which would go well with the part # 50-87-009 if you installed it on your tow vehicle. I attached a help article that has trailer wiring diagrams as well.

  • Can the Curt 7-Way Extension be Used with a PowerMax Converter to Power Trailer
    Instead of using the Curt Extension # C56080 I recommend using the Bargman # 50-87-009. This comes with an extra 2' of wiring and it already has the female end disconnected so less work on your part! Then the correct wires that you need are the black and white wires. Black is for power and white is for ground. Be sure to follow the instructions for your PowerMax during the installation.

The blue (brake output), black (12 volt power) and white (gound) wires are 12 gauge. I am sure the boot on the back of the 7-Way Super Sealed Connector part # 50-87-009 could be trimmed down but you would be opening yourself...

  • Solution for Going From Euro Trailer Wiring Connector to RV 7-Way
    The best solution I can offer you is to cut the Euro 7-way off of your vehicle and wire a new 7-way to your vehicle by function. The best way to do that is to use a circuit tester like our # PTW2993 to determine the functions of the wires by having a buddy apply the different brake and tail light functions while you use the # 3808 to determine which wire does what and then wire it to the 7-way like the picture I attached. Once you do this you will be able to tow your boat trailer, but...

  • Is there an Adapter to Go From Semi Style 7-Way to RV Style 7-Way Trailer Connector
    Because the functions on a semi 7-Way connector are different than those in the RV industry a regular adapter would not work. Some of the circuits have to be combined so a converter is needed. It would actually be easier to just add an RV style 7-Way on the semi rather than making an adapter as described in the question you referenced. If your semi has combined brake lights and turn signals on the same circuits then you would just need a vehicle side 7-Way such as # 50-87-009 and wire...

  • Replacement 7-Way Trailer Connectors For Bumper and Gooseneck Connections With Limited Space
    The 7-Way Super Sealed Connector w/9' Cable # 50-87-009 will have a little flex as there is a spring inside the boot that allows for some flex but is also designed to retain the wiring from any harsh bends that could damage the wiring. I have a recommendation for using the Replacement Custom Multi-Tow 7-Way and 4-Way Trailer Connector # 30955 as the connection for the bumper plug and the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # 41157 for the gooseneck plug.

    The 7-Way Super Sealed Connector w/9' Cable # 50-87-009 is only rated to be used with 12 volt systems. A Pollak Heavy-Duty, 7-Pole, Round Pin Trailer Wiring Socket # PK11720 is rated for 6-28 volt applications and will allow you to use a 7 round pin style trailer connection. You can use the Pollak Heavy-Duty, 7-Pole, Round Pin, Trailer Wiring Connector # PK11700 on the trailer end. I have added an image below to show you where the wiring goes for the 7-pin connectors.

  • How To Replace The Factory 7-Way Connector And Harness On A 2006 Ford F-250
    I do have an option available for you to consider however, the factory pigtail harness you are looking for is not available from the main aftermarket manufacturers. The option we can offer you is a hardwire harness like the 7-Way Super Sealed Connector part # 50-87-009. This harness will be hardwired into your 2006 Ford F-250's factory wiring harness. As they are not vehicle specific, you will need to test each wire to ensure they are attached to the correct wire. You can do this by using...

Most passenger vehicles come with a pre-installed 4 way flat connection that require a 7 way to 4 way kit, such as Curt Trailer Connector Adapter # C57672. Or if you already have the 7 way wires at the back of your vehicle then you can use 7-Way Super Sealed Connector w/9' Cable Car End # 50-87-009 to wire in the 7 way connector. If you need...

  • Brake Controller Recommendation for 1983 Jeep CJ7
    You will need to start with a 4-way (if you do not have one). For that you would want the # 18252. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. For a brake controller I would recommend the Brake EVN # TK63VR. This is one of our best selling brake controllers...

  • Vehicle Side 7-Way Pigtail 10 To 12 Feet Long
    The longest 7-way sealed connector for the car end we currently have is the Bargman # 50-87-009 which is a 9 foot long pigtail. For a longer wire, you can use the Pollak Black Plastic, 7-Pole, RV Blade-Style Trailer Socket - Vehicle End # PK12-707E along with the Deka Wire - Jacketed 7-Wire - per Foot # DW04914-1. This will allow you to customize the length needed.

  • Recommended Parts To Adapt 7-Way Vehicle Connector To 6-Way Trailer Connector.

Once you have the 4-way, you can install either a 6-way or a 7-way. Factory tow packages come with a 7-way, but you can install a 6-way and be set for your camper.
