7-Way Molded Connector w/ 10' Cable - Trailer End - 50-67-005

Average Customer Rating:  4.7 out of 5 stars   (76 Customer Reviews)


Old plug was cracked and my truck periodically reported faults and disconnects. This one is really well built with the plug molded onto the cable. Wires are all correct gauges (10 thru 14) and very flexible. Excellent product.


Used this to replace a damaged connector on a horse trailer. Worked really well, and was easy to connect to the existing wires. No issues after everything was soldered and marine wrapped.


Pictures not included with review of the PK52248 junction box.


This product was exactly what I needed and the installation was easy even for a person with no real electrical experience.


I purchased a renovated 1965 Friendship Vacationaire and I had problems with the wiring not working properly. The electric brakes said that I had a short circuit so I decided to replace the wiring harness from the trailer back. Now the problems are gone and I'm once again a happy camper.


Can't tell you anything about the product yet but if its anything like the other products I have gotten from etrailer they will be fantastic. I can say that if I need trailer parts I will always get them from, your products are great and you guys always ship freaky fast! Amazon could learn a thing or two from your shipping department. I also lie the way you are in constant communication with your customers regarding order status, just amazing!! Tanks for the outstanding job.

CAUTION: USE AN OHM METER AND CHECK FOR PROPER WIRE COLOR TO CONNECTOR PINS BEFORE YOU INSTALL THIS! Some yahoo mixed up the wire connections inside the molded connector. Red is where yellow should be. Yellow is where red should be.Green is where brown should be. Brown is where green should be. This is not a huge problem because these 4 wires are all 14awg. Just make sure you check for proper wire color to pin orientation!

This 7 way trailer connector was an exact replacement for the original on my RV that needed replacing. Shipped fast and received exactly what I needed.


Great product.... reason for changing installed a battery in my cargo trailer which would charge of my truck. This would eliminate leaving my trailer plugged into my truck draining the battery when my interior lights were on in the trailer for periods of a time. It was easier to cut and splice in new harness. Make sure you get the correct length. Also went to a seven pin direct connect to truck rather than using adapter from seven to four pin to match trailer plug..... again great product.


Exactly what I was looking for. My old cable was only 8' long and would barely reach using it with an equalizer hitch on my Airstream. This was the original brand, just longer.

Still works great after a year. Nice to have the extra length when using an equalizing hitch.
Steve S - 09/15/2016


Excellent and well made part.

replaced the electrical tape wrapped, spliced old connection from my trailer with this high quality part.

Still going strong, could not be happier.

I've purchased at least 12 of these harnesses for the many trailers I and my sons have. This is a great product

Everything is great. The wire harnesses and components all are in good condition.
Steve S - 02/05/2018


The Bargman molded 7 way trailer harness has been used a lot as the trailer is used frequently. The harness has held up well during the year we have had it and the elements have not affected it.


The product had to be back order; it actually arrived several days sooner then the original estimated delivery date. George J. kept me well informed with status e-mails which I appreciated. I was very pleased with the quality of the 7 way connector cable. Every bit the same quality as what came original on our travel trailer. An outstanding and helpful bonus provided are your how to DIY videos. You guys got customer service well in hand!
Thank You....


The product was shipped quickly, although I had a few delays in getting it all hooked up. I am using this pigtail to connect from my 2019 Ram 3500 to a slide in truck camper using a 7 pin connector. It was helpful to have the color coding wire table to assist me.


We would like to thank James for the help on the cord we needed for our fifth wheel, and the extra help getting it here very fast. We have ordered several items from etrailer and they are always very helpful and get our orders out fast and always have excellent choices and prices. Thank you. Terri


I needed a longer boat trailer lighting pigtail to fit my new truck.
Went from a 8’ to 10’ Bargman 7
Fast service and turn around.
I noticed that after I purchased my product, the price went down.
I contacted customer service to get a price match.
They were more than happy to refund the difference because I asked.
I am always pleased when ordering from etrailer.


Great wiring, great insulation - seems to be well built. Bought this to rewire my CDN-M101 off road trailer and it worked perfectly. It has been one year and is holding up like new.


delivery was on time and the wiring harness was exactly as described

I can say that if I need trailer parts I will always get them from, your products are great and you guys always ship freaky fast! Amazon could learn a thing or two from your shipping department.

This is a very good trailer pigtail. It has metal sprung contacts that maintains contact very well. Other pigtails use rubber to make the contacts stay connected and it melts and losses contact. This is truly the best molded trailer plug.


I haven't installed the new plug/cord yet, but I am very happy with the quality of the product. I wanted a durable, top quality, OE style replacement for my Dad's old trailer (doing a gut and remodel). This is it. Etrailer seems to be a 1-stop shop for my trailer reboot. Thanks


Whenever I need any kind of trailer parts, I just go to etrailer. They have quality products, good pricing and great delivery. There is just no reason to waste time looking at other sources. Plus they must have everything imaginable. Awesome selection of parts and the instructions, videos, etc. are great.

eTrailer is the best source I have found for anything trailer. Great company!


Bought as a replacement - original was not long enough to reach the socket on the truck bumper - excellent quality insulating jacket and large gauge wires for brakes, battery, and ground




very well, no problems

Exact replacement for my Fifth Wheel cable. Installation was a breeze. Great service from etrailer as usual.

  • 10 Foot 7-Way Plug and Lead Recommendation
    We have the very similar part # 50-67-005 which is basically just a 10 foot version of the part number you referenced. The 50-67-616 is just a 7-way plug and lead like the one I referenced with only a 6 foot long section of wiring. I attached an install video for you to check out as well.

  • How to Determine Wiring Functions of 7-Way Wires on a Truck
    I don't know the color codes for your trailer connector so you will need to use a circuit test like part # PTW2993 to determine the function of each wire, label them, and then wire to the 7-way. Or you can use the chart I attached to see where the functions of each pin on your 7-way should be and then use the previous wiring locations of the 7-way to determine the functions of each wire.

  • Recommended Heavy Duty 7-Way Trailer Wiring That Will Last
    A standard Bargman 7-Way cable like the 10' part # 50-67-005 will have a similar quality as the Hopkins equivalent. If you're wanting something a bit more durable then I recommend the Bargman 7-Way, RV-Style Connector w/ 6' Heavy Duty Insulated Cable # 54006-057. This wiring actually comes with a 1-year limited warranty which initially doesn't sound great but for the world of wiring it's pretty good. Attached are some review videos for you to check out!

  • Adapting a 7-Way on a 2003 Chevy Silverado to a 6-Way Round Trailer Connector on Big Tex Trailer
    If your 2003 Chevy Silverado has a 7-Way connector I recommend keeping the 7-Way that you have # 50-67-005, and using it to replace the 6-Way on the trailer. A 6-Way is not nearly as common as a 7-Way blade style connector. You just have to determine the functions of the wires on the trailer and wire them to the new 7-Way accordingly. The functions on the 7-Way should be as follows: White Wire = Ground Red Wire = Left Turn and Brake Brown Wire = Right Turn and Brake Green Wire = Tail...

    To install the Standard Trailer Light Kit # TL29BK using the Trailer Wiring Junction Box # 38656 and the 7-Way Molded Connector # 50-67-005, you will follow these wiring instructions. Starting with the trailer tail light wiring kit: The white wire will be for ground. The brown wire is for running lights. The green wire is the right turn signal and stop lights and the yellow wire is the left turn signal and stop lights. Then from the trailer 7-way connector wiring: The green wire is...

  • Comparing the Bargman 7-Way RV-Style Connector to Hopkins 7-Way Trailer Wire Connector
    The only difference between the Bargman # 50-67-005 and # 54006-059 is the insulation. The # 54006-059 has heavy silicon insulation that is rated for use in temperatures as low as -67 F. As for the connection on the Bargman vs. the Hopkins # HM20048 it is going to provide the same connection, there is no real difference aside from the style. The only difference you will find overall is that the Hopkins has a length of 11' while the two Bargman connectors have a length of 10'. I have...

  • Can I Use My 12 Volt Circuit From My Vehicle Wiring To Power My Electric Jack.
    Yes you can splice in to the power wire on your (vehicle end) 7-WAY and that will work. Or you could add a connector like the 7-Way Molded Connector w/ 10' Cable - Trailer End # 50-67-005 to the connector on the Electric Jack w/ Footplate - Drop Leg - A-Frame - 25-1/8" Lift - 3,500 lbs - White EJ-3520-WBX and plug it directly into your truck's 7-way when using the jack. Then it will work for you. We also have the Electric Trailer Jack - Drop Leg - A-Frame - 22-1/2" Lift - 3,500 lbs...

  • 10' Long 7-Way Cable With Double Ended Trailer End Connectors
    I have a couple options for you as we do not have the Bargman 7-Way Molded Trailer Wire Connector # 50-67-210 in a 10' length. First you can take a 7-Way Molded Connector w/ 10' Cable # 50-67-005 and add a 7-Way RV Style Trailer Connector # A10-7081VP. Or you can connect 2 Hopkins 7-Way RV Style Connector w/ Molded Cables # HM20086 together if you prefer to have the molded and sealed ends.

  • 7-Way Wiring Harness for 16-Foot Trailer
    We can help you with a replacement 7-way trailer harness for your 16-foot trailer. All such items are shown on the linked page. These include plugs-only, such as # PK12706, which uses your trailer's existing wiring; pigtail plugs like # 50-67-005 that are available in many lengths; and also complete units like # e99011 which is a 7-way plug with cable and wiring junction box. If you are referring to a replacement 7-way socket for your 2006 Nissan Titan then you can use # C55774 from Curt.

  • Can 7-Way be Spliced Into Equinox Flat Tow Wiring
    You will need an adapter as opposed to splicing in the 7-Way Molded Connector # 50-67-005. For example the RoadMaster 7-Wire to 6-Wire Flexo-Coil Kit # RM-146-7 will connect your RV's 7-pole to the 6-pole round on your 2014 Chevy Equinox. There is also an adapter, the Mighty Cord 7-Blade to 6-Pole Connector Adapter # A10-7276VP that is a possibility if don't need any type of extension like the Flexo-Coil Kit provides. I've added links to video reviews for you to check out as well.

  • Wiring Lights to Junction Box on Trailer
    To wire your trailer and 7-way to the Junction Box Trailer Wiring Junction Box # 38656 you simply need to attach your trailer 7-way like 7-Way Molded Connector # 50-67-005 to the box with Ring Terminals # 44-5310A. The Optronics LED Trailer Tail Light # STL78RB is a three-wire light with ground, tail and turn signal/brakes. You should have wires run to attach the lights from the light to the appropriate spot on the junction box, depending on how you wired it from your 7-way. I have added...

  • Width and Load Rating of 4.70-8 Tires Versus 4.80/4.00-8 Tires
    A typical 4.80/4.00-8 tire like # AM10002 will have a tread width of about 5.7 inches. Two load range B tires in that size would have a combined load rating of 1180 lbs. A load range C tire in 5.70-8 like # AM10012 would have a section width of 5.9 inches and a combined load rating of 1820 per 2 tires. Both tires are compatible with an 8 x 3-3/4 inch rim. The 5.70-8 tire is about 2 inches larger in diameter, which would make the trailer sit right at 1 inch taller that it currently does. If...

  • Could EZ Connector Pogo Cable Holder Help with Fifth Wheel Wiring that Breaks around Corners
    The EZ Connector Pogo Trailer Cable Holder # 319-TCP011602 that you referenced can be installed on fifth wheel trailers like what you have but if you are breaking trailer wiring when making sharp turns that indicates to me that you have too short of a wiring harness. I'm not sure what length you have now but we have the part # A10-7W6 which is 6 feet long, # H20046 which is 8 feet long, and # 50-67-005 which is 10 feet long. Another option is the # 54006-044 which is an 8 foot coiled...

  • Adding Electric Trailer Brakes to a 3,500 Pound 2001 Car Mate Trailer
    The first thing to check for on the trailer is whether or not it has brake mounting flanges welded to the ends of the axles. A brake mounting flange on a 3,500 pound axle would look like # 4-35. If there are no brake mounting flanges they would have to be installed to add brakes to the trailer. The brake assemblies do not come with hub and drum assemblies so those would have to be purchased separately based on the bearing numbers on the current trailer hubs. The bearing numbers are stamped...
