I used this connector harness to add electric brakes to my trailer. With the color coded wires, it was an easy task to connect everything up. The socket connects up to the 7 way factory connector on my F150 pickup. I recommend this connector harness for similar applications.
A perfect replacement for my RV trailer connector. Very easy to install. Works as intended.
Product is of high quality and arrived on time shipped as promised.
Very easy selection and purchase.
The Mighty Cord 7-Way RV Style Trailer Connector w/ Molded Cable was spot on! After perusing through numerous websites and [online vendor] looking for this very specific cable and molded connector with 10,12, and 14 gauge wires, I was finally directed to Valterra which actually showed the product on their website. But they do not sell the product. The gal who I talked to told me to go to etrailer.com and Bingo I found what I needed. Shipping was fairly quick and after comparing the wires on the existing cable to Mighty Cord the gauges and colors match--making splicing a breeze!

The product has performed flawlessly! The key to the satisfactory results of this male connector with cable was bending the plate on which the female connection is attached on the back of our Expedition perpendicular to the ground. When the two are solidly coupled, the female receptacle cap grabs onto the top “horn” on the male plug securely.
Cable recd today without any labels, paperwork, or schematic detailing what the normal wiring represents.
All was not lost as I searched etrailer.com & found wiring instructions for detailed usage.
Cable, wiring, & connector all of good quality.

1 year later the cord has been subjected to all types of weather & along with road debrisfrom our motorhome. The cord still looks new. No damage to insukation or connectors. Thanks for delivering a lasting product.

Thank you
After damaging my electrical cable that connects the motorhome to my truck in-tow. I ordered a new 7-pin cable with connector and a 6-pin connector. I received both within four days and after an hour of rewiring I am back in business. Thanks for the great service etrailer.
Contacts corroded worse than anything I have ever seen in my life after one dip in the ocean. Might be acceptable for fresh water but it's definitely not ok for saltwater use.

My recommendation to best protect trailer wiring from salt water is to use split loom, spiral wrap or braided sleeving to protect your trailers wiring. Use heat-shrink tubing - the kind with the melting inner wall - or liquid electrical tape. On incandescent-bulb sockets, use dielectric grease to protect against water and eventual corrosion. We offer wire loom, heat shrink tubing, liquid electrical tape part # SWC50122, and dielectric grease part # 11755.

The only less than stellar part Ive purchased from etrailer
Works fine and seems to be made well. Have to push hard on the plug to seat it on the connector for the cap plug latch to engage the plug body.

I purchased this item to provide charging for the boat battery while the boat is towed. No issues with the item currently.
This worked very well to replace my plug and wire that was dragged down the road accidentally. The cord is sturdy and flexible. It installed easily. After 1 year it is still working great. Be sure to use dielectric grease on the contacts.
I ordered a 7-way trailer wire for my camper to replace a damaged one. Easy installation and worked as if it was factory installed. Very pleased with this product and etrailer.com
8 ft cord was perfect for my 2014 jayco !!!
Worked perfectly after I had shredded my original. (Here's a tip...don't let the cable drag while towing :) )Quickly installed using existing wire nuts. 30 minutes start to finish. The plug end seems like it doesn't lock in quite as securely to the truck socket as my original did. Time will tell
good quality works great
Easy to install the connectors are smaller than original and hard to push in but will get easier with more use.. overall a good replacement
Exactly what I needed and fast shipping. Great replacement for my OEM pigtail.
Haven't installed it yet. But fast deli very!!
Excellent 7 wire plug. Repair went very well.
When you’re up there and it still working flawlessly

Still working great. 19 thousand miles on trailer since installed.
I usually dont do product review but thought I would give a shout out to an outstanding company. George and the team have delivered everytime I've ordered from them. Excellent service. Will continue to order from this great company.
One year of use, and it works great with no issues at all. Nice and beefy, and the connection to the vehicle is really solid. No complaints at all.
So far so good
