Replaced old cord with new one. Exactly what I wanted at a reasonable price. That is why I always check etrailer for parts I need on my RVs. the cord is durable and is exactly how it was explained in its description. 672196

This was an exact match to the wiring of my 2009 forest river 27' salem toy hauler. I purchased the 10' cable which is 2' longer than the stock cable. I did that so I would have extra cable to add a new end to if I have troubles later on. The Product works perfectly after installation . My reason for the replacement was a failure of the stock plug end. No complaints about the stock one. It lasted 10 years which I believe is a good life span for any plug. This plug seems like with proper care and corrosion protection it should have a long life as well. 705480

The delivery was reasonably fast. The service tech, Nicolas C., with whom I talked and placed the order was very knowledgeable and pleasant. The cable is for a 5th wheel travel trailer to a 3/4 ton pickup needed to replace the factory one-foot too short cable with a connector whose female metal connections had lost their temper and thus valid connections to distribute voltage and current from the truck to the brakes, batteries, and refrigerator. The new cable seems to have solved the problem. The etrailer site had good wiring diagrams and installing instruction for many types of trailers. 584316

Ordering and shipping on time was great. easy installment. Only draw back is the longer I pull my trailer the more the brakes apply pressure and I have to make adjustments to keep brakes from locking up. But I would and suggest buying to a friend. 734844

  • How to Rewire Vintage Trailer with 7-Way Connector and Parts Needed
    Most of us aren't electricians, but that doesn't mean wiring a trailer is beyond us. It will take a little bit of time, but I wouldn't consider it a difficult DIY project by any means. So, to wire your 1977 Serro Scotty vintage camper, I recommend using the following parts: - Mighty Cord 7-Way RV-Style Trailer Connector # A10-7W6 (6 ft long) - this is a high quality molded trailer connector with corrosion resistant terminals. - etrailer Trailer Wiring Junction Box - 7 Terminal # e99009 ...

  • What are the Different 7-Way RV Wiring Configurations
    There are two different styles of 7-way wiring typically seen. Traditional and RV Standard. The pins all have the same functions but the difference is the wire colors. If you check out the picture I attached you'll see the two different versions in the left and center diagrams. The 7-way part # A10-7W10 that you referenced uses the RV standard style.

  • What are the Correct Wiring Connections Between the Trailer and the Tow Vehicle
    I have attached a wiring diagram that will show the typical arrangement of the towing wiring on your vehicle and the corresponding wires on the trailer side. The basic wiring identification is as follows: Green - Tail & Running Light Black - 12V Power Brown - Right Turn and Stop Blue - Brake Control Output White - Ground Red - Left Turn and Stop Yellow - Reverse Lights I also attached an article on trailer wiring that can give you more info for you to review.

  • 7-Way and 10 Foot Wiring Harness Recommendation for Airstream Flying Cloud
    The Mighty Cord # A10-7W10 that you referenced is a great option for you. This connector and lead is made from really high quality materials that will last you a long time. The wiring also has heavier gauges of wire than other options too so it wins in that department as well.

  • Why Do Some 7-way Plugs Use Dual Contact Surfaces
    A 7-way (female) vehicle socket like # PK12-707E has a single blade contact; these fit in between the dual contact surfaces in a (male) trailer plug like # 54006-059, # 277-000143 or # A10-7W10 and the connector (type BB) shown in your photo. Some 7-way male plugs will use a single blade contact, such as the plug on Hopkins 7-way extension # HM20049. This item's female socket and male plug happen to both use the single contact. Both types are compatible with each other. The Bargman...
