The Bargman 7-Way Molded Trailer End with a 6-foot cable is wrapped in heavy-duty blue silicone insulation that stays supple even at temperatures as low as -67 degrees Fahrenheit. Gone are the days of struggling with rigid cables that compromise connections in cold weather.
Forget the frustrating loose connections that lead to flickering lights and faulty braking systems. This meticulously designed 7-way molded connector ensures a reliable link between your trailer and towing vehicle. With robust silicone construction, it keeps moisture and debris out, ensuring your lights and brakes always function correctly.
Whether it's your snowmobile or boat trailer, this trailer end connector supports various trailer functions through its multi-colored wires—built purposely for intuitive connections. The plug features customized color coding like the Black wire for brakes and Red for hot lead, ensuring a straightforward setup that empowers you even when the standard codes don't apply.
The double-wipe design in the connectors ensures they mate snugly for an unwavering hookup. Even though it's crafted to fit securely with most connectors, this makes sure you have peace of mind every time you tow without fearing disconnections due to minor mismatches.
Designed to withstand harsh terrains and rugged use, this plug's construction prevents wear and tear. Although it's super flexible, users have noted that it's also incredibly sturdy, making it a long-term investment for any persistent tower.

Good quality cable and holds up in the elements. All of my trailer lights have been working as they should for the past year.
The bargman 7 way moulded trailer end is a high quality unit. I have been using it for a year now and it has performed flawlessly. The sturdy moulded plug ensures no moisture can get inside. Both the insulation of the individual wires and also the outer sheath are made of silicone and remain flexible even at canadian winter temperatures. There is just one way I think the unit could be improved. The outer blue silicone coating is thin, and not very abrasion resistant. If it contacts the grouns at all, it will quickly wear through. Just a little thicker sheath would be nice.
Overall I am very happy with my purchase, and would certainly purchase again

Really like it as it's the first tail with properly sized brake, batt charge, & ground wire.
Only slight negative.
Silicone jacket was quite attractive, but in reality it's rather thin and not bonded tightly to the bundle (it wrinkles up easily when bending back over the end of the tongue when not in use. Will see how it holds up over longer term.
That said, the blade connections are holding up well after a year (w/no loss in conductivity due to some alloy coating & associated fretting/corrosion as some other pigtails do)
Did apply some high quality dielectric upon installation.
Aside from some minor mounting issues because the bracket DOES NOT fit the plug assemble it is a great product. Used as a 60 amp battery plug on my dump trailer. Took care of my dead battery issues. Can't beat E-Trailer...…Great customer service.

Plug has served very well. Used as a high output charging plug for a dump trailer. Still nice and tight, holding up really well to lite commercial use.
Converted my car trailer from surge brakes to electric
Used this pigtail and it worked out perfect

A year in and this has worked great. My old pigtail was pretty nasty as the trailer used to be a rental trailer so it received abuse and there was no pride of ownership as if it were your own. was of good quality and has held up perfect
Good quality. Super flexible which is what I was looking for.
Use on a boat trailer. Wish I would have found this years ago. I have lost count of the trailer connectors I have replaced over the years, the ones that you have to connect the wires inside the plug. They just got rusty and quite working. I used the junction box and mounted it higher so it would stay dry. I also put the battery in a small water proof ammo box, keeps dry and lasts a lot longer.
Great product at a reasonable price. Fast shipping. Very happy. Better connection than standard plugs plus not stiff in the winter time.

Harness is still flexible and works as it should. great product. Thanks etrailer
Good quality
Love the flexibility of the cord in cold weather. But where the cord connects to the plug, that has seperated. Still working, but do not know how long it will last.

Still good as new! Fits tight and cord is still supple.
I have bought a couple of 7 pin trailer pig tails and a junction box. Everything has been shipped promptly and very well made. I'll be getting all my trailer parts from etrailer. Great people to do business with
It's the nicest. heaviest built harness on the market with heavy gauge wire and the best part is its sealed from elements and only harness I buy, wish more suppliers carried it.
The flexibility of the cable is wonderful in cold temps; just what we were wanting. However, the plug end doesn’t really engage well (stay put) with the receptacles on our vehicles. But, I’d still buy more just to have the super flexible wiring.
Purchased for my snowmobile trailer. This is a great wire that stays flexible in the cold weather.
I like your website its got everything I need for my trailers and will come back and order again. Couldn't find any of these products locally found everything on etrailer.com. Great site.

Meets the needs of most hitch trailer connections. Used throughout our farm. Good service and followup.
Great product, purchased this on a -18 F degree day when my non-arctic rated harness sheath snapped. This one is very flexible even in the really cold temps.
Best harness I’ve had ! Brakes finally work !
Quality product. A good option for those in extreme climates.

Very well! We had Sled Dog Tours for months, in sub-zero temperatures and multiple feet of Snow.Looks like new!
The wiring was all wrong! Had to trace every wire to see where it was going on the whip

The color coding on the 54006-009 trailer connector cable may be different than the cable it replaces, which is why we list which wire color feeds which circuit. This information is on the product page above.
Great product. Well built and will work mu by car trailer.

Holding up well - in spite of appearing unusually thin outer insulation. Properly gauged brake, charge, & ground remains an outstanding choice.
