Heavy Duty 7 Way Plug Inline Trailer Cord with 7 Gang Junction Box - 12 Feet, Weatherproof (12-Foot)

The media could not be loaded. I got this to replace the one that is currently installed on my trailer tongue….difference is; that it’s old & crusty….has been spliced into numerous times…& it’s been cut & extended to reach the vehicle.I believe this product will make install much easier along with making sure i get the performance needed to the correct areas on the trailer.Appears to be of really good thick plastic for the junction box & the 7 flat pin is non serviceable-which in my opinion is great!Keeps from tampering & making things worse-haha!

I used this product to replace my four wire boat trailer plug with a seven way plug so that I wouldn't need an adapter for my vehicles.The new seven wire plug was wired for traditional RV and NOT standard trailer.Instructions are not in the package! The wiring diagram is in this ad, so do yourself a favor and print them or screenshot them for ready reference when installing because I hooked up yellow to yellow (LH turn/brake), brown to brown (running lights), green to green (RH turn/brakes) and white to white (ground). When I plugged the new plug into my vehicle, one light came on. I quickly realized something was wrong.I grabbed a multimeter and used the Ohm function to figure out how the pins were wired and what color they used to wire their plug. I had three of the four wires I used connected to the wrong colors. Using my Ohm meter I was finally able to determine where the correct wires go. There were no instructions on the package. The wire diagram is in the ad, and I didn't see it until after all of this occurred.I've included a picture of how I connected my wiring.It works perfectly, now.

I purchased this cable initially a few years ago and installed it on my camper to replace a corroded and worn cable. I love the big junction box that allows you to wire stuff in with ease. I recently needed a new cable for my utility trailer and didn't hesitate to reorder.One pro tip: The color coding is incorrect and you'll have to figure out what color your trailer wires are and figure out what color the harness wires are. I found writing that out on paper takes the confusion out of it and makes it easy to wire up. I attached a photo cheat sheet if you're converting from a traditional 4-way plug off a small utility trailer.

This item is very sturdy for the most part. The box that encases the terminals is probably not. It appears very breakable even under normal use. I'll probably bubble wrap mine to help protect it. ;-)Other than that, it's quite sturdy. Good cable and terminal strip (color coded too)

Super clean look and easy to check wiring. These colors did not match my 7 way, but I knew that from the reviews. I verified the correct wiring and the terminal made it easy to change and test.I first crossed the left and right blinker. Less the 5 min to swap the yellow and green wires.Several weeks later, my back right light quit. It used the junctiong box to test if the connection to the truck was good. Yes, so I knew the light was the issue. Correct, the bulb was at fault.Worth it.Good value/not so good colors match = Good buy for me!

Hard to install if you have an old RV with bad 4-pin wiring that's been "repaired" by a lot of people over the years each apparently drunker than the last, but once we figured out what was what it did what it was meant to.From what I read, there is one made for cargo type trailers, and a different one made for RV's - I didn't know that till after I bought it, but if that matters to you, pay attention. No idea what this one is.

Great solid product. The block box is solid and appears to be water resistant, time will tell. The plug however is solid rubber and makes for a very TIGHT fit. We have do gently sand the plug down a little in order to fit easier in and out. Great product though, I think it will work great for replacing lights and wires on the trailer in the future.

Installing trailer wiring in something that would normally never be considered a tow vehicle. I'm running all the wires from the vehicle to the junction box, and then I have one nice, neat, insulated harness to go out to the hitch. I cut the trailer-side connector off and got a vehicle-side to attach to the end.The junction box has inlets (with extra grommets!) for wires on all sides. There's plenty of room in the box to work and stash extra wires that ended up long. Construction seems solid, the cable is thick and heavy. They even thought of little things, like metal straps in the box to retain the wires (keep them from getting pulled out) and painting the wire post tips for extra visibility. Very well done.
