Kohree 7 Way Trailer Cord Plug, 7 Pin Trailer Wiring Harness Kit with Waterproof Junction Box, 8FT Heavy Duty 7 Wire Trailer Connector Cable with 12V Breakaway Switch & Plug Holder for RV Truck Camper

Why did you pick this product vs others?: I bought this to help rewire my 21 foot aluminum boat trailer. I ran new wires for my taillights and clearance lights in separate circuits. This junction box allowed me to do that without issue. Now that each circuit is isolated, one going out won't affect the other. The cable connection to the truck is very solid and seems to be much better quality than just a simple 4 or 5 flat setup. While this isn't waterproof, and I am using my boat in salt water, I have it mounted just under the winch. This area rarely if ever has exposure to the salt water, so I am not concerned, especially given the fact that I am using tinned wires for everything. I expect many good years of usage from this. Highly recommend for a custom wiring job.

Perfect replacement Didn’t need the box but cord was perfect

So I ordered this for my Big Tex 70 TV utility trailer, and it works great. A couple of things to note because I saw that some reviews said that the color code was wrong for what they purchased. This is because (and this is a general statement) utility trailer manufacturers tend to use a different color code than RV manufacturers for their wiring. With my utility trailer being the type of trailer you hall a large lawnmower on and and RV trailer being something you would take camping to sleep in. So technically this is color coded for a RV type, but works perfectly fine for my utility trailer which is a slightly different color coding. While the RV and utility trailer industries may not agree on a uniform color coding, the auto manufacturers do agree which is why this can be used for a utility or RV type trailer. If you look at the the front end of this plug it says that red wire which is in the 3 o'clock position if you are looking at it is left turn signal. On my trailers original plug the 3 o'clock position was a yellow wire but that same position also makes the left turn signal come on. That is because the auto manufacturers insist that the 3 o'clock position on the plug makes the left turn signal come on regardless of what color the different trailer industries choose for that wire. So if you get this and are not sure just match what each of the wires do (ie left turn signal) with the wire on your trailer that says it does the same thing (ie. left turn signal). All of that aside about color coding, so far that product has worked great. I thought that it was reasonably priced and I liked that it had a longer length then the original one I had on the trailer. It is also easy to remove, when pulling the cord out of the back of the truck receptacle. My original trailer plug was not as easy to unplug from my truck for some reason. This cord stays firmly in my trucks receptacle.

This plug is molded well and the wiring is solid copper which is a plus. The plug end fit nice in my tow truck and all circuits tested good. The 12V power wire and the ground wire are a larger gage than the other circuit wires which is another plus. Outer cover is a heavy gage and was pliable ever in cold weather when I did the install. The only negative is that the wiring covering color code does not match what is considered a US standard for trailer lights' wiring. You will have to test out each wire lead to confirm which contact it is connected to. Make yourself a color code chart to use for reference before starting the rewiring job.

Great product

This idea of a molded plug and junction box is great. I've always wired my trailers up in a similar way, but this just takes the cake for ease and you only have to worry about water getting into the one side of the plug instead of both sides of the plug. The junction box seems to be sealed up pretty well, but I still coated the inside of it with a marine grade wiring corrosion spray just in case. I did have to re wire the terminals and go off position for a standard 7 way flat rv plug. Don't use the colors nothing will work right. I'll never understand why this hasn't been standardized yet. All 3 of the vehicles I tow with have factory plugs and they are all wired the same, why can't the plug manufacturers use the appropriate colors for the appropriate function in the correct position? End soap box. It works well and I'll be transitioning my other trailers over to this style of junction box and plug. Really does a neat job and tidied up the wiring big time.

Perfect for my travel trailer. Easy to install and hook up.

I had to return it because It was not what i needed. It was very well made but it is NOT waterproof. As it sits, it is OK for a dry land trailer. IMO, It needs a gasket on the box cover to make it more weatherproof, but it will probably do fine without it. I thought it would work for a boat trailer, but that was my mistake.
