🚚 Nilight Heavy Duty 7 Way Inline Trailer Plug with Junction Box - 8 Feet, Weatherproof Wiring Harness for RV Automotive Cars - 2 Year Warranty Review

I had everything connected. went camping and all the bulbs were swapped, i had to check every wire and brown/amber was swapped and red and green were. It should work fine now, but took hours to get working (it's not my truck or trailer). This is a plug that has one color and switching contacts.

I wanted to add a reverse light to my trailer and used this connector to connect all the wires without the hassle of wiring. I appreciate the diagram to help with the installation. Just remember to route the cable from the white box to the bottom of the trailer. Now that everything is done, everything looks very clean and professional.

People complaining that the wiring in the packaging is wrong obviously haven't read the instructions. The seller/manufacturer will provide you with a printed, full color diagram showing exactly what each wire does. Anyway, the box and plug are great. The plug cord is good, thick and very long, and there are some extra rubber grommets in the box to cover the cord hole to keep water out. You will have to buy some ring terminals in the box, but overall this is very good quality and an affordable…

I don't want to make a story so that's it. The plug is not interchangeable like most 7 wire plugs and honestly looks like they just threw the wires into a block of plastic and molded it into a plug for no rhyme or reason and melted it all together. If you try to match the same colors at an intersection, about half or more will not work on your trailer since yellow is not a left turn and green is not a right turn. They're all just random, so in the end I had to cut a new connector and install…

I have purchased several of these types of trailer wiring pigtails. I'm not sure why some are wired differently than others. Here are the wire colors for those who want to wire it up. white = earth. Black = 12V charge from vehicle, Yellow = spare/center pin on connector. Red = left turn signal/brake light. Green = parking/driving light. Brown = left turn signal/brake light. Blue = trailer brakes. This kit only comes with one set of nuts for internal connections, so you will need to remove the…

Looks good at first glance, looks good after installation too. Now let's try the headlights. found that the molded plug did not match the industry standard, color code. It's okay, I'll just figure out what's what. Got room for cables, identified very crappy headlights yet. No, let's go back a moment. I completely rewired this simple 4 wire pendant. It wasn't a hard job, nor should it have been. After sorting and rechecking the truck and trailer, I determined the problem was a bad connection…

For the money this is a really good and easy way to hook up a trailer. Trying to connect a couple of marker lights as well as taillights and then a pigtail to T-bars or locks is tedious and eventually leads to failure due to corrosion. For my last boat trailer I used one of these and then "finished" all the other lights. I had to extend some of the bulbs but using solder, heat shrink tubing and spraying hot glue into the heat shrink tubing before hitting it with a heat gun made a very good…
