Filluck SAE 7 Way Trailer Plug Cord Wiring Harness with Junction Box,Heavy Duty Waterproof Double Prongs Connector, Light & Brake Control 7 Inline Trailer Cable for SAE Standard (8ft)

Great Connector. Easy to wire to the trailer's electrical system.

I love these. Obviously you’re only putting one in after something bad happened to your last one. Installation on these is fast and easy. Color coating makes it a breeze. Zero stress install. I bought this particular one for the bright orange ends. Hopefully, I will see them and remember to disconnect the trailer plug before driving away L O L

It is pure copper as described. Looks well made. Wire gauges were correct as discribed. The box does ping my OCD since it's color coded and wired correctly, but its internal labeling is wrong (see pic). Tailer cord is 7.5' from box exit to trailer plug, but it is actually 8' if you include the longest wire attached inside the box.I would probably buy this again, since the other I purchased from Amazon, that was their "overall pick", advertised pure copper wire, but was actually Copper Clad Aluminum. (I hate bait and switch stuff)

Imagine my surprise when wiring my trailer only to find out that the plug is just thrown together. It took me an additional hour to ring out the individual circuits with a voltmeter and get them sorted out in the junction box. Out of seven wires, only two were correct. I feel bad for whoever I sell this trailer to.

This makes hooking up trailer light easy, has a box for all your connections keeps the wire from the weather good product.

Quality is ok. Don’t even try to use the wiring diagram that comes with it. Wrong colors in the wrong positions. I had to ohm each wire to the plug to know what color was what. They got 3 out of 7 right

It works great and is better quality that I expect. I had a few of the cheaper ones that fail quickly but this thing is doing fantastic. Love the clear lid as well.
