Good value on a 7 wire trailer harness
I bought this for an automotive project but the wire thickness was too much so I returned it for a 4-wire harness. Even so they shipped it quickly and it seemed nicely made so would recommend!

Great comms cable.
Wire thickness 14awg starnded copper wire was perfect for generator communication signal. Pulled very easily through 3/4 inch conduit. Colorcode was yel, brown, blue, white, green, purple, red.

We get what we pay for, and that's not a complaint...
I've got over 20 trailers that I run and maintain, including some RV rigs (in case some folks think there is a difference). We use lots of wire, and buying 7 wire makes life cleaner and easier. And the stuff is expensive. Enter Amazon, and particularly, thus item. Price was sooooo low, I took a chance. So hear me clearly; I'm not complaining, but I wouldn't waste my time again. The outer jacket is OK, a bit brittle, easy to slice, and thin. The inner coverings are super soft and trim easy. And the wire? I've never used anything so soft and breakable. Tightening a lug on a plug breaks the wires. Don't even think about letting it dangle for a couple seconds while you orient the next wire to feed. It worked for a very long extension...for now. I will not run this stuff for regular use. It gets 4 stars...because it is what is advertised and it performs OK for the price paid. And that's it.
