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!

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.
