Having put together dozens of 7 pin trailer connectors, I wouldn't have thought I'd be using this pre-made cable. After installing it, I don't think I'd do it any other way! It's a quality molded cable with fine stranded cables. It looks better than individual wires in a wire loom or much better than black tape! Using a water tight electrical connect at a exterior grade junction box, I had plenty of room to terminate and connect to trailer wires. Buy it!
