I recently purchased 3 different makes of connectors. This one was by far the superior one. It's heavy gauge of wire, sturdy casing and great waterproof seals make it a "buy again" item.
This was a custom application for a motorcycle sidecar. Easily tapped into wiring harness with the 12" section, and plugged in the 8' section to get power to the turn signal, tail, and brake lights. Very high quality waterproof connectors tuck out of sight, and the wire gauge and colors were exactly what I requested to match the stock wire harness colors. Communications were flawless both ways. We're very happy with the workmanship, price, and speed of delivery.
I only needed new pins but decided to get the complete set because they are extremely sturdy and easy to use. I put the connectors in my car toolbox just in case. I would definitely recommend them to anyone.
