I needed to install a new set of Boom Harley Davidson Cruiser speakers and the cable connecting one speaker to another was too short due to the location where I was to install it. After a long search I found out that the connection cable (6-pin DIN plug - socket) was the connection cable for the PlayStation 2 (or computer mouse). This 3' fits perfectly. You just need to use heat shrink tubing to close the connection and make it waterproof. The seller delivered promptly.
