That's almost certainly a molex 'mini-fit jr.' range connector. Farnell part number 151-871. The contacts are separate.

Failing that, it will be a Tyco 'mini universal mate-N-lock', farnell part number 133-670. Again, the contacts are separate.

The molex connector is from the same range as the tuner plug on the empeg dock. Check if it's the same.
