Metra 70-9003 Receiver Wiring Harness
2006 MINI Cooper
Crutchfield Customer Review (What's this?)
They advertise this as a plug and play for the Mini Cooper with harmo kardon sound system. But it will not work unless you purchase a secondary plug and play harness from the UK. If not you have to rewrite all of your speakers to bypass the factory harmo kardon amp.
