I recently purchases a New Metra Turbo Kit and Wiring Harness to install a new head unit in my '05 Mini Cooper S only to find out that they do not work with the Harman Kardon premium sound system. I paid about $27 for the pair and I'm looking to sell the set for $20. They will work to install any after market head unit in any MINI 2002 and up as long as it is not already equipped with the premium sound system. The exact part item model numbers are:

Install Kit: 99-9302
and
Wiring Warness: 70-9003
