The two remaining wires are for a small speaker (8 Ohm) so you can hear the chimes. This speaker gets mounted in the OEM location under the driver's side dash. Pin 12 on 71-9003 gets grounded in the trunk.[/center]


For those with Logic 7 - will we also have to extend the optical wire to the trunk as well - or will just the 5 mentioned above be fine as well?
