Anybody has a wiring diagram for the 2003 Mini Cooper r53?

Cool Try This

Disconnect your battery terminal (negative) for about 5 minutes then reconnect. This should reset your ECU. It may run rough the first 2 - 3 times you start it while everything resets. If this doesn't fix it, find someone who has a code reader and get the code number. It sould like a bad plug wire to me. Nothing a wiring diagram will help with.
