    Break out the multimeter and start measuring voltages on the 12v constant line and the 12v switched line.
    Measure voltage on them with the key off, the key in ACC position and then when the engine is running.

    And FYI - That is an M3, not an M2.
    Have you looked in the FAQ yet?
    How about the Wiki?

    Under normal circumstances, a signature would go here.
