Electrical Wiring Opel (Vauxhall) Astra 2005

Hi,

does somebody know where i can find electrical wiring diagrams of the
Opel Astra model 2005 (newest model). I inspected my car and found
numerous loose connectors. I would like to know what they are used for
to maybe build me soms extensions.

I'm looking in particular for connecting my nokia CK-7W carkit to my
CD70 NAVI audio system, but i would also like to have som wiring
diagrams or explanation of all the loose connectors.

Regards,

Tom
