Got the OLD cassette deck out and want to fit my new Blaupunkt system.
Before taking out old system went on Ebay bought an adapter for my Blaupunkt,to fit my car.Also I bought connector for my Blaupunkt,with connectors on end so you can crimp the car wire to it.
Took cassette deck out and someone has butchered the wiring,they,ve cut off the original car connector blocks.

I,ve sussed out the 8 speaker wires.

There are 4 car wires and I,m not too sure what they are for.

Blue+black-Red+black-Brown-White.
Could anyone PLEASE post this part of the wiring diagram,for my car?
Thanks,Karl.
