Hi,
I've bought a mini with a.. less than stellar wiring job on the radio.

I've so far identified 12v and grounds obviously. The plug it all goes into has 12v going into what's supposed to be switched 12v. I've identified wires which are supposed to be the speaker wires but there are wires that go into the engine bay's wiring harness and have varying coloured wires.
Where can I start looking at what all these wires do?
