red/white - power from fuse box
brown - earth
brown/red - ignition feed
black - aerial and booster (whatever they are)
white/yellow and grey/blue are to do with the lighting. you won't need these for an after market headunit

black/blue - Left front speaker
blue/brown - left front speaker
red/white - right front speaker
brown/white - right front speaker

blue/green - right rear speaker
brown/red - right rear speaker
brown/black - left rear speaker
red/green - left rear speaker

normaly the iso block just connects into most new stereo iso blocks either on the back of the stereo or on the stereos wiring!!!......... the speaker connections are normaly ok its just that when you connect to power wires up sometimes they need moving to a different slot of the iso connector block so the match the cars iso connector..............

in fact i should get a job at a car stereo fitting place!
self taut when i fitted me own stereo! ;D

i also got a haynes car entertainment manual which has lots of info  in it!
