could anyone tell me which wire is which please

I have...

red wire
brown wire
brown/red stripe
white/blue stripe

then 4 others which I assume are for the speakers

am trying to install new headunit into mates polo cos it got nicked and they hacked the wires so there are no connections, but so far have managed to blow fuse several times

thanks for any help

I'm pretty sure its this:

Red = Live
Brown = Earth
Red/Brown = Switched Live
Blue/White = Nothing (Not connected to radio in car, and not even mentioned on wiring diagrams!)

Hope that helps,

John

cheers... great help

all installed and working properly now... lets just hope this one doesn't get nicked now!

Its so frustrating when people nick your hard earned stuff.
