I've been search in the internet and the Wiring Diagram Galley on this forum for the wire colours that are connected at the back of the stereo but non of the colours match up at all (Or i just find find a diagram in the gallery)...

I've asked a few mates of mine who are mechanics and they havent seen this type of wiring before, his words were "it looks like a rainbow"

He said the main 12v supply is suposed to be red, the ignition wire is yellow and ground is black, but i dont have a red, yellor or solid back. There is Green/Black, Black/Green (but it looks like Green/Black), Black/Orange, Orange/Black (but again it looks like Black/Orange) and a Blue/Black, then there is the 4 speak wires which are on a seperate connector but i cant remember the colours of them of the top of my head...

When i've search on the internet i cant find a referance for any of the colours shown above so if anyone knows which wires do what then i'd really appreciate the help!

Also i got kinda lost in the Gallery as i have only just started leaning schematics at college lol

Thanks,
