Fuse and relay box (internal and external)

[jmh474]

So I'm alittle stuck I'm trying to identify the cables going to the fuse boards, I don't really fancy stripping every cable to identify each cable I need, so I'm hoping that there is a colour code schematic out there some where or is there a way to test from the fuse board connecter as I have the sealed one's thanks.

I have a Fiat punto 2004 1.2

If anyone needs more information please just ask.

Iv posted these pictures for illustration only these are not of my car
