I think blue black is might be oil light, or alternator. But it might unrelated. Can you start the car, and see if you got something that doesn't work?

Hey guys i started chopping and joining my loom to the tigra a plug i have done all the colour matching and im left with a few wires that i cant match to the 9 pin plug. Which is fine according to the guide i followed found here http://www.allcorsa.co.uk/forums/showthread.php/wire-xe-let-41385.html?s=1fc4ab3b2659af2bf40de5532233408d& but there is no mention about a wire i have left which is showed in here the wire is blue and black stripe or black with blue stripe whichever way you see it. Does any one know whats this wire is for? Thanks
