Astra 2004

I need help with my astra 2004 I had to get the key barrel replaced but the guy I bought it from cut the wires nears the barrel not only that he cut the wires in the ignition switch.

Now I've got all the parts and put her together but there is a point in the ignition switch that needs two wires And I don't have 2 spare wires. I can't find a workshop manual for free download can you please help or give advise.
