Wiring Diagram Needed!

Hi, I have a 99 GA GT, but has a front end damage... Some wires are cut, there are some different colors but others 5 o 6 wires or more are black, i need the wiring diagrams to fix that problem, or, some one know if all black wires on front of the car (front of radiator and condensor, these wires goes to coolant tank sensor, cruise control module, lights, etc) are ground?...

Thanks guys...

If you know anyone who works at a gm dealer they might be able to get you a schematic for the car, or you can find one in a haynes manual. Hopefully you don't mess up airbag wiring, if it goes off it takes several days to get the taste out of your mouth, and they don't taste very good...
