Hey guys in need of desperate help i bought a third gen camaro with the dash removed and jave no idea how to wire back up any help on wiring and installation will be greatly appreciated.

 

Your best bet is to go to a junkyard and pull the entire interior wiring harness. That in itself is going to take you a while. You will have to remove most of the dash to do it. I would plan on 2-3 hours so you can take notes and bring tape and label stuff. If you are going to be a minimalist with the car you can buy a painless kit or wire it yourself it you have good wiring skills.
