Problem With Dash Lights

I recent put a CD player in my 2001 Xterra and stupidly I cut into the harness and now my dash lights dont work, I left three wires left, yellow, yellow/black, and pink. How can I fix this and what went wrong?

Are you kidding? You have to go back in there and retrace your steps. It's almost impossible for someone to help you over a computer.
