i'm going to be putting a cd player and a set of component speakers into my friends 99 chevy s-10 pickup. it came from the factory with no stock stereo just a blank plastic panel where the headunit would be and grille's in the dash and doors but no speakers in them...I was just wondering if since there is no stock anything will there be a wiring harness for the new cd player and will there be wires in the doors/dash for the speakers or will I have to wire everything in from "scratch"? Anyone had an experience with this
