I need to re-install my deck after it alm...

Hi! My car stereo ALMOST got stolen, I caught them in the act and saved my system, but they had already torn out my dash, ripped apart the wires, and disconnected everything. It is a mess! I paid a lot to get it installed originally and I can't afford to pay someone right now to do it again, Christmas coming up and all. I tried to connect all the wires (the little colored one's, some with black stripes) to the matching color. I plugged in the antenna and the subwoofer plug things. But it's not getting any power. I noticed it's missing a fuse, but I don't know how many amps to get, the broken pieces are yellow so I think 20A. I tried it with a 20A fuse in and it still doesn't get any power. I have a 2003 Chevy suburban. There is an orange and a pink wire coming from the car, but none coming out of the deck to connect them to. I am sooo confused and frustrated!!! Which wires give it power?????? Help!!!!!! Where can I find an installation guide? Pioneer no longer supports this model.
