Audio Installation Impaired, Celica wiring diagram anyone? Options

[Doge]

Ok...i just got a kenwood kdc-mp919 and im about to install it. And i figured out that i cant use the factory amp so i have that taken out and am using the harness that plugged into the amp. I've been working for about an hour so all i have are the ground and two power wires hooked up. (black, red, yellow) Thing is...when i turn the car on the deck doesnt turn on. Do i have the wrong wires hooked up or what the hell am i doing wrong? I know i dont have to wire everything to make the deck work...i just want it to turn on so i know i'm getting somewhere. Does anyone possibly have a diagram telling which colors are for what? That would help alot with both this problem and the time consuming process of testing each speaker wire afterwards to see which wire goes to which speakers. So if anyone could help i would love the advice. Thanks alot. Steve-O
