Wiring bonehead needs help with CD player install

[bigcarguy]

Ok, I've got the speakers all ready to go, I just now have to wire up the player. It's a Pioneer DEH-P20 and I just need help finding where to wire it to. There's a red and a yellow wire coming out of the back of the player, yellow marked as battery and red marked as ACC. Now, I look behind my dash and see a lot of wires and I don't know where these two wires should be hooked up to, so if anyone can give me some help(color of wires I can hook into or at least some really good locations) then I could have this thing installed in no time.
