Do you have a volt meter or a circuit tester? You should have a constant power and a switched power. Constant power will give a reading without the key in the ignition. The switched power will only come on when you turn the ignition key past the locked position. As stated - the power wires should be red (perhaps yellow). Ground should be brown. Blue is power antenna. Two-tone wires are for your speakers. You can test speaker wires without a volt meter by hooking up both ends to both ends of a 9-volt battery. When you do so, the speaker connected to the wires will make a *scratching* sound.
