car wiring

ok here is what i need to know. I have a  1992 saturn sc and the wiring harness was cut off ok. i have a awia head unit that i want to put in so what im asking is what wires from the radio do i hook to the car wiring here are the colors and name of both sets of wires i left out the speaker wires because i can easily figure them out ok

car wiring diagram

constant 12v+ - orange,switched 12v+ - yellow, ground-black, Illumination - gray, Dimmer - brown ok

and the head unit wires are

red-to power (acc) -(yellow-to battery direct)(black-ground)(blue-relay switch)

so if anyone can just tell me witch one to hook together and one more thing witch one would i hook a amp remote wire to please help me thanks

blue/white wire from awia radio, should be labeled as an amp turn on wire or something like that.

if no blue/white, use blue

if no blue, use the acc wire (red)
