You will have 3 main wires
A ground which is normally black/brown
A contstant power wire, which is used to maintain your settings, which can either be red or yellow.
And you will have an acessories wire, which is used to turn the head unit off and on when the key is either in acessories position or out.
to determine which is the contant and which is the acessories you will need a multimeter, and you simply turn the car off and take the key out, and whichever one has power that will be your constant, and the other be your acessories.
The rest of your wires will be your:
front left +/-
Front right +/-
Rear left +/-
rear right +/-
