for got to mention the car had a aftermarket radio in before but the last owner took it out before he sold it to me and i think they bypassed the factory amp because there is speaker wire running though the car..

you have to just splice the wire yourself.

Or in short
A2 = orange dimmer
A3 = yellow
A4 = red
A11 = black ground
Also the pink green and pink blue wires need to be cut and wired to your antenna cable.
