Can anyone point me to the following diagrams for a 2004 Cadillac Deville DTS with Bose and without Navigation?
Diagram of the wires from the head unit to all of the speakers/amps
Color code for each wire
Specifically, I want to just add a subwoofer, so I need to locate the Accessory Wire and Audio Signal Inputs (+ and -).
Also, I need the Ignition Wire in order for my Radar Detector to be on only when the car is o).
