im thinking of changing the radio to a custon player if anyone knows the colors or where i can find these pictures on this site of what wire is what all i know is red is power lol ... including the speakers in the head rests thanks fellas

 

When I did my stereo all the stock wiring harness colors matched the wires on the aftermarket harness for the deck.

I am sure someone has a more detailed image or step by step type thing but it was pretty simple. It's aftermarket speakers that were a pain in the butt cause of the stock amplifiers on the speakers.

Red is not power... it is illumination, and the wire colors for the stock system can be found in the Sticky thread at the top of this section called the FAQ for FC.
