New Stereo

im installing a new cd player in my sister focus. :confused: could someone help me out and tell what color wire are the power and stuff. i know what the speakers are but thats it. some one please help me out

- Black is Negative
+ Red is Power
X Yello is consant/remote


Connect the Black wire to a ground somewhere
Connect the Red to the main power terminal on the battery
Connect the Yellow to a fuse or switch that had power when the car is on, but no power when the car is off ( I have mine connected to the parking lights).

i know what those wires are but i need to know what the wires coming out of the focus are.
