Radio Question

I just put in a new deck and had to hard wire it since the previous owner ripped the harness out. The small problem i'm having is that the deck doesn't save the clock or memory presets. I just want to know which wire goes directly to the battery so the memory will be kept

Should be the blue/white wire.

P o w e r
Memory (+12v Constant) Blue/White
Ignition (+12v Switched) Yellow/Red
Ground (-) Black
Illumination Red/Black
Power Antenna Yellow/White

S p e a k e r s
Right Front (+) Red/Green
Right Front (-) Brown/Black
Left Front (+) Blue/Green
Left Front (-) Gray/Black
Right Rear (+) Red/Yellow
Right Rear (-) Brown/White
Left Rear (+) Blue/Yellow
Left Rear (-) Gray/White
