Red/Green is Battery hot - power on at all times.
Pink/Yellow/Green is accessory - on with the key.
Some aftermarket radios use RED for battery and yellow for accessory, others reverse that; look at your new radios' manual to see how they want it wired.
This is how the 05 service manual says things are set up, keep in mind actual fuse numbers can vary year to year and sub-model to sub-model.
