normally if a radio has an illumination wire you would connect it to the dash lights in the car. that way they are dimmed with the dash light dimmer. also most times cars have a radio fuse but a constant source marked for the back up does not exist.
connect the red wire and orange wire together, if when you shut the radio off the lights go off. if they dont go off when the radio is turned off hook it your interior light breaker, so when you turn the interior lights on the radio lights up. or not hook it up at all
edit the yellow wire is the memory feature. i think the best way to hook it up is to the main dc breaker, that way when you are the boat it will keep the settings when you shut the radio off. but when you shut the boat down for the week you wont have the drain, even thou it is a really small drain, then you will have to reprogram it thou
