illumination wiring

2004 f-150. I have installed an aftermarket head unit with GPS and uses an orange wire for illumination. This F-150 has no Sirrus or amp so its a direct connection to the main radio connector. What wire does the orange illumination wire from the head unit connect into to make the radio lights come on when the headlights are switched on? Is is the red ACC or the yellow +?
