What colour wire controls the power antenna on a VR Holden Statesman?

Hi i am installing a pioneer cd tuner with usb into my sisters car for her and i need to know what colour wire coming from the stock wiring loom is for the power antenna so when the cd tuner is turned on the antenna will go up and go down when the head unit is turned off - i know the wiring on a cd tuner. its just the wire for the power antenna i need to find as i already found the speaker wiring + power and ground on the wiring loom would it be yellow/red wire for power antenna?
