I dont know about ford wiring but on aftermarket units its the blue (power antenna) wire. With the ignition and head unit on, test the wires with a mulit-meter or test light and note which ones are hot. Turn the head unit off but leave the ignition on and re-test the wires, the one that is dead is the wire to the remote on the amp.
