The remote-turn on wire is the wire you are looking for (orange wire on the Tube's harness). This is responsible for turning the Tube "on" and "off," when the power is removed from the circuit. This is connected to a +12v key/on-key/off source, such as the remote accesory turn-on lead on the headunit.
