Default Can ecu control a spare wire as a signal wire to a relay?

I read the thread asking if the ecu can control kick down. Well it got me thinking does the ecu have a spare wire that can be used as a signal wire if the ecu see's certin perameters?

Such as a nitrous signal wire. After 3k rpm and 98% throttle it could kick power to a wire which in turn sprays nos? So basically using the ecu as the WOT switch?
