N-902 AUTO TRIGGER CIRCUIT
This new device was designed to supply +12 volts to activate aftermarket components with OEM decks that do not have electric antenna control leads. The N-902 works by sensing speaker voltage from terminals of a readily available speaker. When the speaker voltage is present, the circuitry activates and +12 volts DC IS produced on the green wire.
