PRINCIPLES OF OPERATION

The smart junction box (SJB) supplies the control voltage to the horn relay (part of the SJB). When the horn switch (part of the steering wheel) is pressed, ground is supplied to the horn relay sending voltage to the horn, enabling the horn to sound.

The SJB provides a momentary on then off ground when the panic button is pressed on the integrated keyhead transmitter (IKT).
