The 112-PU wire delivers power to the "VIBE" fuse and the "GAUGES" fuse when the main relay is energized. The 103-YL wire distributes power from the "VIBE" fuse to the throttle switch. The 123-WH wire distributes power from the "GAUGES" fuse to contact "1" of the vibratory tachometer.
When the throttle switch is in the HIGH SPEED position, power transfers into the C906-PU wire. This wire delivers power to the vibratory control switch.
When the vibratory control switch is in the OFF position, the circuit across the switch is open. When the vibratory control switch is in the ON position, power transfers into the A990-BU wire. This wire transfers power to the amplitude selector switch.
When the amplitude selector switch is in the HIGH AMPLITUDE position, power is transferred to the high amplitude solenoid. When the amplitude selector switch is in the LOW AMPLITUDE position, power is transferred to the low amplitude solenoid.
The 450-YL wire connects contact "3" of the vibratory tachometer to contact "1" of the vibratory speed sensor. The 451-BR wire connects contact "2" of the vibratory speed sensor to contact "4" of the vibratory tachometer. The speed sensor drives the tachometer with a series of magnetic pulses. The pulses cause the needle in the tachometer to move.

The 112-PU wire delivers power to the "VIBE" fuse and the "GAUGES" fuse when the main relay is energized. The 103-YL wire distributes power from the "VIBE" fuse to the throttle switch. The 123-WH wire distributes power from the "GAUGES" fuse to contact "1" of the vibratory tachometer, to contact "A1" of the vibratory controller, and to contact "F3" of the vibratory controller.
When the throttle switch is in the HIGH SPEED position, power transfers into the C906-PU wire. This wire delivers power to the vibratory control switch.
When the vibratory control switch is in the OFF position, the circuit across the switch is open. When the vibratory control switch is in the ON position, power transfers into the A990-BU wire. This wire transfers power to contact "85" of the vibratory relay and to the contact "10" of connector "C215". At connector "10", power transfers from the A990-BU wire into the A935-PU wire. The A935-PU wire transfers power to contact "5" of the amplitude selector switch.
The vibratory controller monitors the position of the amplitude selector switch and the position of the vibratory frequency potentiometer. When the amplitude selector switch is in the HIGH AMPLITUDE position, the ECM generates an output signal from terminal "B2". The strength of the output signal is proportional to the input signal that the controller receives from the vibratory frequency potentiometer. The output signal is transfered to the high amplitude solenoid through the A784-YL wire.
When the amplitude selector switch is in the LOW AMPLITUDE position, the ECM generates an output signal from terminal "B1". The strength of the output signal is proportional to the input signal that the controller receives from the vibratory frequency potentiometer. The output signal is transfered to the low amplitude solenoid through the A892-OR wire.
The 450-YL wire connects contact "3" of the vibratory tachometer to contact "1" of the vibratory speed sensor. The 451-BR wire connects contact "2" of the vibratory speed sensor to contact "4" of the vibratory tachometer. The speed sensor drives the tachometer with a series of magnetic pulses. The pulses cause the needle in the tachometer to move.
