Circuit Descriptions

The circuit description describes how the system works electrically. It details how power, ground, inputs, and outputs are supplied to the system's related components. The circuit description also explains the communication and interaction of all components that affect the operation of the system.

Battery positive voltage is applied at all times to the horn relay terminals 85 and 30. Pressing the horn switch grounds the horn relay coil on CKT 28 (BLK). The relay coil can also be grounded on CKT 28 (BLK) by the Dash Integration Module (DIM). The horn relay applies battery positive voltage to the horns on CKT 29 (DK GRN) when energized. The horns sound until the horn switch is released or the DIM signal is gone.
