Horn: Description and Operation

Voltage is available to the Horn Relay at all times through the HORN/DM Fuse and the ORN (240) wire. When the Horn Switch is depressed, one side of the Horn Relay coil is grounded through the BLK (28) wire. The relay is energized. Its contacts close and battery voltage from the ORN (240) wire is supplied to the Horns through the DK GRN (29) wire. The horn is grounded through the horn mounting bolts.
