- One way to do this is use a horn relay. Use the signal from your horn
- button to actuate the relay. The horn itself would be connected directly
- to the battery, or an appropriate power connection, through the proper
- size fuse via the high current side of the relay. The current needed
- to turn on the relay is small, but it can connect the other two contacts
- which handle a much larger amount of current, sorta like a starter
- solenoid works.
