Anyone know if the button you press for the horn makes the connection for the ground or does it supply the positive energy?
I'm installing a new hella and i need to know which way to hook it up.


Thanks

Hitting the button supplies the ground.

Kinda messes with your head when you hook up your new horn and it just blares when you turn the key on, huh?

Hitting the button grounds the relay...the relay supplies power to the horn. 700 1988
