Bosch Relay Wiring Diagram For Horn Also, the working principle of the horn relay is simple: when you press the horn button, a low current flows from the switch to the relay. in turn, the relay boosts the signal to a current sufficient to run the horns at the end of the circuit. thus, when your horn relay is faulty, it lowers the efficiency of the entire horn system. Step 1: identify and disconnect the original horn cable. locate the existing horn and disconnect its wires. most horns are found near the battery because the position is strategic and convenient – fewer cables are required. insert the key into the ignition port and turn it to the on position.
