Is everything includes to install?
View Staff Answer 

The Hella 003399803 Twin Supertone Horn Kit includes both horns, a relay and install instructions. (Wiring and connectors must be purchased separately.)

Can this be mounted in original horn spot and connect with original wiring from truck horn?
View Staff Answer 

The HELLA 003399803 TWIN SUPERTONE HORN KIT can be wired into the factory horn circuit but the power supplied by the factory horn circuit will not be adequate to produce the cited 118 dB. In order for the HELLA 003399803 TWIN SUPERTONE HORN KIT to function properly it will need its own relayed circuit.

Does it sound like a real semi truck
