I ran a 16 gauge wire directly from the battery (with an in-line fuse) to the relay. The relay is triggered by the horn switch in the steering wheel by using the connections that normally go to one of the OEM electric horns. The relay then allows the air horn to get this power directly from the battery, but only when switched by the horn button.
