Make the connections to the Compressor (4) and the Electric Relay (6) as
shown on the wiring diagram below.
Always use vehicle terminal type connectors (not supplied) on all connections.
Never wrap wires around terminals as they could fall off. Connect terminal #30 on
the Electric Relay (6) to a 30A fused circuit.
Note: Some vehicles may employ a positive ground system. If this is the case, refer
to the wiring diagram above-left. Pay attention to polarity. If the Compressor turns on
and the Horns do not sound, reverse the Compressor connections (+ / -).

The Air Horns will now sound when the vehicle horn is pushed.
Maintenance
1.
Periodically add a few drops of light oil to each air outlet of the Compressor.
First remove air outlet tubes. Energize the Compressor. Excess oil will be
blown out. Wear ANSI approved safety glasses for this process.
2.
Periodically check the Air Horn, Relay, and Compressor hardware for
tightness. Also check for secure wire connections.
