Horn Installation
HORN MOUNTING
Identify a suitable area for mounting, preferably an unobstructed sheet-metal surface like the frame or body of the vehicle so as to provide a firm platform which will help protect the horn from damage due to excessive shaking. Do not attach the horn to any plastic or other flexible material.
Using the bracket as a guide estimate and mark the positions for the holes and then perforate to size using a drill.
Use the provided mounting hardware to fasten the horn.
ELECTRICAL CONNECTIONS (FACTORY HORN SWITCH)
For vehicles with a two-terminal factory horn, transfer the wires to the compressor?? terminals. If the horn doesn?? sound even if the compressor motor turns on, simply reverse the wires.
For vehicles with one-terminal factory horns, make sure you transfer the wire to the compressor?? positive (+) terminal. The negative (-) terminal uses a 16-gauge wire or heavier to connect to ground.
ELECTRICAL CONNECTIONS (NEW HORN BUTTON)
In a dry location, install the relay provided making sure that terminals face downwards near the horn.
Using a 16-gauge wire or heavier, connect PIN 87 of the relay to the positive (+) terminal of the compressor.
Connect PIN 85 of the relay to the horn button (not provided). The other horn button terminal is attached to any rust and paint free metal to ground. Connect using an 18-gauge wire or heavier.
Connect PIN 30 and 86 of the relay to the battery, alternator or other positive (+) of 12-volts. Make sure the wire used is a 16-gauge wire or heavier. Use a 20A fuse (not provided) to protect the electrical circuit.?
Compressor
Compressor:MOUNTING
The ideal location for the compressor to be installed is a dry area inside your engine compartment where it will be safe from exhaust and engine manifold heat.
To make the compressor firm and secure, drill a hole of 3/16". IMPORTANT: The compressor must be mounted vertically (with air exhaust port facing downward).
Install the bolt?? head into the compressor housing?? slot. Tighten the compressor firmly to the vehicle with the provided lock washer and nut.
AIR LINE INSTALLATION
Connect one side of the airline to the compressor?? air exhaust port and the other side to the trumpet's barbed fitting.
Do not make any sharp bends or kinks in the tubing which could alter the sound of the horn or even restrict airflow.
