Air Horn Wiring Diagram: Everything You Need to Know

Are you planning to install an air horn on your vehicle? Look no further as we provide everything you need to know about air horn wiring diagrams. In this article, we will cover the basics of air horn wiring, the different types of air horns, the step-by-step guide on how to install it, and some frequently asked questions.

The Basics of Air Horn Wiring

Before we dive into the wiring diagrams, let us first understand the basics of air horn wiring. Unlike conventional horns, air horns require a compressor to generate the loud sound. The compressor will supply compressed air to the horn, which causes the diaphragm to vibrate and produce sound.

When wiring an air horn, you will need to connect three components: the horn, the compressor, and the switch. The switch is the one that activates the compressor, which will then supply air to the horn to produce sound.

The Different Types of Air Horns

There are two main types of air horns: the single-tone and the multi-tone. The single-tone air horn produces a single loud note, while the multi-tone air horn produces a sequence of different notes.

Moreover, air horns can also differ in size, shape, and sound level. The sound level rating is measured in decibels (dB). Keep in mind that the higher the dB rating, the louder the sound of the air horn.

Step-by-Step Guide on How to Install an Air Horn

Step 1: Choose a Suitable Location

The first step in installing an air horn is to choose a suitable location for the compressor and horn. It is recommended to install the compressor in a dry and cool area, away from direct sunlight and moisture.

Make sure that the location is easily accessible for maintenance and repair purposes. Additionally, the horn should be mounted in a visible area, but not obstructing any parts of the vehicle.

Step 2: Mount the Compressor and Horn

Mount the compressor and horn using the provided brackets and screws. Make sure that the mounts are secure and do not vibrate or move while the vehicle is in motion.

Step 3: Connect the Wiring

Connect the wiring according to the wiring diagram provided with the air horn kit. The switch should be connected to a power source that is only active when the ignition is turned on.

Additionally, it is recommended to use a relay to control the power supply to the compressor. This will prevent the switch from burning out and ensure that the compressor only turns on when needed.

Step 4: Test the Air Horn

Test the air horn to make sure that it produces the desired sound level and sequence. Adjust the pressure regulator on the compressor to adjust the sound level and sequence of the air horn.

Step 5: Secure and Tie Up Wires

Secure and tie up the wires to prevent them from getting damaged or interfering with other parts of the vehicle. Use zip ties or wire loom to organize the wires and prevent them from dangling or rubbing against sharp edges.
