Conductor's Special — Preparing For Your Install

Take your time, plan fitment, and install by the book so your Conductor's Special outlasts the vehicle it goes on.

  • What you need: your Conductor's Special kit, the printed instructions, basic hand tools, and a plan for where each component will mount

Getting Ready

Your boxes finally arrived and you can't wait to get the horns on. As much as you want to rush into a neighborhood test run, taking your time and following the instructions is the best way to make sure the kit lasts. Plan where each piece will fit before you force anything into place — rushing and cramming components is a sure way to damage the kit or make maintenance harder later.

Even if this is not your first horn kit, review the instructions so you do not install in a way that can damage the system or void the warranty.

Major Components

Keep these install points in mind for the tank, compressor, valve, and horns.

1

Air tank — drain at the lowest port

Your air tank can be positioned any way that fits best, but install the drain cock on the bottom-most port so moisture drains properly.

HornBlasters tanks include ports on the top, bottom, ends, and side so you can drain correctly no matter how you orient the tank. If moisture cannot drain over time, it will find its way into the horns and other components and can lead to failure.

2

Compressor — mount upright

The compressor is the heart of the system. Mount it upright so heat dissipates quickly and the unit stays efficient over time.

If the compressor can get wet or dusty, relocate the air filter. Weather-resistant kits include a relocation kit (like a snorkel), and the next articles in this series cover that process.

3

Air valve — follow the arrow

The electric air valve is closed by default and opens when it receives power. The most common mistake is installing it backward.

Inline valves are directional. Look for the arrow on the valve body and point it toward the horns (direction of airflow). Installed backward, the valve will not seal fully and the horns may hum constantly.

Valve leads are dual-polarity — either wire can be power or ground.

Horns — mount securely, mind air-line length

Shocker trumpets are individually mountable and can be separated for fitment. Face them in any direction, and mount each bell securely.

The kit includes enough air line to run each bell about 2.5 feet from the solenoid and the valve about 17 feet from the tank. Spread the bells farther than 2.5' and you will need extra line. These horns can reach up to 147.4 dB @ 150 PSI.
