David installed the Dual Trumpet Truck Air Horn and 275c Viair Compressor 1 Gallon Air System in his 2010 Chevy Silverado 1500 Crew Cab 4×4.

Assured Automotive Company sell Train Air Horns as well as Air horns for Trucks and Cars.

The first thing that was installed was the one gallon Viair Air Tank.

The Viair air tank was installed in auxiliary battery tray behind the headlight.

Using the exiting holes, the tank mounted perfectly with ease.

The Viair 275c Compressor was mounted behind the front driver side headlight near the tank.

The Viair Compressor is behind the splash guard and is securely mounted using the 3 of the required 4 bolts, with 2 addtional holes needed to be drilled.

Because the compressor is basically mounted to a body panel and the frame, you can hear and feel the compressor when it runs.

David states that the sound and vibration of compressor in cab is tolerable and definitely can be lived with.

Now for the fun part, installing the Assured Performance ACHRSK-106 Truck Horn.

You can see the backs of the horns on the right side of the picture.

The install of the horns were quick and clean.  David mounted the horn vertically behind  the grill, near the Viair compressor.

Two holes needed to be drill in the grill to mount the air horn bracket to.

The decision to face the horns vertically, with the trumpet opening facing downward is a great decision.

This doesn’t allow any moisture from rain or snow to accumulate in the trumpets or in the diaphragm housings.

All horns should be mounted at a downward angle as much as possible.

Once the grill was reinstalled everything is well hidden from the outside of the Silverado.

From the inside the engine compartment the only thing that is really visible is the Viair air tank.

That is what we call a super clean install.

The included pressure switch and relay was wired in the engine compartment near the fuse box.

The trigger wire for the relay, the wire for the horn solenoid and some quarter inch tubing for the gauge was feed through the cabs firewall.

A hole was drilled near the brake booster and reservoir.

Custom Wiring Install of Truck Air Horn

After the tubing for the gauge and the relay trigger wire was ran into the cab, it was feed into the Chevy Silverado’s center console.

Another wire from under the dash that was an ignition source was also ran to the console.  These are only trigger wires, so installers can use thin wire like 16 gauge.

The two wire were connected to the switch in the gauge panel.

The tubing was plumbed to the gauge with the included compression fitting.

The wire that was feed from the horn solenoid was ran under the dash to a SPDT switch so user can switch from OE horn to Air Horn.

When steering wheel horn switch (OE Switch) is pressed, it will now sound the air horns.

David did a great job installing this horn.  He stated his friends are envious of him.

We are confident that David will be back when he needs another Air Horn for Truck
