Helpful Notes

• Onboard air is recommended: Train horns need a tank (commonly 0.5–2.5 gal) and a compressor; kits like HP10163 simplify the install.
• Mounting ideas: Tanks often fit along the frame rail or under the bed; keep lines away from heat and abrasion.
• Wiring: Use a fused relay and pressure switch; protect feed lines with loom and grommets.
• Condensation: Drain the tank periodically (add a petcock) to protect valves and horns.
• Local rules: Check noise ordinances and use responsibly.

Frequently Asked Questions

Do I need onboard air for train horns?

Yes—train horns require compressed air. Choose a kit like the Pacbrake HP10163 or a larger-tank system if you want longer blast time.

What horn style should I choose—single, dual, or triple?

Single is compact and loud; dual adds tone; triple delivers the classic train chord. See HP10073 Dual and HP10314 Triple.

Where should I mount the horns on a 2nd Gen?

Common spots are behind the front bumper, along the frame, or under the bed—keep trumpets pointed down-ish to shed water and avoid debris.

Can I control the horn from a dash switch?

Yes—use a durable momentary like the Kleinn 320 with a relay, or integrate with Pacbrake pressure-switch wiring.

Do these kits fit 1994–1998 trucks specifically?

Most horn and onboard air kits are universal—they install cleanly on 12-valves with basic brackets, wiring, and air-line plumbing. See our featured kits above for good starting points.
