Frequently Asked Questions

The Mini Outlaw 127H requires specific mounting space: the horn itself measures 16.5" x 14.5" x 11" and the Air Source Unit measures 15.2" x 5.9" x 12.8". Ensure your 2012 Ford F250 has adequate clearance in both locations before installation.

The Mini Outlaw 127H operates on a 12-Volt DC electrical system with an 18-amp maximum draw. The kit includes 22 feet of wiring (10-gauge red and 18-gauge blue/grey) to connect the system to your truck's electrical system.

The 1.5-gallon air tank fills from 0-120 PSI in 2 minutes 10 seconds (±10 seconds). After a 5-second honk, the recovery time from 90-120 PSI is 35 seconds (±5 seconds), making it ready for repeated use quickly.

The system operates at 120 PSI and automatically restarts the compressor when pressure drops to 90 PSI. The 2L compressor has a maximum duty cycle of 25% at 100 PSI to ensure reliable operation and longevity.

The Mini Outlaw 127H includes a 2-year manufacturer's defect warranty and 30-day satisfaction guarantee. Important note: detaching the compressor from the tank will void your warranty, and physical damage is not covered under warranty.

The complete kit includes the train horn assembly (10.9 lbs), 1.5-gallon 4-port air tank, 2L air compressor, 22 feet of wiring, 20 feet of 1/4' air line, mounting hardware, and detailed installation instructions for proper setup.
