hey yall
i just wanted to show yall this new addition to my great truck. i got a train horn from ebay for $50. it was a "blemish" (scratches in the chrome) whoopdedoo lol. it came with the solenoid and mouting hardware. so i put a 5gal air tank in my toolbox and ran a air line to the horn. i wired a switch into the factory horn wires so i can choose between the oem horn and the big one lol. i put the switch in the dash right next to the dimmer switch for dash lights for quick switches

. i put the horn under the hood. theres a big spot on the left if ur looking @ the radiator from the grille. anyway, it was pretty easy. yall should try it

. it cost me like $100 total. just get a cheap tank off craigslist or somthin.
the tank in the toolbox
the hose between the bottom of the box and the bed liner. i just ran it thru the drain hole (turn ur head) lol
