Jacob's 2013 BMW X5 Diesel is a testament to the adage, "where there's a will, there's a way." Against the compact nature of his SUV, Jacob skillfully installed the Conductor's Special 232 Train Horn Kit, showcasing an ingenious utilization of space. The initial step involved removing the plastic underbelly to repurpose the area originally housing the passive Diesel Exhaust Fluid Tank (DEF Tank). He then crafted a custom bracket to hold three of the Shocker XL Train Horn bells, ensuring a snug fit. Given the desire for a complete train horn sound and the space constraint, Jacob creatively zip-tied the fourth bell to the bracket, achieving the desired fit.
The installation journey continued with Jacob routing two small 16-gauge wires under the carpet to the front console, where he integrated a custom button within the ashtray to serve as the horn button. The air line from the horns were extended to the onboard air system in the rear trunk storage space. A minor modification was required: a plug for the top port and a T-fitting on the side port to ensure the compartment could close seamlessly. For a cleaner setup, Jacob installed his quick connect hose line next to the tank using an additional mount.
The outcome? A sleek, discreet installation that embodies functionality and aesthetic appeal. Jacob's 2013 BMW X5 Diesel may not scream attention at first glance, but with a press of the horn button, it's a whole different narrative. The potent sound of the Conductor's Special 232 Train Horn Kit ensures that his presence on the road is anything but unnoticed, proving that you don't need a colossal show truck to boast one of our loudest train horns.
