Pointing at air horn assembly
Here you can see the entire air horn assembly. This is looking down through the front of the car between the headlights, under the center panel when the "Nissan" logo is. Normally the air filter would be in the way here, its removed for this shot. Basically, I got a length of 'L' shaped steel with pre-drilled holes. I attached an air compressor to it (far left), 3 air horns of different sizes and a relay. You can see the air hose coming out the compressor into a 3 way splitter and to each of the horns. All elecric connections are robust, labelled and routed neatly along the steel member using zip ties to hold them in place. The entire module bolts on to the front of the unibody rails of the car and has only one electrical connection which connects directly to where the stock horn would have connected. A much needed improvement over the incredibly quiet stock horn piezo.
