I thought this would be of interest. I mounted the horns about 3 months ago, when I bought them from Harbor Freight. They go on sale every cpl months. I had to cut the top of the one horn to close the hood(padding on the '04's).The air compressor is mounted behind the rt air horn in the cowl opening.I got power from the pos. post in frt of the relay. I bought the fuse panel from advanced auto.Its a Bussman #BP/15600-06-20, hope these pics show enough! Tim

 

Cool. I've been contimplating getting a set of horns for my MCS as well. Just been deciding on which to get. Any sound files by any chance? I want my car to be a bog horny MINI.
Cheers,

Nope, I do not have any sound files, but it is plenty loud. I "t"ed off the horn wire to activate the relay and if you just tap horn button you get factory sound. Hold for a sec or two and you get full air horns also. Tim
