OK, I'll just go ahead and post the pics here too. I was trying to avoid repetition, since mine are not dissimilar to those of others who have gone in from underneath.

New horns installed and ready for use in anger! LOL! This is why I needed a 13mm socket and you may not....I installed my horns one above the other, since there was a bolt hanging around below the stock horn bolt that seemed to be doing not much of anything:

That tool set looks an awful lot like mine, Mr. Walsh. I have the same vintage of everything!
I should post a photo of the tool set needed to make the NEMA L6-20 to 14-30 adapter so you can see.

In any case, I think I got the identical result to you. Unfortunately, I didn't use a lock washer or locking thread compound on my horns, so I'll have to go in again sometime to correct that.

Nice photos (and the links all worked for me).

I didn't go for air horns of any type because I am concerned that, while they're louder, they require a fraction of a second to generate sound. First-hand observation in several air horn installations as well as various accounts from others confirm that. I believe that it's because an air horn compressor/reservoir of a size practical for use on cars and motorcycles would be too small to supply the necessary air volume and pressure to sound the horn(s) immediately upon hitting the horn switch.

A wake-the-dead air horn would be very satisfying to use when one really needs to "voice" one's displeasure, but when I use the horn, it's almost always because I need to use it right now so I don't want to trade the reaction time for sound volume.

Well.... I guess not, now that you've pointed out the technical defects. :lol:

I use the FIAMM air horns on both my Minis.....they spool up in milliseconds. Any delay is imperceptible.

Just wanted to chime in (or perhaps honk in?) that I also upgraded to the FIAMMs yesterday. Was very easy to come from the top and removing the coolant tank was much less scary than I had expected. I used a couple of adjustable wrenches to clamp the hoses down. Was a bit of a trick to figure out which arrangement to mount the horns in as the brackets I received with the FIAMMs were straight rather than having bends at the end like those in the photos. Definitely sounds way better now!

Here is a cheap easy one. I calls for a 10A fuse, so direct hook-up to car seems easy.

After two near misses from lane changes into me, I finally did my horn upgrade yesterday. I found a set of new horns on ebay that were actually for a Lincoln Town Car.(400HZ & 500HZ) The only reason I chose them is that they were mounted on a bracket that looked like it would fit them easily on the factory bracket in my car. I went into the car from the top and it was not easy for my big hands to get in there, but I finally accomplished it. I just can't imagine why they put that wimpy cookie horn in the car!!
