Thanks a bunch for this DIY - literally every passenger I've taken in my car has triggered the ear piercing honk. One time I did it in the garage on accident and the reverberation scared the crap out of me, lol. Just something that had to go.
Here's some pics and a sound clip that will hopefully help someone else who found this thread through search:
The silver round piece below the red connectors is the original horn. The red connectors are terminal spade connectors that I have folded over to plug into the socket. You can see the white twisty tie above it where I've attached the Piezu buzzer (temporary, couldn't find my zip ties).
Still a little loud for me so I might insulate the buzzer a little more.
T A P A R: I am a colorblind electrical idiot! Could you please post a pic of the "terminal spade connector...folded over"?? Tryin to figure out how to connect my new 82 cent buzzer!!! How does one determine polarity as I couild not find any indicator(s)....Sparky, "Free advice on any subject"

I just did this mod myself, as I had removed that horn all together for my Water-Methanol pump. Then I saw this and decided to put a beeper in its place. Good easy mod. I just wired it and pressed the door handle with the hood still opened, and it beeped. If it does not beep, switch the two wires around.
Imagine taking the two prongs and folding them on top of each other with some pliers to double the thickness. That's what I did. It's still not the most solid connection but more solid than just jamming the wires in there. I also wrapped the plug and this connector in electrical tape to keep the joint together.
To determine polarity, I stuck the the multimeter probes in and measured the voltage. I can't remember if this worked or not, or if I just resorted to plan B and did what Therock88 said and flipped the polarity until it made noise.
