i installed a radio shack two tone chime
#2730071
it has a non-annoying ding dong chime
installation: the chime has polarity, it will only work one way
this makes installation easy no relays, diodes or anything else needed
i hooked mine to the dash lights and any key on circuit:
that's it
i used double sided tape to stick the chime to the top of my fuse panel
here is a video so you can hear the chime (jump to 7:15) to skip all the annoying dialogue
