I just finished a day project of swapping the 4 note horns off of a 1992 Cadillac Sedan Deville into my 2012 Corolla S.

No drilling or electrical modifications were necessary to make this work; the factory horn was removed, a custom mount built, horns wired, and the factory horn pigtail plugged directly into the trigger side of a standard relay.

The horns are mostly hidden behind the crash bar and condenser, the bumper hides the rest.

Pictures of the horns and mount will come after I take them off for paint.

I don't have a video of before; go outside and honk your own horn if you want to hear that awful noise. tango_face_smile_big.png

Here is the after...

Nice!  Yeah, those older GM horns are pretty loud.  Good to hear that they can be installed without much issue - thanks for sharing!

That's awesome sounding! I did a big air horn on my Celica (tankless compressor) and it's loud, sounds like a big truck, but that Delco 4 note has a special place in my heart and puts special brown stains in many underpants.
