I think most of you may agree that the stock horn lacks sound. (My wife says it’s like flipping someone off with her pinky finger!)
So I went to a U-pull-it junk yard and got a duel horn off a late 80’s Cadillac Seville. (I can verify the exact year & model if anyone is interested.)
These horns bolted up very nicely in the stock locations and only had to drill two small 3/16 holes for the locking tab to engage.
The factory wiring was also used so no cutting/splicing.
I removed the grill (3 screws & two locking tabs)
The mounts on the new horns had a course threaded hole which I drilled out using a 3/8 drill bit, then de-burred the hole.
Then I unbolted the factory horn & lined up the hole and marked the spot for the locking tabs’ hole. I then centere-punched that location & drilled a 3/16 hole.
I bolted it in, hooked & it up. 30 Minutes.
I am very impressed on how little modification I ended up doing. Some horns I looked at needed to be cut or bent to fit. Not these!
I have a small mpg file on how it sounds, but this site wouldn’t support that format (AFAIK) unless someone can tell me how to do it.
Thanks,
Dean
