if you want a good horn, go to junk yard and get one off a 70 year ford, or early 90's ford.. i got a 93 taurus and the horn on it is alot louder than what came with our
96 contour..... and you can adjust the screw on the horn to get the pitch that you want.. and when it is correct you just paint some ladies fingernail polish on the screw so it does not move and go off the pitch you want...
on a contor you gotta take off the plastic shield under the fornt of the car to get to it.... hope this helps.
