So I drive an F150 and the horn is a two-note and says "get the f outa the way", but my ESCAPE only has one note and kinda says "toot-toot, how y'all doin!!

Question:
If I put in a two unit horn intended for an F150, is the ESCAPE horn relay gonna fry? Can I put in the F150 double horn AND leave the original ESCAPE horn working for a total of 3-horns or is this askin for trouble?

 

the fuse might fry, but doubtful, would really need to figure what each horn draws for amperage, and then what relay is good for and also fuse, but for the amount of time you use horn, should be fine depending on the draw
