I am looking to do some horn modifications and I can't locate the horn. I know by sound it's in the vicinity of the battery area, but I am guessing its hidden under something. My dad bought me a horn that has the "ooga" sound on it. I want to add that one if I can find room somewhere because its kind of big, but I also want to change out the stock horn. I like the horn the mustangs have (or at least ours does). It has a multi-tone sound. Contour horns are just boring because they only have one tone. BTW, I have a 99 SE Sport with V6 duratec. Thanks for any help.
