Air Horn?

If I wanted to put an Air Horn on my 95 V8 LX where would I even start? Where is the factory horn located? thanks

Factory horns are usually located in the engine compartment close the the front grille.

Would you happen to know where the factory horn is located on the T-bird? Perhaps a pic so I know? I've never installed an air horn but always wanted one. Thanks
