The High tone is indicated in raised letters located on the perimeter of the horn. The 1971-73 almost uses the same horn and bracket as the 1967-68, but was mounted at a different angle, so if you have a 1971-73 you will need to loosen the screw that holds the horn to the bracket and rotate the horn to the correct position. Replaces Ford Part # C7ZZ-13832. These horns are close but not correct for a Cougar. 1967-68 Cougars used part number C7WF-13802-B Lo / C7WF-13801-B Hi and 1971-73 used D0DF-13802-A Lo / C8DF-13801-A Hi , the mounting brackets are indexed slightly differently, and the electrical connector is indexed differently too. We do offer the correct used Cougar horns.
NOTE* - Low tone horn is on the driver side
